WorkflowRuntime.StopRuntime 方法

定义

命名空间:

System.Workflow.Runtime

程序集:

System.Workflow.Runtime.dll

停止工作流运行时引擎和运行时服务。

public:
 void StopRuntime();

public void StopRuntime ();

member this.StopRuntime : unit -> unit

Public Sub StopRuntime ()

例外

ObjectDisposedException

已释放 WorkflowRuntime。

示例

下面的代码示例演示如何使用工作流宿主中的 WorkflowRuntime 功能。 在宿主完成其他所有与运行时关联的处理后，将调用 StopRuntime。

此代码示例是 取消工作流示例的一 部分。

static void Main()
{
    string connectionString = "Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI;";

    using (WorkflowRuntime workflowRuntime = new WorkflowRuntime())
    {
        ExternalDataExchangeService dataService = new ExternalDataExchangeService();
        workflowRuntime.AddService(dataService);
        dataService.AddService(expenseService);

        workflowRuntime.AddService(new SqlWorkflowPersistenceService(connectionString));
        workflowRuntime.StartRuntime();

        workflowRuntime.WorkflowCompleted += OnWorkflowCompleted;
        workflowRuntime.WorkflowTerminated += OnWorkflowTerminated;
        workflowRuntime.WorkflowIdled += OnWorkflowIdled;
        workflowRuntime.WorkflowAborted += OnWorkflowAborted;

        Type type = typeof(SampleWorkflow1);
        WorkflowInstance workflowInstance = workflowRuntime.CreateWorkflow(type);
        workflowInstance.Start();

        waitHandle.WaitOne();

        workflowRuntime.StopRuntime();
    }
}

Shared Sub Main()
    Dim connectionString As String = "Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI;"
    Using workflowRuntime As New WorkflowRuntime()
        Dim dataService As New ExternalDataExchangeService()
        workflowRuntime.AddService(dataService)
        dataService.AddService(expenseService)

        workflowRuntime.AddService(New SqlWorkflowPersistenceService(connectionString))


        AddHandler workflowRuntime.WorkflowCompleted, AddressOf OnWorkflowCompleted
        AddHandler workflowRuntime.WorkflowTerminated, AddressOf OnWorkflowTerminated
        AddHandler workflowRuntime.WorkflowIdled, AddressOf OnWorkflowIdled
        AddHandler workflowRuntime.WorkflowAborted, AddressOf OnWorkflowAborted


        Dim workflowInstance As WorkflowInstance
        workflowInstance = workflowRuntime.CreateWorkflow(GetType(SampleWorkflow))
        workflowInstance.Start()

        waitHandle.WaitOne()

        workflowRuntime.StopRuntime()
    End Using
End Sub

注解

此方法使工作流运行时引擎卸载其每个工作流实例，停止从 类派生 WorkflowRuntimeService 的所有服务，将 设置为 IsStartedfalse，并引发 Stopped 事件。

若要正常关闭 WorkflowRuntime，请在调用 StopRuntime 之前调用 Dispose。

有关更多信息，请参见 Dispose 方法。
