我的Windows Workflow Foundation 之旅---(5)工作流通信例子

[上一节]

本节我们做一个工作流通信的简单例子，具体的概念请参考上一节的内容。

一. 通信服务：

新建一个“顺序工作流控制台应用程序”，然后右键解决方案→添加→新建项目→类库。如图：

Code

1 static void Main(string[] args)

2 {

3 using(WorkflowRuntime workflowRuntime = new WorkflowRuntime())

4 {

5 AutoResetEvent waitHandle = new AutoResetEvent(false);

6 ExternalDataExchangeService dataService = new ExternalDataExchangeService();

7 workflowRuntime.AddService(dataService);

8 dataService.AddService( new MessageService());

9 workflowRuntime.WorkflowCompleted += delegate(object sender, WorkflowCompletedEventArgs e) {waitHandle.Set();};

10 workflowRuntime.WorkflowTerminated += delegate(object sender, WorkflowTerminatedEventArgs e)

11 {

12 Console.WriteLine(e.Exception.Message);

13 waitHandle.Set();

14 };

15

16 Dictionary<string, object> parms = new Dictionary<string, object>();

17 parms.Add("消息","我叫无忧，大家早上好");

18

19 WorkflowInstance instance = workflowRuntime.CreateWorkflow(typeof(Demo1.Workflow1),parms);

20 instance.Start();

21

22 waitHandle.WaitOne();

23 }

24 }

运行结果如图：
