解决Asp.net Mvc返回JsonResult中DateTime类型数据格式问题的方法

在这里做的“小动作”就是红色部分，得到字符串以后，通过正则表达式的方式获得Date(12347838383333)的字符串，然后把它转换为DateTime类型，最后在转为我们想要的格式即可，这个格式可以使用FormateStr属性设置。

剩下的就是使用我们自己定义的JsonResult来替换asp.net mvc默认的JsonResult的问题了，接着从源码中找答案，下面是Controller类的部分代码

protected internal JsonResult Json(object data)
    {
      return this.Json(data, null, null, JsonRequestBehavior.DenyGet);
    }
    
    protected internal JsonResult Json(object data, string contentType)
    {
      return this.Json(data, contentType, null, JsonRequestBehavior.DenyGet);
    }
    
    protected internal JsonResult Json(object data, JsonRequestBehavior behavior)
    {
      return this.Json(data, null, null, behavior);
    }
    
    protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding)
    {
      return this.Json(data, contentType, contentEncoding, JsonRequestBehavior.DenyGet);
    }
    
    protected internal JsonResult Json(object data, string contentType, JsonRequestBehavior behavior)
    {
      return this.Json(data, contentType, null, behavior);
    }
    
    protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding, JsonRequestBehavior behavior)
    {
      return new JsonResult { Data = data, ContentType = contentType, ContentEncoding = contentEncoding, JsonRequestBehavior = behavior };
    }

以上是Controller类来实例化JsonResult的所有代码。我们只需写一个BaseController类，重写最后一个方法即可，然后我们自己的Controller在继承BaseController即可

下面是BaseController类的部分代码，我们为方便自己个性化的需要又定义了两个MyJosn的方法

/// <summary>
    /// 返回JsonResult
    /// </summary>
    /// <param name="data">数据</param>
    /// <param name="contentType">内容类型</param>
    /// <param name="contentEncoding">内容编码</param>
    /// <param name="behavior">行为</param>
    /// <returns>JsonReuslt</returns>
    protected override JsonResult Json(object data, string contentType, System.Text.Encoding contentEncoding, JsonRequestBehavior behavior)
    {
      return new CustomJsonResult
      {
        Data = data,
        ContentType = contentType,
        ContentEncoding =contentEncoding,
        JsonRequestBehavior = behavior,
        FormateStr = "yyyy-MM-dd HH:mm:ss"
      };
    }

    /// <summary>
    /// 返回JsonResult.24     /// </summary>
    /// <param name="data">数据</param>
    /// <param name="behavior">行为</param>
    /// <param name="format">json中dateTime类型的格式</param>
    /// <returns>Json</returns>
    protected JsonResult MyJson(object data, JsonRequestBehavior behavior,string format)
    {
      return new CustomJsonResult
      {
        Data = data,
        JsonRequestBehavior = behavior,
        FormateStr = format
      };
    }

    /// <summary>
    /// 返回JsonResult42     /// </summary>
    /// <param name="data">数据</param>
    /// <param name="format">数据格式</param>
    /// <returns>Json</returns>
    protected JsonResult MyJson(object data, string format)
    {
      return new CustomJsonResult
      {
        Data = data,
        FormateStr = format
      };
    }
