Uploading Multiple Files in ASP.NET 2.0

In ASP.NET 2.0, the FileUpload control enables users to upload files from your web pages. The FileUpload control consists of a text box and a browse button. Clicking on the button allows users to select a file on the client and upload it to the server.

Let us start with how to upload multiple files with a single button click. Follow these 2 steps.

Step 1. Drag and drop multiple (in my case four) FileUpload controls onto the designer.

Step 2. Drop a Button control and rename it to "Upload".

This is the aspx code.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!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>To Upload Multiple File in ASP.NET 2.0</title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:FileUpload ID="FileUpload1" runat="server" /><br />
            <asp:FileUpload ID="FileUpload2" runat="server" /><br />
            <asp:FileUpload ID="FileUpload3" runat="server" /><br />
            <asp:FileUpload ID="FileUpload4" runat="server" /><br />
            <asp:Button ID="btnUpload" runat="server" Text="Upload" OnClick="btnUpload_Click1" /><br />
            <asp:Label ID="Label1" runat="server"></asp:Label>
        </div>
    </form>
</body>
</html>

This is the aspx.cs code.

Firstly add a namespace

using System.IO;

Now the code is.

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
    protected void btnUpload_Click1(object sender, EventArgs e)
    {
        try
        {
            // To Upload Multiple Files on Single Click
            HttpFileCollection hfc = Request.Files;
            for (int i = 0; i < hfc.Count; i++)
            {
                HttpPostedFile hpf = hfc[i];

                if (hpf.ContentLength > 0)
                {
                    hpf.SaveAs(Server.MapPath("MyFiles") + "\\" + Path.GetFileName(hpf.FileName));
                }
            }
        }
        catch (Exception ex)
        {
            // Handle exception (optional)
        }
    }
}

Add a tag on the web. config file.

<httpRuntime
    executionTimeout="200"
    maxRequestLength="8192"
    requestLengthDiskThreshold="256"
    useFullyQualifiedRedirectUrl="false"
    minFreeThreads="8"
    minLocalRequestFreeThreads="4"
    appRequestQueueLimit="5000"
    enableKernelOutputCache="true"
    enableVersionHeader="true"
    requireRootedSaveAsPath="true"
    enable="true"
    shutdownTimeout="90"
    delayNotificationTimeout="5"
    waitChangeNotification="0"
    maxWaitChangeNotification="0"
    enableHeaderChecking="true"
    sendCacheControlHeader="true"
    apartmentThreading="false" />

When you run the application then.
