如何解决'System.ServiceModel.ExceptionDetail'未标记为可序列化

我有一个ASP.net网站调用的WCF Web服务。在我的web方法中，我故意不捕捉异常，因为我希望它们能够由客户端网站处理。 Web服务纯粹是一个内部应用程序，我希望它的行为像一个标准库，它希望调用者处理异常。我在服务web.config中有includeExceptionDetailInFaults =“true”。当我的服务抛出一个异常，我得到这个错误：如何解决'System.ServiceModel.ExceptionDetail'未标记为可序列化

如何解决这个问题，所以我的客户能够赶上由服务引发的异常？

我认为你仍然需要捕捉异常，但是在将它们发送回客户端时将它们包含在错误中。请参阅：http://msdn.microsoft.com/en-us/library/ms752208.aspx – Davio

我发现问题的原因 - 异常是在我的Web服务中的工作线程（System.Threading.ThreadPool.QueueUserWorkItem）中引发的，所以当然没有被处理。通过添加异常处理程序并记录到工作线程来修复。

它解决了您的特定情况，但您不期望的任何其他异常都可能导致相同的问题。 –
