How to Catch Exceptions in WPF when Calling a WCF Service

Question

调用WCF服务时如何在WPF中捕获异常？

Answer 1

Basically you'll have three approaches:

• Rethrow FaultException on your regular try/catch
• Mark your OperationContract with FaultContract attribute and translate your Exception to your custom Fault object, manually
• To implement a IErrorHandler behavior and let it handle WCF exceptions to you
