Here we are discussing the decision making in VB.Net using the If Then statements.

The simple if then statement checks whether the condition is true or false, and if the condition is true then the [statement x] will be executed.

Basic Syntax

If condition Then 
 [Statement x]
End If

Example

If (a>0) Then
 console.WriteLine("Postive")
End If

In the given example, if the value of a is greater than 0 statement x will be executed and will provide the output message “Positive”.

 Sub Main()
 Dim num As Integer
 Console.WriteLine("Enter a positive number:")
 num = Console.ReadLine()
 If num > 0 Then
 Console.WriteLine("Number is valid")
