Ho avuto la stessa situazione e tutte le risposte che ho trovato qui e altrove non mi hanno aiutato o non sono state soddisfacenti:
Il Thread.CurrentUICulturecambia il linguaggio delle eccezioni .net, ma non per i Win32Exception, che utilizza risorse di Windows nella lingua della UI di Windows stesso. Quindi non sono mai riuscito a stampare i messaggi Win32Exceptionin inglese anziché in tedesco, nemmeno usando FormatMessage()come descritto in
Come ottenere Win32Exception in inglese?
Pertanto ho creato la mia soluzione, che memorizza la maggior parte dei messaggi di eccezione esistenti per diverse lingue in file esterni. Non otterrai il messaggio esatto nella lingua desiderata, ma riceverai un messaggio in quella lingua, che è molto più di quello che ricevi attualmente (che è un messaggio in una lingua che probabilmente non capisci).
Le funzioni statiche di questa classe possono essere eseguite su installazioni Windows con lingue diverse:
CreateMessages()crea i testi specifici della cultura e
SaveMessagesToXML()li salva in tutti i file XML quante sono le lingue create o caricate
LoadMessagesFromXML()carica tutti i file XML con messaggi specifici della lingua
Quando crei i file XML su diverse installazioni di Windows con lingue diverse, avrai presto tutte le lingue di cui hai bisogno.
Forse puoi creare testi per lingue diverse su 1 Windows quando hai installato più language pack MUI, ma non l'ho ancora testato.
Testato con VS2008, pronto per l'uso. Commenti e suggerimenti sono benvenuti!
