Crea un collegamento sul desktop

Voglio creare un collegamento che punta a qualche file EXE, sul desktop, utilizzando .NET Framework 3.5 e affidandomi a un'API ufficiale di Windows. Come lo posso fare?

Con opzioni aggiuntive come hotkey, descrizione ecc.

Inizialmente, Progetto > Aggiungi riferimento > COM > Modello a oggetti Windows Script Host.

using IWshRuntimeLibrary;

private void CreateShortcut()
{
  object shDesktop = (object)"Desktop";
  WshShell shell = new WshShell();
  string shortcutAddress = (string)shell.SpecialFolders.Item(ref shDesktop) + @"\Notepad.lnk";
  IWshShortcut shortcut = (IWshShortcut)shell.CreateShortcut(shortcutAddress);
  shortcut.Description = "New shortcut for a Notepad";
  shortcut.Hotkey = "Ctrl+Shift+N";
  shortcut.TargetPath = Environment.GetFolderPath(Environment.SpecialFolder.System) + @"\notepad.exe";
  shortcut.Save();
}

Scorciatoia URL

private void urlShortcutToDesktop(string linkName, string linkUrl)
{
    string deskDir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);

    using (StreamWriter writer = new StreamWriter(deskDir + "\\" + linkName + ".url"))
    {
        writer.WriteLine("[InternetShortcut]");
        writer.WriteLine("URL=" + linkUrl);
    }
}

Collegamento dell'applicazione

private void appShortcutToDesktop(string linkName)
{
    string deskDir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);

    using (StreamWriter writer = new StreamWriter(deskDir + "\\" + linkName + ".url"))
    {
        string app = System.Reflection.Assembly.GetExecutingAssembly().Location;
        writer.WriteLine("[InternetShortcut]");
        writer.WriteLine("URL=file:///" + app);
        writer.WriteLine("IconIndex=0");
        string icon = app.Replace('\\', '/');
        writer.WriteLine("IconFile=" + icon);
    }
}

Controlla anche questo esempio .

Se si desidera utilizzare alcune funzioni specifiche dell'API, è necessario utilizzare IShellLink interfaceil IPersistFile interface(tramite l'interoperabilità COM).

Ecco un articolo che spiega in dettaglio cosa ti serve per farlo, oltre al codice di esempio.

Di seguito è riportato un pezzo di codice che non ha alcuna dipendenza da un oggetto COM esterno (WSH) e supporta programmi a 32 bit e 64 bit:

using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Runtime.InteropServices.ComTypes;
using System.Text;

namespace TestShortcut
{
    class Program
    {
        static void Main(string[] args)
        {
            IShellLink link = (IShellLink)new ShellLink();

            // setup shortcut information
            link.SetDescription("My Description");
            link.SetPath(@"c:\MyPath\MyProgram.exe");

            // save it
            IPersistFile file = (IPersistFile)link;
            string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
            file.Save(Path.Combine(desktopPath, "MyLink.lnk"), false);
        }
    }

    [ComImport]
    [Guid("00021401-0000-0000-C000-000000000046")]
    internal class ShellLink
    {
    }

    [ComImport]
    [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    [Guid("000214F9-0000-0000-C000-000000000046")]
    internal interface IShellLink
    {
        void GetPath([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszFile, int cchMaxPath, out IntPtr pfd, int fFlags);
        void GetIDList(out IntPtr ppidl);
        void SetIDList(IntPtr pidl);
        void GetDescription([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszName, int cchMaxName);
        void SetDescription([MarshalAs(UnmanagedType.LPWStr)] string pszName);
        void GetWorkingDirectory([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszDir, int cchMaxPath);
        void SetWorkingDirectory([MarshalAs(UnmanagedType.LPWStr)] string pszDir);
        void GetArguments([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszArgs, int cchMaxPath);
        void SetArguments([MarshalAs(UnmanagedType.LPWStr)] string pszArgs);
        void GetHotkey(out short pwHotkey);
        void SetHotkey(short wHotkey);
        void GetShowCmd(out int piShowCmd);
        void SetShowCmd(int iShowCmd);
        void GetIconLocation([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszIconPath, int cchIconPath, out int piIcon);
        void SetIconLocation([MarshalAs(UnmanagedType.LPWStr)] string pszIconPath, int iIcon);
        void SetRelativePath([MarshalAs(UnmanagedType.LPWStr)] string pszPathRel, int dwReserved);
        void Resolve(IntPtr hwnd, int fFlags);
        void SetPath([MarshalAs(UnmanagedType.LPWStr)] string pszFile);
    }
}

È possibile utilizzare questa classe ShellLink.cs per creare il collegamento.

Per ottenere la directory del desktop, usa:

var dir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);

o usalo Environment.SpecialFolder.CommonDesktopDirectoryper crearlo per tutti gli utenti.

Senza ulteriore riferimento:

using System;
using System.Runtime.InteropServices;

private static Type m_type = Type.GetTypeFromProgID("WScript.Shell");
private static object m_shell = Activator.CreateInstance(m_type);

public static void Create(string fileName, string targetPath, string arguments, string workingDirectory, string description, string hotkey, string iconPath)
{
    IWshShortcut shortcut = (IWshShortcut)m_type.InvokeMember("CreateShortcut", System.Reflection.BindingFlags.InvokeMethod, null, m_shell, new object[] { fileName });
    shortcut.Description = description;
    shortcut.Hotkey = hotkey;
    shortcut.TargetPath = targetPath;
    shortcut.WorkingDirectory = workingDirectory;
    shortcut.Arguments = arguments;
    if (!string.IsNullOrEmpty(iconPath))
        shortcut.IconLocation = iconPath;
    shortcut.Save();
}
}

Per creare un collegamento sul desktop:

    string lnkFileName = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Notepad.lnk");
    Shortcut.Create(lnkFileName,
        System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), "notepad.exe"),
        null, null, "Open Notepad", "Ctrl+Shift+N", null);

Uso semplicemente per la mia app:

using IWshRuntimeLibrary; // > Ref > COM > Windows Script Host Object  
...   
private static void CreateShortcut()
    {
        string link = Environment.GetFolderPath( Environment.SpecialFolder.Desktop ) 
            + Path.DirectorySeparatorChar + Application.ProductName + ".lnk";
        var shell = new WshShell();
        var shortcut = shell.CreateShortcut( link ) as IWshShortcut;
        shortcut.TargetPath = Application.ExecutablePath;
        shortcut.WorkingDirectory = Application.StartupPath;
        //shortcut...
        shortcut.Save();
    }

Usa ShellLink.cs su vbAccelerator per creare facilmente il tuo collegamento!

private static void AddShortCut()
{
using (ShellLink shortcut = new ShellLink())
{
    shortcut.Target = Application.ExecutablePath;
    shortcut.WorkingDirectory = Path.GetDirectoryName(Application.ExecutablePath);
    shortcut.Description = "My Shorcut";
    shortcut.DisplayMode = ShellLink.LinkDisplayMode.edmNormal;
    shortcut.Save(SHORTCUT_FILEPATH);
}
}

EDIT: non consiglio più questa soluzione. Se non esiste ancora un metodo migliore dell'utilizzo del motore di scripting di Windows, utilizza almeno la soluzione di @ Mehmet che chiama direttamente il motore anziché creare uno script di testo normale in memoria.

Abbiamo utilizzato VBScript per generare un collegamento. Non necessita di p / Invoke, COM Interop e DLL aggiuntive. Funziona così:

• Genera un VBScript in fase di esecuzione con i parametri specificati del metodo CreateShortcut C #
• Salva questo VBScript in un file temporaneo
• Attendi che lo script finisca
• Elimina il file temporaneo

Ecco qui:

static string _scriptTempFilename;

/// <summary>
/// Creates a shortcut at the specified path with the given target and
/// arguments.
/// </summary>
/// <param name="path">The path where the shortcut will be created. This should
///     be a file with the LNK extension.</param>
/// <param name="target">The target of the shortcut, e.g. the program or file
///     or folder which will be opened.</param>
/// <param name="arguments">The additional command line arguments passed to the
///     target.</param>
public static void CreateShortcut(string path, string target, string arguments)
{
    // Check if link path ends with LNK or URL
    string extension = Path.GetExtension(path).ToUpper();
    if (extension != ".LNK" && extension != ".URL")
    {
        throw new ArgumentException("The path of the shortcut must have the extension .lnk or .url.");
    }

    // Get temporary file name with correct extension
    _scriptTempFilename = Path.GetTempFileName();
    File.Move(_scriptTempFilename, _scriptTempFilename += ".vbs");

    // Generate script and write it in the temporary file
    File.WriteAllText(_scriptTempFilename, String.Format(@"Dim WSHShell
Set WSHShell = WScript.CreateObject({0}WScript.Shell{0})
Dim Shortcut
Set Shortcut = WSHShell.CreateShortcut({0}{1}{0})
Shortcut.TargetPath = {0}{2}{0}
Shortcut.WorkingDirectory = {0}{3}{0}
Shortcut.Arguments = {0}{4}{0}
Shortcut.Save",
        "\"", path, target, Path.GetDirectoryName(target), arguments),
        Encoding.Unicode);

    // Run the script and delete it after it has finished
    Process process = new Process();
    process.StartInfo.FileName = _scriptTempFilename;
    process.Start();
    process.WaitForExit();
    File.Delete(_scriptTempFilename);
}

Ecco un metodo di estensione (testato), con commenti per aiutarti.

using IWshRuntimeLibrary;
using System;

namespace Extensions
{
    public static class XShortCut
    {
        /// <summary>
        /// Creates a shortcut in the startup folder from a exe as found in the current directory.
        /// </summary>
        /// <param name="exeName">The exe name e.g. test.exe as found in the current directory</param>
        /// <param name="startIn">The shortcut's "Start In" folder</param>
        /// <param name="description">The shortcut's description</param>
        /// <returns>The folder path where created</returns>
        public static string CreateShortCutInStartUpFolder(string exeName, string startIn, string description)
        {
            var startupFolderPath = Environment.SpecialFolder.Startup.GetFolderPath();
            var linkPath = startupFolderPath + @"\" + exeName + "-Shortcut.lnk";
            var targetPath = Environment.CurrentDirectory + @"\" + exeName;
            XFile.Delete(linkPath);
            Create(linkPath, targetPath, startIn, description);
            return startupFolderPath;
        }

        /// <summary>
        /// Create a shortcut
        /// </summary>
        /// <param name="fullPathToLink">the full path to the shortcut to be created</param>
        /// <param name="fullPathToTargetExe">the full path to the exe to 'really execute'</param>
        /// <param name="startIn">Start in this folder</param>
        /// <param name="description">Description for the link</param>
        public static void Create(string fullPathToLink, string fullPathToTargetExe, string startIn, string description)
        {
            var shell = new WshShell();
            var link = (IWshShortcut)shell.CreateShortcut(fullPathToLink);
            link.IconLocation = fullPathToTargetExe;
            link.TargetPath = fullPathToTargetExe;
            link.Description = description;
            link.WorkingDirectory = startIn;
            link.Save();
        }
    }
}

E un esempio di utilizzo:

XShortCut.CreateShortCutInStartUpFolder(THEEXENAME, 
    Environment.CurrentDirectory,
    "Starts some executable in the current directory of application");

1st parm imposta il nome exe (che si trova nella directory corrente) 2nd parm è la cartella "Start In" e 3rd parm è la descrizione del collegamento.

La convenzione di denominazione del collegamento non lascia ambiguità su cosa farà. Per testare il collegamento è sufficiente fare doppio clic su di esso.

Nota finale: l'applicazione stessa (destinazione) deve avere un'immagine ICON associata ad essa. Il collegamento è facilmente in grado di individuare l'ICONA all'interno dell'exe. Se l'applicazione di destinazione ha più di un'icona, è possibile aprire le proprietà del collegamento e cambiare l'icona in qualsiasi altra trovata nell'exe.

Uso il riferimento "Windows Script Host Object Model" per creare il collegamento.

e per creare un collegamento su una posizione specifica:

    void CreateShortcut(string linkPath, string filename)
    {
        // Create shortcut dir if not exists
        if (!Directory.Exists(linkPath))
            Directory.CreateDirectory(linkPath);

        // shortcut file name
        string linkName = Path.ChangeExtension(Path.GetFileName(filename), ".lnk");

        // COM object instance/props
        IWshRuntimeLibrary.WshShell shell = new IWshRuntimeLibrary.WshShell();
        IWshRuntimeLibrary.IWshShortcut sc = (IWshRuntimeLibrary.IWshShortcut)shell.CreateShortcut(linkName);
        sc.Description = "some desc";
        //shortcut.IconLocation = @"C:\..."; 
        sc.TargetPath = linkPath;
        // save shortcut to target
        sc.Save();
    }

private void CreateShortcut(string executablePath, string name)
    {
        CMDexec("echo Set oWS = WScript.CreateObject('WScript.Shell') > CreateShortcut.vbs");
        CMDexec("echo sLinkFile = '" + Environment.GetEnvironmentVariable("homedrive") + "\\users\\" + Environment.GetEnvironmentVariable("username") + "\\desktop\\" + name + ".ink' >> CreateShortcut.vbs");
        CMDexec("echo Set oLink = oWS.CreateShortcut(sLinkFile) >> CreateShortcut.vbs");
        CMDexec("echo oLink.TargetPath = '" + executablePath + "' >> CreateShortcut.vbs");
        CMDexec("echo oLink.Save >> CreateShortcut.vbs");
        CMDexec("cscript CreateShortcut.vbs");
        CMDexec("del CreateShortcut.vbs");
    }

Ho creato una classe wrapper basata sulla risposta di Rustam Irzaev con l'uso di IWshRuntimeLibrary.

IWshRuntimeLibrary -> Riferimenti -> COM> Windows Script Host Object Model

using System;
using System.IO;
using IWshRuntimeLibrary;
using File = System.IO.File;

public static class Shortcut
{
    public static void CreateShortcut(string originalFilePathAndName, string destinationSavePath)
    {
        string fileName = Path.GetFileNameWithoutExtension(originalFilePathAndName);
        string originalFilePath = Path.GetDirectoryName(originalFilePathAndName);

        string link = destinationSavePath + Path.DirectorySeparatorChar + fileName + ".lnk";
        var shell = new WshShell();
        var shortcut = shell.CreateShortcut(link) as IWshShortcut;
        if (shortcut != null)
        {
            shortcut.TargetPath = originalFilePathAndName;
            shortcut.WorkingDirectory = originalFilePath;
            shortcut.Save();
        }
    }

    public static void CreateStartupShortcut()
    {
        CreateShortcut(System.Reflection.Assembly.GetEntryAssembly()?.Location, Environment.GetFolderPath(Environment.SpecialFolder.Startup));
    }

    public static void DeleteShortcut(string originalFilePathAndName, string destinationSavePath)
    {
        string fileName = Path.GetFileNameWithoutExtension(originalFilePathAndName);
        string originalFilePath = Path.GetDirectoryName(originalFilePathAndName);

        string link = destinationSavePath + Path.DirectorySeparatorChar + fileName + ".lnk";
        if (File.Exists(link)) File.Delete(link);
    }

    public static void DeleteStartupShortcut()
    {
        DeleteShortcut(System.Reflection.Assembly.GetEntryAssembly()?.Location, Environment.GetFolderPath(Environment.SpecialFolder.Startup));
    }
}

Per Windows Vista / 7/8/10, puoi creare un collegamento simbolico invece tramite mklink.

Process.Start("cmd.exe", $"/c mklink {linkName} {applicationPath}");

In alternativa, chiama CreateSymbolicLinktramite P / Invoke.
