WorkflowStatus 枚举

定义

命名空间:

System.Workflow.Runtime

程序集:

System.Workflow.Runtime.dll

注意

The System.Workflow.* types are deprecated. Instead, please use the new types from System.Activities.*

指定工作流实例的状态。

public enum class WorkflowStatus

[System.Obsolete("The System.Workflow.* types are deprecated.  Instead, please use the new types from System.Activities.*")]
public enum WorkflowStatus

[<System.Obsolete("The System.Workflow.* types are deprecated.  Instead, please use the new types from System.Activities.*")>]
type WorkflowStatus = 

Public Enum WorkflowStatus

继承

Object

ValueType

Enum

WorkflowStatus

属性

ObsoleteAttribute

字段

Completed	1	工作流实例已完成。
Created	4	已通过调用重载 CreateWorkflow(Type) 方法之一创建了工作流实例。
Running	0	工作流实例处于运行状态。
Suspended	2	工作流实例已被 SuspendActivity 活动、Suspend(String) 调用或工作流运行时引擎挂起。
Terminated	3	工作流实例已被 TerminateActivity 活动、Terminate(String) 调用或工作流运行时引擎终止。

示例

下面的代码示例演示如何使用 WorkflowStatus 值设置 WorkflowStatus 属性。 每个值都以不同的方式约束 SqlTrackingWorkflowInstance。

此代码示例摘自 DatabaseService.cs 文件中的“工作流监控”SDK 示例。 有关详细信息，请参阅 工作流监视器。
