ResumeBookmark(String, Object, TimeSpan)

使用指定的值與逾時間隔啟始繼續書籤 (具有指定名稱) 的作業。要繼續的書籤是由工作流程執行個體中的活動事先建立的。

public:
 System::Activities::BookmarkResumptionResult ResumeBookmark(System::String ^ bookmarkName, System::Object ^ value, TimeSpan timeout);

public System.Activities.BookmarkResumptionResult ResumeBookmark (string bookmarkName, object value, TimeSpan timeout);

member this.ResumeBookmark : string * obj * TimeSpan -> System.Activities.BookmarkResumptionResult

Public Function ResumeBookmark (bookmarkName As String, value As Object, timeout As TimeSpan) As BookmarkResumptionResult

參數

bookmarkName: String

要繼續的書籤名稱。

value: Object

繼續書籤時，做為參數傳遞至所叫用方法的物件。

timeout: TimeSpan

書籤必須在期間內繼續的時間間隔。

傳回

BookmarkResumptionResult

書籤繼續作業的結果。

範例

下列範例會建立使用 ReadLine 活動的工作流程，而這個活動會建立 Bookmark。系統會啟動工作流程，而且一旦建立 Bookmark 並且工作流程處於閒置狀態之後，就會蒐集使用者的輸入並繼續書籤。

public sealed class ReadLine : NativeActivity<string>
{
    [RequiredArgument]
    public InArgument<string> BookmarkName { get; set; }

    protected override void Execute(NativeActivityContext context)
    {
        // Create a Bookmark and wait for it to be resumed.
        context.CreateBookmark(BookmarkName.Get(context),
            new BookmarkCallback(OnResumeBookmark));
    }

    // NativeActivity derived activities that do asynchronous operations by calling
    // one of the CreateBookmark overloads defined on System.Activities.NativeActivityContext
    // must override the CanInduceIdle property and return true.
    protected override bool CanInduceIdle
    {
        get { return true; }
    }

    public void OnResumeBookmark(NativeActivityContext context, Bookmark bookmark, object obj)
    {
        // When the Bookmark is resumed, assign its value to
        // the Result argument.
        Result.Set(context, (string)obj);
    }

Variable<string> name = new Variable<string>();

Activity wf = new Sequence
{
    Variables = { name },
    Activities =
     {
         new WriteLine
         {
             Text = "What is your name?"
         },
         new ReadLine
         {
             BookmarkName = "UserName",
             Result = new OutArgument<string>(name)
         },
         new WriteLine
         {
             Text = new InArgument<string>((env) =>
                 ("Hello, " + name.Get(env)))
         }
     }
};

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

// Workflow lifecycle events omitted except idle.
AutoResetEvent idleEvent = new AutoResetEvent(false);

wfApp.Idle = delegate(WorkflowApplicationIdleEventArgs e)
{
    idleEvent.Set();
};

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

// Wait for the workflow to go idle before gathering
// the user's input.
idleEvent.WaitOne();

// Gather the user's input and resume the bookmark.
// Bookmark resumption only occurs when the workflow
// is idle. If a call to ResumeBookmark is made and the workflow
// is not idle, ResumeBookmark blocks until the workflow becomes
// idle before resuming the bookmark.
BookmarkResumptionResult result = wfApp.ResumeBookmark("UserName",
    Console.ReadLine());

// Possible BookmarkResumptionResult values:
// Success, NotFound, or NotReady
Console.WriteLine("BookmarkResumptionResult: {0}", result);

書籤結果會指出繼續作業是成功或是失敗。
