如何捕获异常并调用WCF中的方法？

Question

What I'm trying to do is that I'm calling one WCF service (sever) from within another WCF service (client), server service has authentication and authorization mechanism,
when I call login method in server WCF it logged the client and creates a token that expired after amount of time, when that token expired an exception with "Access Denied" message thrown by server service.

What I want to do is to catch this exception in client service and recall the same method recalled in client with the same parameters after I do a login.
Do I have to use global error handler or IOperationInvoker class to handle it ?
I mean when my custom made token expired how could I know and recall the same method ?

您应该构建WCF服务以准备处理请求
