WCF：如何记录异常？

Question

是否可以记录WCF服务异常？我已经在app.config中添加了。但仍然在wcf日志文件中丢失异常soap消息。在WCF日志文件中可以看到所有其余没有例外的消息。这里是我的代码& app.config。任何指针都非常感谢。

public string GetName(int employeeId) 
{ 
    string _fullName; 

    try 
    { 
     switch (employeeId) 
     { 
      case 1: 
       _fullName = "Dejan Dimitrovski"; 
       break; 
      case 2: 
       _fullName = "John Doe"; 
       break; 
      case 3: 
       _fullName = "Sue Marcus"; 
       break; 
      case 4: 
       throw new Exception("test exception"); 
      default: 
       _fullName = "N/A"; 
       break; 
     } 
    } 
    catch (Exception ex) 
    { 
     throw new FaultException(ex.Message, new FaultCode("Server")); 
    } 
    return _fullName; 
} 

我的app.config

WCF记录所有未处理例外。你已经处理了异常，而是返回了一个错误。

尝试删除try/catch块。我认为你的客户会注意到几乎同样的消息回来，你会记录你的例外。
