    [HttpPost]
    public bool GetFileContent()
    {
        string key = Request.Form["key"];
        try
        {

            HttpPostedFileBase file = Request.Files[key];

            if (file == null || file.ContentLength <= 0)
            {
                //文件为空
            }
            else
            {

                //具体业务逻辑代码
            }


        }
        catch (Exception ex)
        {

        }
