How to save the data in notepad in VB.NET or C# windows forms and how to create notepad file or how to append the data to existing notepad file in VB.NET or C# windows forms.

                                        Hi friends, in this article I will explain about how to save the data in notepad in VB.NET or C# windows forms and how to create notepad file or how to append the data to existing notepad file in VB.NET or C# windows forms.
First of all, take one windows form.
File—New—Project or Ctrl+Shift+N
Then take the 2 textboxes , 2 labels and 1 button in the below figure.


Then write the following code in the button click.

VB.NET


Imports System.IO

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim swriter As StreamWriter
        swriter = File.AppendText("c:\temp\myfile.txt")
        swriter.WriteLine(TextBox1.Text & " " & TextBox2.Text)
        swriter.Close()
    End Sub
End Class



C#.NET

using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using System.IO;

Public Class Form1
{

     private void Button1_Click(System.Object sender, System.EventArgs e)
     {
          StreamWriter swriter = null;
          swriter = File.AppendText("c:\\temp\\myfile.txt");
          swriter.WriteLine(TextBox1.Text + " " + TextBox2.Text);
          swriter.Close();
     }
}

We have imports the System.IO namespace otherwise it will raise error.
