File upload in ASP.Net

Upload a file in ASP.Net
File uploading is very necessary thing to develop a dynamic website. By default ASP.Net support file upload upto 4MB of size. If you want to upload more then you have to configure web.config  file. In next post i will explain how to upload large file in ASP.NET.  

Add the content within an ASP.Net page

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="" >
<head runat="server">
    <title>Untitled Page</title>
    <form id="form1" runat="server">
        <asp:FileUpload ID="FileUpload1" runat="server" />
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Upload" /></div>

One file upload control and one button will apear in page. Now write the folowing code in button’s click event. It will upload a file into D: directory.

protected void Button1_Click(object sender, EventArgs e)
        if (FileUpload1.HasFile)
                FileUpload1.SaveAs("D:\\" + FileUpload1.FileName);
            catch (Exception ex)
                Response.Write(“Problem in file upload” + ex.Message);
