发个服务端包裹返回值的Response类和用法

Response类：

using System;
using System.Collections.Generic;
using System.Runtime.Serialization;

namespace ConsoleApplication1
{
    [DataContract]
    [Serializable]
    public class Response
    {
        [DataMember]
        public string MessageKey { get; set; }
        [DataMember]
        public bool IsSuccess { get; set; }
    }
    [DataContract]
    [Serializable]
    public class Response<T> : Response
    {
        [DataMember]
        public T Item { get; set; }
    }
    [DataContract]
    [Serializable]
    public class ListResponse<T> : Response
    {
        [DataMember]
        public List<T> Items { get; set; }
    }
}

用法：

 public Response<List<xxxBE>> Getxxx(int a, Guid b)
        {
            //············
            //············
            Response<List<xxxBE>> xxxBEResponseList = new Response<List<xxxBE>>();
            List<xxxBE> xxxBEList = new List<xxxBE>();
            try
            {
                //············
                //············
                foreach (var item in XXOO)
                {
                    //············
                    //············
                    xxxBE xxx = new xxxBE();
                    //············
                    //············
                    xxxBEList.Add(xxx);
                }
                xxxBEResponseList.MessageKey = "Get XXX Succeed";
                xxxBEResponseList.Item = xxxBEList;
                xxxBEResponseList.IsSuccess = true;
            }
            catch (Exception e)
            {
                xxxBEResponseList.MessageKey = "Get XXX Failed";
                xxxBEResponseList.Item = null;
                xxxBEResponseList.IsSuccess = false;
            }
            return xxxBEResponseList;
        }
