问题描述

我有一些很难理解的代码.有人可以帮我逐行分解吗?

I have some codes that i find very hard to understand. Can someone help me break it down line by line?

Service1Client client = new Service1Client();
            client.getPrimaryListCompleted += new EventHandler<getPrimaryListCompletedEventArgs>(AddPrimaryMarkerGraphics);
            client.getPrimaryListAsync();

推荐答案

第一行创建类Service1Client的实例.

第二行为事件getPrimaryListCompleted连接事件处理程序.

The second line hooks up an event handler for the event getPrimaryListCompleted.

第三行启动异步请求.当有响应时，将触发getPrimaryListCompleted，以便事件处理程序可以使用该响应.

the third line starts an asynchronous request. When there is a response, the getPrimaryListCompleted will be triggered so that the event handler can use the response.
