IF....THEN....ELSE
An If statement can be followed by an optional Else statement, which executes when the Boolean expression is false.
Syntax:
If (boolean_expression) Then
'statement(s) will execute if the Boolean expression is true
Else
'statement(s) will execute if the Boolean expression is false
End If
Where, condition is a Boolean or relational condition and Statement(s) is a simple or compound statement.
Example:
Dim a As Integer = 100
If (a < 20) Then
Console.WriteLine("a is less than 20")
Else
Console.WriteLine("a is not less than 20")
End If
If the condition evaluates to true, then the block of code inside the If statement will be executed. If condition evaluates to false, then the ELSE part will be executed.
