Upload file in ASP.NET MVC

Uploading files is a common task in websites. Let’s take a look on how we can upload file in ASP.NET MVC.

View Code

<form enctype="multipart/form-data" method="post">
    <input type="file" name="fileUser" />
    <input type="submit" value="Submit" />
</form>

Controller Code  

[HttpPost]
public ActionResult Index(HttpPostedFileBase fileUser)
{
  if (fileUser != null)
  {
    fileUser.SaveAs(Path.Combine(HttpContext.Server.MapPath("~/UserImages"), fileUser.FileName));
  }
  return View();
}


Points to remember

  •  Form should have attribute enctype="multipart/form-data".
  • File element should have a name attribute.
  • Value of name attribute should be same as which we are receiving in controller. Otherwise it will be null.
