mvc控制器返回操作结果封装

实体类

 public class AjaxResult
    {
        /// <summary>
        /// 获取 Ajax操作结果类型
        /// </summary>
        public ResultType type { get; set; }

        /// <summary>
        /// 获取 Ajax操作结果编码
        /// </summary>
        public int errorcode { get; set; }

        /// <summary>
        /// 获取 消息内容
        /// </summary>
        public string message { get; set; }

        /// <summary>
        /// 获取 返回数据
        /// </summary>
        public object resultdata { get; set; }
    }
    /// <summary>
    /// 表示 ajax 操作结果类型的枚举
    /// </summary>
    public enum ResultType
    {
        /// <summary>
        /// 消息结果类型
        /// </summary>
        info = 0,

        /// <summary>
        /// 成功结果类型
        /// </summary>
        success = 1,

        /// <summary>
        /// 警告结果类型
        /// </summary>
        warning = 2,

        /// <summary>
        /// 异常结果类型
        /// </summary>
        error = 3
    }

josn的封装

/// <summary>
    /// Json操作
    /// </summary>
    public static class Json
    {
        public static object ToJson(this string Json)
        {
            return Json == null ? null : JsonConvert.DeserializeObject(Json);
        }
        public static string ToJson(this object obj)
        {
            var timeConverter = new IsoDateTimeConverter { DateTimeFormat = "yyyy-MM-dd HH:mm:ss" };
            return JsonConvert.SerializeObject(obj, timeConverter);
        }
        public static string ToJson(this object obj, string datetimeformats)
        {
            var timeConverter = new IsoDateTimeConverter { DateTimeFormat = datetimeformats };
            return JsonConvert.SerializeObject(obj, timeConverter);
        }
        public static T ToObject<T>(this string Json)
        {
            return Json == null ? default(T) : JsonConvert.DeserializeObject<T>(Json);
        }
        public static List<T> ToList<T>(this string Json)
        {
            return Json == null ? null : JsonConvert.DeserializeObject<List<T>>(Json);
        }
        public static DataTable ToTable(this string Json)
        {
            return Json == null ? null : JsonConvert.DeserializeObject<DataTable>(Json);
        }
        public static JObject ToJObject(this string Json)
        {
            return Json == null ? JObject.Parse("{}") : JObject.Parse(Json.Replace("&nbsp;", ""));
        }
    }

调用实例

        /// <summary>
        /// 登录
        /// </summary>
        [HttpPost]
        public ActionResult LoginMvc(op_users login)
        {
           //代码
            return Content(new AjaxResult { type = ResultType.success, message = "登陆成功" }.ToJson());
        }
