你好我試圖讓Ierrorhandler爲小時現在的工作和即時通訊相當堅持:) 我已經得到了最結果​​本指南

，但我不能把它與我的opertations /功能

      { 
       try 
       { 
        host.Open(); 
        Console.WriteLine("Host open. Press any key to <EXIT>"); 
        Console.ReadLine(); 
        host.Close(); 
       } 
       catch (Exception e) 
       { 
        Console.WriteLine(Environment.NewLine + e.Message); 
        host.Close();

確定，所以，如果我把一些console.writeLine內

公共類GlobalExceptionHandlerBehaviourAttribute：屬性，IServiceBehavior接口 功能我看到他們在運行時我啓動程序。但我不能得到與我的函數指導工作的例子拋出一個異常，並得到一個由我的IErrorhandler捕獲的。

我已經嘗試了其他函數內的一些異常，並沒有發生與我的IErrorhandler。

但一個例外抓到它，我迄今發現它時，我加入我的服務Wcftestclient，然後停止調試，並在我的IService.cs刪除[OperationContract的]，然後重新開始，並嘗試運行該功能沒有刷新，該異常被IErrorhandler捕獲

所以我的問題是爲什麼我不能捕捉函數內的異常？ 非常感謝你的答案。 C（：

請問FaultContractAttribute足以滿足你正在嘗試做 看一看在MSDN文檔的例子 http://msdn.microsoft.com/en-us/library/system.servicemodel.faultcontractattribute.aspx 聽起來類似於您正在嘗試做的，用更少的複雜性？比定製服務行爲。

FaultContracts跨進程/機器使用WCF時，因爲消費者並不一定是.NET客戶端有例外的等價物。
