VB.Net Tutorial/Class Module/Const

Define Integer constant

Module Module1
    Sub Main( )
       Const FreezingPoint As Integer = 32 
       Const BoilingPoint As Integer = 212
       System.Console.WriteLine("Freezing point of water: {0}", FreezingPoint)
       System.Console.WriteLine("Boiling point of water: {0}", BoilingPoint)
    End Sub
 End Module

Freezing point of water: 32
Boiling point of water: 212

Use Const to define constant

Module Module1
    Sub Main()
        Const Pi = "3.1415926535"
        Console.WriteLine(Pi)
    End Sub
End Module

3.1415926535
