Consume WCF Service in Windows Phone application: methods return void

问题

I have WCF service

When I "Add Service Reference" in my windows phone application everything looks good but methods return void. I tested this server for example in WPF app and it works and returns what I need but in wp 7/8 app not. Ofcourse the basic functionality of this WCF is to return data so void methods are totally useless for me.

回答1:

You can use service Async and Completed events.Service will return data in completed event like

ServiceReference1.Service1Client clientForTesting = new ServiceReference1.Service1Client();
            clientForTesting.GetDataCompleted += new EventHandler<ServiceReference1.GetDataCompletedEventArgs>(TestCallback);
            clientForTesting.GetDataAsync(testValue);
