Visual Basic comes with a lot of predefined code snippets for selected actions, and you can insert these snippets into your code as needed. Let’s say you want to insert the statements for writing some text to a file, but you have no idea how to access files. In the following example we will print all drivers of our computer.

Example

Imports System.IO

Module Module1

    Sub Main()

        For Each drive As DriveInfo In My.Computer.FileSystem.Drives
            Console.WriteLine(drive.Name) 'printing drive names
        Next
        Console.ReadLine() ' waiting for one character to enter from user to pause screen
    End Sub

End Module

Output (on my computer)

C:\
D:\
E:\
F:\
G:\
