How to delete the 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 delete the text file or Notepad file or.txt file in VB.NET or C# windows forms.

                              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
                            For deleting the text file we have to using or imports the System.IO namespace. Because the all file classes and methods are located in System.IO namespace. We use the System.IO.File.Delete() method to delete the text file.

Let we know how to delete the text file with the below example.

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 filename As String
        filename = "C:\temp\file.txt"
        If System.IO.File.Exists(filename) = True Then
            System.IO.File.Delete(filename)
            MessageBox.Show("File Deleted Successfully")
        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 filename = null;
          filename = "C:\temp\file.txt";
          if (System.IO.File.Exists(filename) == true) {
              System.IO.File.Delete(filename);
              MessageBox.Show("File Deleted Successfully");
          }
     }
    Public Form2()
     {
          Load += Form2_Load;
     }
}

When we execute the above code the file file.txt located in the temp folder will delete .
