基本异常处理模式：

（1）异常开关：IncludeExceptionDetailInFaults。

　　使用方式：配置的方式和应用自定义特性（Custom Attribute）的方式。

　　配置方式：

   1: <?xml version="1.0" encoding="utf-8" ?>
   2: <configuration>  
   3:     <system.serviceModel> 
   4:         <behaviors>
   5:             <serviceBehaviors>
   6:                 <behavior name="serviceDebuBehavior">
   7:                     <serviceDebug includeExceptionDetailInFaults="true" />
   8:                 </behavior>
   9:             </serviceBehaviors>
  10:         </behaviors>
  11:         <services>
  12:             <service behaviorConfiguration="serviceDebuBehavior" name="Artech.WcfServices.Services.CalculatorService">
  13:                 <endpoint address="http://127.0.0.1:3721/calculatorservice" binding="wsHttpBinding"                    contract="Artech.WcfServices.Contracts.ICalculator" />
  14:             </service>
  15:         </services>
  16: </system.serviceModel>
  17: </configuration>

自定义特性的

   1: using Artech.WcfServices.Contracts;
   2: using System.ServiceModel;
   3: namespace Artech.WcfServices.Services
   4: {
   5:     [ServiceBehavior(IncludeExceptionDetailInFaults = true)]
   6:     public class CalculatorService : ICalculator
   7:     {
   8:         //省略服务成员
   9: }
  10: }

FaultException<TDetail>与FaultException的关系

   1: [Serializable]
   2: public class FaultException<TDetail> : FaultException
   3: {    
   4:      // 其他成员
   5:     public FaultException(TDetail detail);  
   6:     public TDetail Detail { get; }
   7: }

System.ServiceModel.ExceptionDetail与System.Exception设计类似

1: [DataContract]
   2: public class ExceptionDetail
   3: {
   4:     // 其他成员
   5:     public ExceptionDetail(Exception exception);
   6:  
   7:     [DataMember]
   8:     public string HelpLink { get; private set; }
   9:     [DataMember]
  10:     public ExceptionDetail InnerException { get; private set; }
  11:     [DataMember]
  12:     public string Message { get; private set; }
  13:     [DataMember]
  14:     public string StackTrace { get; private set; }
  15:     [DataMember]
  16: public string Type { get; private set; }
  17: }
