Question

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();

Answer 1

The first line creates an instance of the class Service1Client.

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

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.
