终止工作流实例。

重载

Terminate(Exception)	使用指定的异常终止工作流实例。
Terminate(String)	使用指定的错误消息终止工作流实例。
Terminate(Exception, TimeSpan)	使用指定的异常和超时间隔终止工作流实例。
Terminate(String, TimeSpan)	使用指定的错误消息和超时间隔终止工作流实例。

Terminate(Exception)

使用指定的异常终止工作流实例。

public:
 void Terminate(Exception ^ reason);

public void Terminate (Exception reason);

member this.Terminate : Exception -> unit

Public Sub Terminate (reason As Exception)

参数

reason: Exception

终止工作流实例的原因。

示例

下面的示例使用 WorkflowApplication 承载一个工作流。该示例使用指定的工作流定义构造 WorkflowApplication，处理所需的工作流生命周期事件，并通过调用 Run 来调用工作流。启动工作流之后，将调用 Terminate。终止工作流时，会向控制台显示以下输出。

Starting the workflow.   
Workflow e6b33409-f010-49f1-82ce-56f8baabe5e5 Terminated.  
Exception: System.ApplicationException  
Terminating the workflow.   
Workflow e6b33409-f010-49f1-82ce-56f8baabe5e5 unloaded.

Activity wf = new Sequence
{
    Activities =
     {
         new WriteLine
         {
             Text = "Starting the workflow."
         },
         new Delay
         {
             Duration = TimeSpan.FromSeconds(5)
         },
         new WriteLine
         {
             Text = "Ending the workflow."
         }
     }
};

// Create a WorkflowApplication instance.
WorkflowApplication wfApp = new WorkflowApplication(wf);

// Subscribe to any desired workflow lifecycle events.
wfApp.Completed = delegate(WorkflowApplicationCompletedEventArgs e)
{
    if (e.CompletionState == ActivityInstanceState.Faulted)
    {
        Console.WriteLine("Workflow {0} Terminated.", e.InstanceId);
        Console.WriteLine("Exception: {0}\n{1}",
            e.TerminationException.GetType().FullName,
            e.TerminationException.Message);
    }
    else if (e.CompletionState == ActivityInstanceState.Canceled)
    {
        Console.WriteLine("Workflow {0} Canceled.", e.InstanceId);
    }
    else
    {
        Console.WriteLine("Workflow {0} Completed.", e.InstanceId);

        // Outputs can be retrieved from the Outputs dictionary,
        // keyed by argument name.
        // Console.WriteLine("The winner is {0}.", e.Outputs["Winner"]);
    }
};

wfApp.Unloaded = delegate(WorkflowApplicationEventArgs e)
{
    Console.WriteLine("Workflow {0} unloaded.", e.InstanceId);
};

// Run the workflow.
wfApp.Run();

Thread.Sleep(TimeSpan.FromSeconds(1));

wfApp.Terminate(new ApplicationException("Terminating the workflow."));

注解

此方法会安排对工作流实例的终止操作。若要在终止完成后得到通知，请使用 Completed 处理程序。

默认情况下，Terminate 操作必须在 30 秒内完成，否则将引发 TimeoutException。

适用于

Terminate(String)

使用指定的错误消息终止工作流实例。

public:
 void Terminate(System::String ^ reason);

public void Terminate (string reason);

member this.Terminate : string -> unit

Public Sub Terminate (reason As String)

参数

reason: String

终止工作流实例的原因。
