How to VB.NET Directory operations

Using Directory class , we can create , delete , move etc. operations in VB.NET. Because of the static nature of Directory class , we do not have to instantiate the class. We can call the methods in the class directly from the Directory class.

How to create a directory ?

In order to create a new directory , we can call CreateDirectory directly from Directory class.

  1. Syntax : Directory.CreateDirectory(DirPath)
  2. DirPath : The name of the new directory

VB.NET : Directory.CreateDirectory("c:\testdir")

How to check a directory exist or not ?

Before we creating a directory , we usually check that directory exist or not. For that we are using the Exists method in the Directory class.

  1. DirPath : The name of the directory
  2. Boolean : Returns true or false , if directory exist it Returns true , else it Returns false

VB.NET : Directory.Exists("c:\testdir")

How to move a Directory ?

If we want to move a directory and its contents from one location to another , we can use the Move method in the Directory class.

  1. sourceDirName : The source directory we want to move.
  2. destDirName : The destinations directory name.

VB.NET : Directory.Move("c:\testdir1\testdir2", "c:\testdir")

How to delete a Directory ?

When we want to delete a directory we can use the Delete method in the Directory class.

  1. DirPath : The Directory we want to delete.

VB.NET : Directory.Delete("c:\testdir1")

The following VB.NET source code shows these operations :

Imports System.IO
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object,_ 
	ByVal e As System.EventArgs) Handles Button1.Click
        If Directory.Exists("c:\testDir1") Then
            'shows message if testdir1 exist
            MsgBox("Directory 'testDir' Exist ")
            'create the directory testDir1
            MsgBox("testDir1 created ! ")
            'create the directory testDir2
            MsgBox("testDir2 created ! ")
            'move the directory testDir2 as testDir in c:            Directory.Move("c:\testDir1\testDir2", "c:\testDir")
            MsgBox("testDir2 moved ")
            'delete the directory testDir1
            MsgBox("testDir1 deleted ")
        End If
    End Sub
End Class
