无法处理FaultException

问题描述

我有一个执行操作的wcf服务。在此操作中可能会出现故障。我已经说过我的服务合同可能有问题。

i have a wcf service that does an operation. and in this operation there could be a fault. i have stated that there could be a fault in my service contract.

这是下面的代码；

public void Foo()
{
        try
        {
            DoSomething(); // throws FaultException<FooFault>
        }
        catch (FaultException)
        {
            throw;
        }
        catch (Exception ex)
        {
            myProject.Exception.Throw<FooFault>(ex);
        }
}

在服务合同中；

[FaultException(typeof(FooFault))]
void Foo();

当我在运行应用程序时，DoSomething（）方法抛出了FaultException时，首先是在 catch（Exception ex）行捕获并在那里中断。然后当我再次按f5键时，它通常会执行该操作。我不知道为什么会有这种突破？

when a FaultException was thrown by DoSomething() method while i was running the application, firstly the exception was caught at "catch(Exception ex)" line and breaks in there. then when i pressed f5 again, it does what normally it has to. i wonder why that break exists? and if not could it be problem on publish?

推荐答案

您是否正在使用Silverlight中的WCF服务？如果是这样，则需要进行特殊配置以使服务返回HTTP 200代码（如果出现错误，则返回500）。详细信息在这里：

Are you consuming the WCF service from Silverlight? If so, a special configuration is needed to make the service return a HTTP 200 code instead of 500 in case of error. The details are here: http://msdn.microsoft.com/en-us/library/dd470096%28VS.96%29.aspx
