net json 文件怎么打开

    public string GetFileJson(string filepath)
    {
        string json = string.Empty;
        using (FileStream fs = new FileStream(filepath, FileMode.Open, System.IO.FileAccess.Read, FileShare.ReadWrite))
        {
            using (StreamReader sr = new StreamReader(fs, Encoding.GetEncoding("gb2312")))
            {
                json = sr.ReadToEnd().ToString();
            }
        }
        return json;
    }

第三、返回.json文件

    public ActionResult GridPageListJson()
    {
        try
        {
            string filepath = Server.MapPath("~/Views/OrderInfoKJ/json1.json");
            string json = GetFileJson(filepath);
            return Content(json);
        }
        catch (Exception ex)
        {
            return null;
        }
    }

第四、展示.json文件
