WCF拋出FaultException，客戶端捕獲異常但丟失所有信息

-1

我正在從客戶端向WCF服務進行異步調用。該服務拋出FaultException異常。當我在我的Client「Completed」事件處理程序中捕獲異常時，它捕獲異常，但丟失了有關它的所有信息。我所得到的是一個泛型類型的異常，帶有此錯誤消息：「CommunicationException：遠程服務器返回錯誤：NotFound」）。我有includeExceptionDetailInFaults設置爲true。WCF拋出FaultException，客戶端捕獲異常但丟失所有信息

爲什麼我不能捕捉FaultException？

謝謝你的幫助。

下面是相關代碼：

WCF服務代碼

[WebMethod] 
    [FaultContract(typeof(DivideByZeroException))] 
    public int CountResults(FilterArgs args) 
    { 
     ... 
    DivideByZeroException divByZero = new DivideByZeroException(); 
    throw new FaultException<DivideByZeroException>(divByZero);

客戶端代碼

void seasClient_CountResultsCompleted(object sender, CountResultsCompletedEventArgs e) 
    { 
     try 
     { 
      ... 
     } 
     catch (FaultException ex) 
     { 
      MessageBox.Show("FaultException" + ex.Message); 
     } 
     catch (TimeoutException ex) 
     { 
      MessageBox.Show("TimeoutException" + ex.Message); 
     } 
     catch (CommunicationException ex) 
     { 
      MessageBox.Show("CommunicationException" + ex.Message); 
     } 
     catch (Exception ex) 
     { 
      MessageBox.Show("Exception" + ex.Message); 
     }

和我e.Error.ToString（）消息：

您的服務代碼不是WCF i f它正在使用[WebMethod]屬性。這是一個傳統的ASMX服務，它不使用FaultException。如果您無法切換到使用WCF，請查看SoapException類。

謝謝約翰。我顯然是一個新手，我繼承了這個代碼。 – mschu
