示例：以代码形式创建工作流程
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：
SampleCode\CS\Process\Workflows\CreateAWorkflow.cs
要求
您必须在内部部署服务器上启用对自定义 XAML 工作流的支持。 有关详细信息，请参阅启用或禁用 XAML 工作流。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
以下示例演示如何在代码中（而不是使用工作流编辑器或设计器）以编程方式创建异步工作流。 因为 Microsoft Dynamics 365 (online) 中不支持自定义 XAML 工作流，所以此示例仅适用于 Microsoft Dynamics 365 部署（内部部署）。
