在控制器中：

In controller :

public ActionResult ImageUpload()
       {
           return View();
       }
       [HttpPost]
       public string ImageUpload(HttpPostedFileBase FileData)
       {

           FileData = Request.Files[0];
           if (FileData.ContentLength > 0)
           {
               var fileName = Path.GetFileName(FileData.FileName);
               var path = Path.Combine(Server.MapPath("~/Content"), fileName);
               FileData.SaveAs(path);
           }

           return "Files was uploaded successfully!";
       }

（ document ） .ready（ function （）{

(document).ready(function () {

（ #uploader）。pluploadQueue（{
// 常规设置
运行时：' html5，html4，gears，flash，silverlight'，
url：' @ Url.Action（UploadImage）'，

unique_names： true ，

// 如果我们可以 $ b，请在客户端调整图片大小$ b调整大小：{width： 320 ，身高： 340 ，质量： 90 }，

// Silverlight设置
