我想从WCF服务器抛出自定义异常,但它对我的客户端不起作用。我做什么:WCF:无法在客户端上处理FaultException <T>
我的自定义异常:
[DataContract]
public class MyCustomException
{
[DataMember]
public string MyField { get; set; }
}
我的WCF服务合同
[ServiceContract]
public interface IMyService
{
[OperationContract]
[FaultContract(typeof(MyCustomException))]
bool Foo();
}
为WCF服务我的全局异常处理程序(此代码击中时富称):
public void ProvideFault(Exception error, System.ServiceModel.Channels.MessageVersion version, ref System.ServiceModel.Channels.Message fault)
{
var ex = new MyCustomException { MyField = "..." };
var fe = new FaultException<MyCustomException>(
ex,
new FaultReason("reason"),
FaultCode.CreateSenderFaultCode(new FaultCode("some-string")));
var flt = fe.CreateMessageFault();
fault = Message.CreateMessage(
version,
flt,
string.Empty
);
}
然后...我的客户:
try
{
Create channel factory and call Foo
}
catch(FaultException<MyCustomException> ex)
{
// OOOPS! It doesn't work!!!
}
catch(FaultException ex)
{
// This block catches exception
}
这里有什么问题?先谢谢你!
