帮助程序代码：SystemUserProvider 类
发布日期： 2017年1月
适用于： Dynamics 365 (online),Dynamics 365 (on-premises),Dynamics CRM 2016,Dynamics CRM Online
下载 Microsoft Dynamics CRM SDK 包。 可在下载包中的以下位置找到此示例：
SDK\SampleCode\CS\HelperCode\SystemUserProvider.cs
SDK\SampleCode\VB\HelperCode\SystemUserProvider.vb
要求
登录的系统用户必须对此示例代码具有系统管理特权才能新建用户帐户。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。
演示
SystemUserProvider 类演示如何以编程方式在 Active Directory 和 Microsoft Dynamics 365 中创建其他用户。
一些 SDK 示例要求在 Microsoft Dynamics 365（在线或本地） 中存在除登录用户之外的其他（虚构）系统用户，这样示例才能执行预期任务。 这些示例使用 SystemUserProvider 类方法创建所需的这些其他用户。 由于当前无法以编程方式创建新 Microsoft 帐户 用户，因此当对 Microsoft Dynamics 365 (online) 服务器运行时，代码只向控制台输出所需用户信息。 然后可以根据需要手动添加和邀请这些用户。
