How to call WCF service method asynchronously? That means I need to call a service method which takes, let''s say e.g, 20 seconds. I want to call that method and let the client to do some other tasks i.e, I should not wait for the method to complete. In simple words, the progress bar in browser should not appear for 20 seconds. The browser should allow me to do other tasks in the page. How can I incorporate this?

推荐答案

生成代理类时，它将为您生成aysnc方法(假设您尚未关闭此行为).假设服务上有一个Add方法，则客户端将同时具有Add 和 AddAsync 方法，以及一个 AddCompleted 需要一个 AddCompletedEventArgs 来处理响应的事件.


MSDN clickety 此处 [

When you generate the proxy classes it genrates aysnc methods for you (assuming you haven''t switched this behaviour off). Suppose you have an Add method on the service, the client will have both Add and AddAsync methods, and an AddCompleted event that takes a AddCompletedEventArgs to handle the response.
