IIf Function in VB.NET

IIF returns one of two objects, depending on the evaluation of an expression.

IIF is a function and it only specific to VB.NET, because in C# there is no IIF, so it is not the part Common Language Runtime. IIf is an alternative to the If...Then...Else statement in VB.NET

Both statements returns True.

Note :The expressions in the argument list can include function calls.

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim value As Integer = 190

        MsgBox(IIf(value > 100, "higher", "smaller"))

        ' The following If..Else..statements return the same result

        If value > 100 Then
        End If
    End Sub
