Usa un ciclo foreach invece di un ciclo for - ha risolto il mio problema.
int j = 0;
foreach (Microsoft.Office.Interop.Word.Page p in pane.Pages)
{
var bits = p.EnhMetaFileBits;
var target = path1 +j.ToString()+ "_image.doc";
try
{
using (var ms = new MemoryStream((byte[])(bits)))
{
var image = System.Drawing.Image.FromStream(ms);
var pngTarget = Path.ChangeExtension(target, "png");
image.Save(pngTarget, System.Drawing.Imaging.ImageFormat.Png);
}
}
catch (System.Exception ex)
{
MessageBox.Show(ex.Message);
}
j++;
}
Ecco una modifica di un programma che ha funzionato per me. Utilizza Word 2007 con il componente aggiuntivo Salva come PDF installato. Cerca una directory per i file .doc, li apre in Word e li salva in formato PDF. Nota che dovrai aggiungere un riferimento a Microsoft.Office.Interop.Word alla soluzione.
