Valore della proprietà

Percorso che, se anteposto al percorso file relativo specificato in un oggetto ResXFileRef, produce un percorso assoluto di un file di risorse.

Eccezioni

Esempio

L'esempio seguente crea un file di risorse XML che contiene immagini di razze cane e crea anche una risorsa stringa che specifica l'applicazione che ha creato la risorsa. ResXFileRef gli oggetti vengono usati per archiviare il percorso delle immagini anziché archiviare le immagini binarie stesse nel file di risorse. Nell'esempio viene impostata la BasePath proprietà in modo che i percorsi dei file relativi nei nomi dei file delle immagini vengano interpretati come sottodirectory di una directory denominata C:\data\.

Si noti che è necessario aggiungere un riferimento a System.Drawing.dll per compilare correttamente il progetto. L'esempio richiede inoltre che le immagini necessarie esistano in una directory denominata C:\data\images\.

Commenti

La BasePath proprietà viene usata per risolvere i riferimenti al percorso file relativi assegnati alla FileName proprietà degli ResXFileRef oggetti. Per impostazione predefinita, il relativo valore è String.Emptye i riferimenti al percorso dei file relativi vengono risolti in relazione alla directory corrente restituita dalla Environment.CurrentDirectory proprietà . È necessario impostare questa proprietà prima di iniziare a enumerare le risorse.
