How to copy a text file or notepad file or .txt file in VB.NET or C# windows forms..

Hi friends, in this article I will explain about how to copy a text file or notepad file or .txt file.
I already explained in the previous article How to Create, Read, Write, Copy, Move and Delete a Text File or notepad file using C# and VB.NET

Copy the text file:
VB.NET Code:

Imports System.IO
Imports System.Text
Public Class Form2

    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim firstfile As String = "c:\temp\kishore.txt"
        Dim copyfile As String = "c:\temp\kishore1.txt"
        If File.Exists(firstfile) Then
            ' If file already exists in destination, delete it.
            If File.Exists(copyfile) Then
                File.Delete(copyfile)
            End If
            File.Copy(firstfile, copyfile)
        End If
    End Sub
End Class

C# Code:

using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using System.IO;
using System.Text;
Public Class Form2
{

     private void Form2_Load(System.Object sender, System.EventArgs e)
     {
          string firstfile = "c:\\temp\\kishore.txt";
          string copyfile = "c:\\temp\\kishore1.txt";
          if (File.Exists(firstfile)) {
              // If file already exists in destination, delete it.
              if (File.Exists(copyfile)) {
                   File.Delete(copyfile);
              }
              File.Copy(firstfile, copyfile);
          }
     }
    Public Form2()
     {
          Load += Form2_Load;
     }
}
                               When we execute the  above it will copy the firstfile to copy file.If the firstfile(kishore1.txt) is there in the c:\temp location then it will delete the file and create a new file kishore1.txt and copy the data from kishore.txt to kishore1.txt.
