for loop in VB.Net

Example

Module loops Sub Main() Dim a As Byte ' for loop execution For a = 10 To 20 Console.WriteLine("value of a: {0}", a) Next Console.ReadLine() End Sub End Module

When the above code is compiled and executed, it produces the following result −

value of a: 10 value of a: 11 value of a: 12 value of a: 13 value of a: 14 value of a: 15 value of a: 16 value of a: 17 value of a: 18 value of a: 19 value of a: 20

If you want to use a step size of 2, for example, you need to display only even numbers, between 10 and 20 −

Module loops Sub Main() Dim a As Byte ' for loop execution For a = 10 To 20 Step 2 Console.WriteLine("value of a: {0}", a) Next Console.ReadLine() End Sub End Module

When the above code is compiled and executed, it produces the following result −

value of a: 10 value of a: 12 value of a: 14 value of a: 16 value of a: 18 value of a: 20 vb.net_loops.htm Print Page Previous Next Advertisements
