MVC 4 Razor File Upload

by

The Upload method’s HttpPostedFileBase parameter must have the same name as the the file input.

So just change the input to this:

<input type="file" name="file" />

Also, you could find the files in Request.Files:

[HttpPost]
public ActionResult Upload()
{
     if (Request.Files.Count > 0)
     {
         var file = Request.Files[0];

         if (file != null && file.ContentLength > 0)
         {
            var fileName = Path.GetFileName(file.FileName);
            var path = Path.Combine(Server.MapPath("~/Images/"), fileName);
            file.SaveAs(path);
         }
     }

     return RedirectToAction("UploadDocument");
 }
