Upload and read text file in

In this article I am going to explain how to upload and read text file in

I want to upload and read the text file. Text file will be save to folder and content of text file will be displayed in textbox.

HTML markup:
<html xmlns="">
<head runat="server">
    <form id="form1" runat="server">
            <tr><td>Upload File :</td><td><asp:FileUpload ID="FileUpload1" runat="server" accept=".txt" /></td></tr>
             <tr><td></td><td><asp:Button ID="Button1" runat="server" Text="Button" /></td></tr>
             <tr><td colspan="2"></td></tr>
             <tr><td colspan="2"><asp:TextBox ID="txtarea" runat="server" TextMode="MultiLine" Width="600px" Height="500px" Visible="false"></asp:TextBox></td></tr>

Add namespace
C# Code:
using System.IO; Code:
Imports System.IO

On button click write the below given code

C# Code:
protected void Button1_Click(object sender, EventArgs e)
            string filepath = Server.MapPath("~/upload") + Path.GetFileName(FileUpload1.FileName);
            string text = File.ReadAllText(filepath);
            txtarea.Visible = true;
            txtarea.Text = text;
        catch (Exception ex) { }
    } Code:
Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
           Dim filepath As String = Server.MapPath("~/upload ") + Path.GetFileName(FileUpload1.FileName)
            Dim text As String = File.ReadAllText(filepath)
            txtarea.Visible = True
            txtarea.Text = text
        Catch ex As Exception
        End Try
    End Sub    End Sub
