In this article, I will explore how to upload a file using ASP.NET MVC. Since the MVC framework does not use server controls, it will be interesting to see how file upload works in MVC.


In this article, I will explore how to upload a file using ASP.NET MVC. Since the MVC framework does not use server controls, it will be interesting to see how file upload works in MVC.

Using the code

Here is my view that renders a form for uploading files:

<%@ Page Title="" Language="C#" 


  Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
     <% using (Html.BeginForm("FileUpload", "FileUpload", 
                    FormMethod.Post, new { enctype = "multipart/form-data" }))
        <input name="uploadFile" type="file" />
        <input type="submit" value="Upload File" />
<%} %>

Now, I will write a controller for file upload, and here is my FileUploadController.cs:

public class FileUploadController : Controller
    public ActionResult FileUpload()
        return View();

    public ActionResult FileUpload(HttpPostedFileBase uploadFile)
        if (uploadFile.ContentLength > 0)
            string filePath = Path.Combine(HttpContext.Server.MapPath("../Uploads"), 
        return View();

One thing to note is that the controller has two overloaded methods of FileUpload. The first, ActionResult FileUpload(), is just to render the form and the method that is attributed with [AcceptVerbs(HttpVerbs.Post)] will upload the file. Here is the output form for uploading files:


The MVC framework does not use server controls, so we built an HTTP File Upload method with ASP.NET MVC.

I have a button on View page, which will open a dialog(modal) using JQuery script. This dialog contains few fields and the input type 'file' to select the file from the machine.

As this is a dialog box i am using Ajax call to post the data back to my MVC application(contoller/action)
Looks like Ajax calls wont deal with File Upload.

How to do File Upload in Jquery Dialog box in ASP.NET MVC?

Any help in achieving the same would be appreciated.
