示例：使用 ActOnBehalfOf 权限进行模拟
发布日期： 2017年1月
适用于： Dynamics 365 (online),Dynamics 365 (on-premises),Dynamics CRM 2016,Dynamics CRM Online
此示例代码适用于 Microsoft Dynamics 365（在线或本地）。下载 Microsoft Dynamics CRM SDK 包。 它可能位于下载包的以下位置：
SDK\SampleCode\CS\GeneralProgramming\Authentication\ImpersonateWithOnBehalfOfPrivilege.cs
要求
有关运行此 SDK 中提供的示例代码的要求的详细信息，请参阅使用示例和帮助程序代码。
用户（模拟者）必须拥有 ActOnBehalfOf 权限，或者是 Active Directory 中 PrivUserGroup 组的成员。
演示
此示例通过设置组织 Web 服务代理的CallerId 属性来模拟其他用户。
