VB.Net - Nested If Statements
Advertisements
It is always legal in VB.Net to nest If-Then-Else statements, which means you can use one If or ElseIf statement inside another If ElseIf statement(s).
Syntax
The syntax for a nested If statement is as follows −
If( boolean_expression 1)Then 'Executes when the boolean expression 1 is true If(boolean_expression 2)Then 'Executes when the boolean expression 2 is true End If End If
You can nest ElseIf...Else in the similar way as you have nested If statement.
Example
Live DemoModule decisions Sub Main() 'local variable definition Dim a As Integer = 100 Dim b As Integer = 200 ' check the boolean condition If (a = 100) Then ' if condition is true then check the following If (b = 200) Then ' if condition is true then print the following Console.WriteLine("Value of a is 100 and b is 200") End If End If Console.WriteLine("Exact value of a is : {0}", a) Console.WriteLine("Exact value of b is : {0}", b) Console.ReadLine() End Sub End Module
When the above code is compiled and executed, it produces the following result −
Value of a is 100 and b is 200 Exact value of a is : 100 Exact value of b is : 200
