In this article I will explain with an example, how to upload files using Request.Files collection in ASP.Net MVC.
Note: For beginners in ASP.Net MVC, please refer my article ASP.Net MVC Hello World Tutorial with Sample Program example.
You will need to import the following namespace.
using System.IO;
The Controller consists of two Action methods.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
Action method for handling POST operation
This Action method handles the operation of uploading of Files. The File is fetched from the Request.Files Form Collection using the name of the HTML FileUpload element.
Then a check is performed whether Directory (Folder) exists if not then the Directory (Folder) is created and then the file is saved to the Directory (Folder).
Finally, a message is displayed to the user using TempData. For more details on displaying message using TempData, please refer my article ASP.Net MVC: TempData Tutorial with example.
public class HomeController : Controller
    // GET: Home
    public ActionResult Index()
        return View();
    public ActionResult Upload()
        if (Request.Files.Count > 0)
            HttpPostedFileBase postedFile = Request.Files["postedFile"];
            string path = Server.MapPath("~/Uploads/");
            if (!Directory.Exists(path))
            postedFile.SaveAs(path + Path.GetFileName(postedFile.FileName));
            TempData["Message"] = "File uploaded successfully.";
        return RedirectToAction("Index");
The following View consists of an HTML FileUpload element, a Submit Button and a SPAN element for displaying Message enclosed in a Form element.
The HTML Form has been created using the Html.BeginForm method which accepts the following parameters.
ActionName – Name of the Action. In this case the name is Upload.
ControllerName – Name of the Controller. In this case the name is Home.
FormMethod – It specifies the Form Method i.e. GET or POST. In this case it will be set to POST.
HtmlAttributes – This array allows to specify the additional Form Attributes. Here we need to specify enctype = “multipart/form-data” which is necessary for uploading Files.
    Layout = null;
<!DOCTYPE html>
    <meta name="viewport" content="width=device-width" />
        @using (Html.BeginForm("Upload", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
            <span>Select File:</span>
            <input type="file" name="postedFile" />
            <input type="submit" value="Upload" />
            <span style="color:green">@TempData["Message"]</span>
