I got a path from the jquery code URL.createObjectURL(event.target.files[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.

    Re: Asp.NET temporary file saving

    1.Create simple GET method

     

    [HttpGet]

    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

     

    [HttpPost]

    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);

         file.SaveAs(path);

      }

     

      return RedirectToAction("Success");

    }

    Name in html attribute must have same name as HttpPostedFileBase.
