How to implement Ajax file upload with fine uploader+asp.net MVC

Fine Uploader (http://fineuploader.com/) is a Javascript component that implements Ajax upload files.

This project attempts to achieve a user-friendly file-uploading experience over the web. It ' s built as a Javascript plugin for developers looking to incorporate into file-uploading their.

Fine Uploader does not rely on jQuery, which means it does not reference jquery.js, and can be used normally. It also provides a jquery wrapper that can be easily integrated with jquery.

The example code in this blog post is the Fine Uploader jQuery wrapper. Look at the sample code below:

Web Front-End Implementation

Server asp.net MVC Implementation code
 
Fine Uploader's source code uses vb.net to implement a Controller (Uploadcontroller.vb), which we changed to C # code when we used it:
 
Using System;
Using System.Collections.Generic;
Using System.IO;
Using System.Linq;
Using System.Web;
    
Using SYSTEM.WEB.MVC; Namespace CNBlogs.Upload.Web.Controllers {public class Imageuploadercontroller:controller {const int C
    
        Hunksize = 1024 * 1024;
        Public ActionResult Upload () {return View (); Public ActionResult Processupload (string qqfile) {using (var stream = Request.inputstr EAM) {using (var br = new BinaryReader (stream)) {Writest
                Ream (BR, qqfile);
        } return Json (new {success = true}); } private void Writestream (BinaryReader br, String fileName) {byte[] filecontents = new
            Byte[] {};
    
            var buffer = new Byte[chunksize]; while (Br. Basestream.position < Br.
         BASESTREAM.LENGTH-1) {       if (Br. Read (buffer, 0, chunksize) > 0) {filecontents = filecontents.concat (buffer).
                ToArray (); 
                The using (var fs = new FileStream (@ "c:\\temp\\" + DateTime.Now.ToString ("YYYYMMDDHHMMSS") + Path.getextension (FileName).
                    ToLower (), FileMode.Create)) {using (var bw = new BinaryWriter (FS)) { Bw.
                Write (filecontents); }
            }
        }
    }
}
