Data di pubblicazione: novembre 2016
Si applica a: Dynamics CRM 2015
Questo codice di esempio è per Aggiornamento di Microsoft Dynamics CRM 2015 e Microsoft Dynamics CRM Online 2015.Scarica il pacchetto SDK di Microsoft Dynamics CRM. È disponibile nel percorso seguente nel pacchetto di download:
SampleCode\CS\BusinessDataModel\UsersAndRoles\RemoveRoleFromUser.cs
Requisiti
Per ulteriori informazioni sui requisiti per l'esecuzione del codice di esempio fornito nell'SDK, vedi Utilizzare il codice di esempio e dell'helper.
Dimostra
In questo esempio vengono illustrate le procedure per annullare l'associazione tra un ruolo e un utente utilizzando il metodo IOrganizationService.Disassociate. Un frammento di codice che visualizza solo le sezioni principali dell'esempio viene visualizzato per primo, seguito da Codice di esempio completo. Si noti che questo esempio può essere eseguito solo in un ambiente locale perché crea un utente. Tuttavia, la sezione dell'esempio che dimostra l'annullamento dell'associazione di un ruolo da un utente funzionerà per tutti gli ambienti.
