 JS

function save()
    {
        layer.load(2);
         var requestid = @Model.mrequest.RequestID;
        $("#form1").ajaxSubmit({
            url: "@Url.Action("2", "1")",
            type: "post",
            data: { "requestid": requestid },
            success: function (data) {
                if (data.Success) {
                    setTimeout(function () {
                        layer.closeAll('loading');
                         layer.confirm(data.Message, {
                            btn: ['返回列表', '留在此页'], //按钮
                            title: data.Message
                        }, function (index) {
                            layer.close(index);
                            window.location.href = "@Url.Content(" /Request/Index")";
                            }, function (index) {
                                location.replace(location.href);
                        })
                    })
                } else {
                    layer.msg(data.Message, { time: 3000 });
                }
            }
        });
    }

 [HttpPost]
        public ActionResult HSend(HttpPostedFileBase file, int requestid)
        {
            ServiceResult res = new ServiceResult();
            try
            {
                
 
                string text = ConfigurationManager.AppSettings["LocalFolder"];

                //上传的文件保存
                if (!Directory.Exists("路径")
                {
                    Directory.CreateDirectory("路径");
                }

                
                //上传文件的路径以及名
                string text2 = 路径 + .ToString() + ".pdf";

 
                if (!System.IO.File.Exists(text2))
                {
                    try
                    {
                        file.SaveAs(text2);
                    }
                    catch(Exception e)
                    {
                        res.Success = false;
                        res.Message = e.Message;
                        return base.Json(res);
                    }
                }
              catch (Exception e)
            {
                res.Success = false;
                res.Message =e.Message;
                return base.Json(res);
            } 
        }

 最后 如果上传大文件不成功 在web.config

  <httpRuntime targetFramework="4.6.1"  maxRequestLength="500000000" executionTimeout="36000"/>

 <security>
      <requestFiltering>
        <!--500MB-->
        <requestLimits maxAllowedContentLength="500000000" />
      </requestFiltering>
    </security>
