Download files in ASP.NET MVC

In this article I am explaining how to download files in ASP.NET MVC from the physical drive of the server.

Open studio 2010 and create a new ASP.NET MVC 3 Web Application project as seen below:

Choose ASPX as the view engine and click OK.

Add a controller and give the name as HomeController.

Add folder (ImageFile) in Solution Explorer, also add two file in that folder i.e. Koala.jpg and Penguins.jpg.

After adding files create a View (Index) as shown below:

<html>

<head runat="server">

    <title>Index</title>

</head>

<body>

    <div>

        <table>

            <tr>

                <td>

                    <img src="../../ImageFile/Koala.jpg" width="300" height="300" />

                </td>

                <td>

                    <img src="../../ImageFile/Penguins.jpg" width="300" height="300" />

                </td>

            </tr>

            <tr>

                <td align="center">

                    <a href="/Home/Download/1">Download</a><br />

                </td>

                <td align="center">

                    <a href="/Home/Download/2">Download</a>

                </td>

            </tr>

        </table>

    </div>

</body>

</html>

 

Next you have to create an Action method in a controller that returns the file according to id passed to the method. Here if the id passed is as 1 then Koala.jpg file will return and if 2 are passed it will return Penguins.jpg

using System;

using System.Web.Mvc;

 

namespace DownloadDemo.Controllers

{

    public class HomeController : Controller

    {

        public ActionResult Index()

        {

            return View();

        }

        public FilePathResult Download(int id)

        {

            string fileName = "";

            if (id == 1)

                fileName = "Koala.jpg";

            if (id == 2)

                fileName = "Penguins.jpg";

            string path = AppDomain.CurrentDomain.BaseDirectory + "ImageFile/";

            return File(path + fileName, "image/jpg", fileName);

        }

    }

}

 

After creating a Controller method the image is displayed on the page as follows:
