ASP.NET MVC ajax处理 AjaxResult

1、统一ASPNET MVC 对ajax请求响应格式定义，方便前端统一处理ajax结果.

　　1）定义程序返回结果数据格式

/// <summary>
    /// 执行结果
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class RunResult<T>
    {
        /// <summary>
        /// 操作状态
        /// </summary>
        public ResultStatus Status { get; set; }
        /// <summary>
        /// 操作异常
        /// </summary>
        public Exception Exception { get; set; }
        /// <summary>
        /// 数据结果
        /// </summary>
        public T Result { get; set; }
        /// <summary>
        /// 操作消息
        /// </summary>
        public string Message { get; set; }
    }

　　2）定义执行结果状态

/// <summary>
    /// 执行结果
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class RunResult<T>
    {
        /// <summary>
        /// 操作状态
        /// </summary>
        public ResultStatus Status { get; set; }
        /// <summary>
        /// 操作异常
        /// </summary>
        public Exception Exception { get; set; }
        /// <summary>
        /// 数据结果
        /// </summary>
        public T Result { get; set; }
        /// <summary>
        /// 操作消息
        /// </summary>
        public string Message { get; set; }
    }

　  3）返回前端数据格式

  public class AjaxEntity<T>
    {
        [JsonProperty(PropertyName = "Success")]
        public bool Success { get; set; }

        [JsonProperty(PropertyName = "Message")]
        public string Message { get; set; }

        [JsonProperty(PropertyName = "Data")]
        public T Data { get; set; }
    }

　　4）定义asp.net mvc 中 ajax ActionResult

 public class AjaxResult<T> : CustomResult<AjaxEntity<T>>
    {
        private readonly RunResult<T> _runResult;

        public AjaxResult(RunResult<T> runResult)
        {
            _runResult = runResult;
        }

        /// <summary>
        /// 
        /// </summary>
        /// <returns></returns>
        public override AjaxEntity<T> GetObject()
        {
            AjaxEntity<T> entity = new AjaxEntity<T> { Data = _runResult.Result };
            if (_runResult.Result is bool)
            {
                entity.Success = _runResult.Status == ResultStatus.Success && Convert.ToBoolean(_runResult.Result);
            }
            else
            {
                entity.Success = _runResult.Status == ResultStatus.Success;
            }
            entity.Data = _runResult.Result;
            entity.Message = _runResult.Message;
            return entity;
        }
    }
