In this article I will explain with an example, how to use the jQuery Uploadify plugin to upload multiple files in ASP.Net MVC.
Note: For beginners in ASP.Net MVC, please refer my article ASP.Net MVC Hello World Tutorial with Sample Program example.
The following View consists of an HTML FileUpload element to which the jQuery Uploadify plugin will be applied.
The files required by the jQuery Uploadify plugin are placed inside a folder named Uploadify within the project.
All the necessary Script and CSS files needed for the jQuery Uploadify plugin are inherited in the HEAD section and the jQuery Uploadify plugin is applied to the HTML FileUpload element.
The script property of the jQuery Uploadify plugin is set to the Index Method of the Home Controller.
    <meta name="viewport" content="width=device-width"/>
    <link rel="Stylesheet" type="text/css" href="../Uploadify/uploadify.css"/>
    <script type="text/javascript" src="../Uploadify/jquery-1.3.2.min.js"></script>
    <script type="text/javascript" src="../Uploadify/jquery.uploadify.js"></script>
    <script type="text/javascript">
        $(function () {
                'uploader': '../Uploadify/uploader.swf',
                'cancelImg': '../Uploadify/cancel.png',
                'buttonText': 'Browse Files',
                'script': '/Home/Index/',
                'folder': 'Uploads',
                'fileDesc': 'Image Files',
                'fileExt': '*.jpg;*.jpeg;*.gif;*.png',
                'multi': true,
                'auto': true
        <input type="file" id="postedFile" name="postedFile"/>

You will need to import the following namespace.
using System.IO;
The Action method Index by default supports the GET operation and hence another overridden method for POST operation is created which accepts the parameter which is a collection of type HttpPostedFileBase.
Note: The name of the HttpPostedFileBase parameter must always be FileData as this variable name is used by jQuery Uploadify plugin.
A loop is executed over the HttpPostedFileBase collection and one by one each file is saved to the Directory (Folder).
public class HomeController : Controller
    // GET: Home
    public ActionResult Index()
        return View();
    public ActionResult Index(List<HttpPostedFileBase> FileData)
        string path = Server.MapPath("~/Uploads/");
        foreach (HttpPostedFileBase postedFile in FileData)
            if (postedFile != null)
                string fileName = Path.GetFileName(postedFile.FileName);
                postedFile.SaveAs(path + fileName);
        return View();
