範例：移除使用者的角色
發行︰ 2017年1月
適用於： Dynamics 365 (online)、Dynamics 365 (on-premises)、Dynamics CRM 2016、Dynamics CRM Online
這個範例程式碼適用於 Microsoft Dynamics 365 (線上和內部部署)。下載 Microsoft Dynamics CRM SDK 套件。 可以在下列位置的下載套件中找到：
SampleCode\CS\BusinessDataModel\UsersAndRoles\RemoveRoleFromUser.cs
需求
如需執行此 SDK 所提供範例程式碼的需求資訊，請參閱使用範例和 Helper 程式碼。
示範
此範例將說明如何使用 IOrganizationService.Disassociate 方法取消使用者與角色之間的關聯。 首先是只顯示範例重點區段的程式碼片段，隨後為完整範例程式碼。 請注意此範本在內部部署環境才能執行，因為它會建立使用者。 不過，範例中示範取消使用者與角色之間關聯的區段在所有環境下都適用。
