I got a path from the jquery code URL.createObjectURL([0]); 

It returns something like this : blob:http%3A/localhost%3A59105/f7dae0f7-088f-48cf-b446-eeda0bf23705 

I tried to save this file like 

byte[] data;
    using (WebClient client = new WebClient())
        data =client.DownloadData("blob:http%3A/localhost%3A59105/f7dae0f7-088f-48cf-b446-eeda0bf23705");
    File.WriteAllBytes(@"~/a.jpg", data);

But it gives an error about the code above: 

  The URI prefix is not recognized.

How exactly I can copy this file? 

Thanks for your suggestions.

    1.Create simple GET method 

    public ActionResult GetFile(){
      return View();

    2. Create View with @Html.BeginForm helper 

    @using (Html.BeginForm("GetFile","YourController", FormMethod.Post, { enctype = "multipart/form-data" }))
    <input type="file" id="fileup" name="file"/>
    <input type="submit" value="Send">

    Rembember to use name attribute and overloaded version of Html.BeginForm() 

    3.Get data in Backend 

    public ActionResult GetFile(HttpPostedFileBase file)
      if (file != null && file.ContentLength > 0)
         var fileName =Path.GetFileName(file.FileName);
         var filePath =Path.Combine(Server.MapPath("~/Temp/"), fileName);
      return RedirectToAction("Success");

    Name in html attribute must have same name as HttpPostedFileBase.
