后台(MVC控制器)

public JsonResult UploadAppraisal(HttpPostedFileBase fileData, string resultPath)

        {

            if (fileData != null)

            {

                try

                {

                    // 文件上传后的保存路径

                    string filePath = Server.MapPath("../Upload/temp");

                    string Size = HumanReadableFilesize(fileData.ContentLength);

                    if (!Directory.Exists(filePath))

                    {

                        Directory.CreateDirectory(filePath);

                    }

                    string fileNames = Path.GetFileName(fileData.FileName);// 原始文件名称

                    string fileName = Regex.Match(fileNames, @".*?(?=[.])").Value;//去掉后缀名字的文件名字

                    string fileExtension = Path.GetExtension(fileNames); // 文件扩展名

                    string saveName = Guid.NewGuid().ToString() + fileExtension; // 保存文件名称

                    string path = filePath + "\\" + saveName;

                    string Filesize = HumanReadableFilesize(fileData.ContentLength);//字节大小

                    string FileDw = HumanReadableFile(fileData.ContentLength);//字节单位

                    fileData.SaveAs(path);

                    return Json(new

                    { Success = true, FileName = saveName});

                }

                catch (Exception ex)

                {

                    return Json(new

                    { Success = false, Message = ex.Message }, JsonRequestBehavior.AllowGet);

                }

            }

            else

            {

                return Json(new

                { Success = false, Message = "请选择要上传的文件！" }, JsonRequestBehavior.AllowGet);

            }

        }

一个页面有多个上传控件

修改jquery.uploadify.js、jquery.uploadify.min.js

   var mydate = new Date();

        this.movieName = "SWFUpload_" + mydate.getTime().toString();

上传大文件(Web.config)

Web.config添加一下代码

<system.web>

    <compilation debug="true" targetFramework="4.5" />

    <!--maxRequestLength就是文件的最大字符数，最大值不能超过2个G左右，executionTimeout是超时时间-->

    <httpRuntime targetFramework="4.5" maxRequestLength="" executionTimeout="" />

  </system.web>

<system.webServer>

    <security>

      <requestFiltering>

        <!--修改服务器允许最大长度-->

        <requestLimits maxAllowedContentLength=""/>

      </requestFiltering>

    </security>

  </system.webServer>
