Developing lightweight markup using ASP.NET (or WebForms without forms)

File uploading with ASP.NET HtmlForms

Following up on my previous article about ASP.NET HtmlForms, this sample code illustrates how to handle file uploads. As you can see the usual ASP.NET server side methods work perfectly well even if you don't use an ASP.NET file upload control.

Test.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Test.aspx.cs" Inherits="Test.Test" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
<form action="" enctype="multipart/form-data" method="post"> 
	<input id="fupFile" name="fupFile" type="file" />
	<input type="submit" value="Submit" />
</form> 
</body>
</html>

Test.aspx.cs

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Test
{
	public partial class Test : System.Web.UI.Page
	{
		protected void Page_Load(object sender, EventArgs e)
		{
			if (Request.HttpMethod == "POST")
			{
				HttpPostedFile file = Request.Files["fupFile"];
				if (file != null && file.ContentLength > 0)
				{
					string filename = Path.GetFileName(file.FileName);
					file.SaveAs(Server.MapPath(Path.Combine("~/App_Data/", filename)));
				}
			}
		}
	}
}
