化零为整WCF - 异常处理(Exception、FaultException、FaultException

【IT168技术文档】

  WCF(Windows Communication Foundation) - 异常处理：一般Exception的处理，FaultException和FaultException<T>的抛出和处理，使用IErrorHandler处理异常。
  服务IHello.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
namespace WCF.ServiceLib.Exception
{
/**//// <summary>
/// IHello接口
/// </summary>
    [ServiceContract]
public interface IHello
{
/**//// <summary>
/// 抛出Exception异常
/// </summary>
        [OperationContract]
void HelloException();
/**//// <summary>
/// 抛出FaultException异常
/// </summary>
        [OperationContract]
void HelloFaultException();
/**//// <summary>
/// 抛出FaultException<T>异常
/// </summary>
        [OperationContract]
[FaultContract(typeof(FaultMessage))]
void HelloFaultExceptionGeneric();
/**//// <summary>
/// IErrorHandler处理异常
/// </summary>
        [OperationContract]
void HelloIErrorHandler();
}
}

  FaultMessage.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Runtime.Serialization;
namespace WCF.ServiceLib.Exception
{
/**//// <summary>
/// 错误信息实体类（用于错误契约FaultContract）
/// </summary>
    [DataContract]
public class FaultMessage
{
/**//// <summary>
/// 错误信息
/// </summary>
        [DataMember]
public string Message { get; set; }
/**//// <summary>
/// 错误代码
/// </summary>
        [DataMember]
public int ErrorCode { get; set; }
}
}
