HTTPPostedFileBase always return null in controller

Question

I have checked various answer for this, but none of them works for me, my code in .cshtml is as follows:

Answer 1

You have to add enctype = "multipart/form-data" in form tag.

@using (Html.BeginForm("Action", "Controller", FormMethod.Post, 
                               new { enctype = "multipart/form-data" }))

Try this c# code in controller action

if (Request.Files != null && Request.Files.Count > 0)
{
    HttpPostedFileBase file = Request.Files[0];
    if (file != null && file.ContentLength > 0)
    {
    }
}

You have to retrieve the file.
