如何解決'System.ServiceModel.ExceptionDetail'未標記爲可序列化

我有一個ASP.net網站調用的WCF Web服務。在我的web方法中，我故意不捕捉異常，因爲我希望它們能夠由客戶端網站處理。 Web服務純粹是一個內部應用程序，我希望它的行爲像一個標準庫，它希望調用者處理異常。我在服務web.config中有includeExceptionDetailInFaults =「true」。當我的服務拋出一個異常，我得到這個錯誤：如何解決'System.ServiceModel.ExceptionDetail'未標記爲可序列化

如何解決這個問題，所以我的客戶能夠趕上由服務引發的異常？

我認爲你仍然需要捕捉異常，但是在將它們發送回客戶端時將它們包含在錯誤中。請參閱：http://msdn.microsoft.com/en-us/library/ms752208.aspx – Davio

我發現問題的原因 - 異常是在我的Web服務中的工作線程（System.Threading.ThreadPool.QueueUserWorkItem）中引發的，所以當然沒有被處理。通過添加異常處理程序並記錄到工作線程來修復。

它解決了您的特定情況，但您不期望的任何其他異常都可能導致相同的問題。 –
