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。

    }

    // NativeActivity derived activities that do asynchronous operations by calling

    public void OnResumeBookmark(NativeActivityContext context, Bookmark bookmark, object obj)

        // the Result argument.

                 ("Hello, " + name.Get(env)))
         }
     }
};

// Create a WorkflowApplication instance.

// 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);
