HTTPPostedFileBase always return null in controller

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.

try this one:

var fileCount = Request.Files.Count;
if (fileCount > 0)
{
 for (int i = 0; i < (fileCount); i++)
    { 
        HttpPostedFileBase Yourfile= Request.Files[i] as   HttpPostedFileBase;
        // do whatever with your file
    }
}

if you want to use MVC to upload file you need: - create form and have to set tag: enctype = "multipart/form-data" - create input with name same HttpPostedFileBase in controller
