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.

Syntax : Directory.CreateDirectory(DirPath)

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.

Syntax : Directory.Exists(DirPath) as Boolean

DirPath : The name of the directory

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.

Syntax : Move(sourceDirName,destDirName)

sourceDirName : The source directory we want to move.

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

Syntax : Delete(DirPath)

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 ")
        Else
            'create the directory testDir1
            Directory.CreateDirectory("c:\testDir1")
            MsgBox("testDir1 created ! ")
            'create the directory testDir2
            Directory.CreateDirectory("c:\testDir1\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
            Directory.Delete("c:\testDir1")
            MsgBox("testDir1 deleted ")
        End If
    End Sub
End Class

When you executing this program you can see , first it create directory testDir1 and then testDir2 is creating inside testDir1 , Next the program move the testDir2 to testDir . Finally it delete the directory testDir1. After the execution you can see testDir in c:\
