In ASP.NET 2.0, the FileUpload control enables users to upload file from your web pages. The FileUpload control consists of a text box and a browse button. Clicking on the button allow users to select a file on the client and upload it to the server.
Let us start how to upload multiple file on a single button click. Follow these 2 steps
Step 1: Drag and drop multiple (in my case four) FileUpload controls on to 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 name space
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)
{
}
}
}
Add a tag in 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
