The following post captures the implementation details for uploading file in ASP.NET MVC. First we need to create HTML form which would receive the file as input:

 @using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
   {
        <in put type="file" name="file" />
        <in put type="submit" value="OK" />
   }

Now, we create action for file upload, below is the code:

[HttpPost]
public ActionResult Index(HttpPostedFileBase file)
{
    // Verify that the user selected a file
    if (file != null && file.ContentLength > 0) 
    {
        var name = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/uploads"), name);
        file.SaveAs(path);
    }

}
