Now add some text in file.
Now add the below code
into the page.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm17.aspx.cs" Inherits="WebApplication2.WebForm17"
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD

<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Click To Read the File"
onclick="Button1_Click" /><br />
<asp:Label ID="lblMessage" runat="server" style="color: #FF0000"></asp:Label>
</div>
</form>
</body>
</html>

In above I have taken a button control and a label. When user click on button he will be able to read the text and display into the label control.
Now here is the code to
read the file.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
namespace WebApplication2
{
public partial class WebForm17 : System.Web.UI.Page
{
protected
void Page_Load(object
sender, EventArgs e)
{
}
protected
void Button1_Click(object
sender, EventArgs e)
{
int
lineCounter = 0;
string
finalStringText = "";
string
datastring;
StreamReader
textfile = new StreamReader(Server.MapPath(@"TextFile\TextFile1.txt"));
while
((datastring = textfile.ReadLine()) != null)
{
finalStringText =
finalStringText + datastring;
lineCounter++;
}
lblMessage.Text =
finalStringText;
}
}
}

In above code I have first locate the file and then read the
file to display on label control. Now we have done run the application to check
the output.
