vb.NET If Then Replacement

Question

In a quick project, I have to use the If command to check if a radio button is checked or not, if it is checked I would make the Form's back color be replaced with the Radio button's forecolor. Example:

If rdoRed.Checked = True Then
Me.Backcolor = rdoRed.Forecolor

The teacher then challenged us to do this without the If/then commands, how would I come around this?

Lol I already submitted my work, I was just looking for the answer — user3186159, Feb 04 '14 at 02:45
I just didn't take on the challenge of not using if/then since it was extra, but now that I'm done I want to find an answer Edit: This is the code I submitted: If rdoRed.Checked = True Then Me.Backcolor = rdoRed.Forecolor Elseif If rdoGreen.Checked = True Then Me.Backcolor = rdoGreen.Forecolor Elseif etc.etc. — user3186159, Feb 04 '14 at 02:55

Maybe you can use Select Case here:

Select Case rdoRed.Checked
    Case True
       Me.Backcolor = rdoRed.Forecolor
    Case Else
       'Some other color 
End Select

And you can also use IIF

Me.Backcolor = IIf(rdoRed.Checked, rdoRed.Forecolor, Me.Backcolor)

Try a ternary operator.

Me.Backcolor = If(rdoRed.Checked, rdoRed.Forecolor, [some other color])

Like this example: Is there a conditional ternary operator in VB.NET?

OK... so this is a homework question.. but is it wrong? – Kenny Thompson Feb 04 '14 at 02:35
Technically it is different and you could argue your case. – Kenny Thompson Feb 04 '14 at 02:35
No, it would count as correct, but I was curious if I could carry out the same objective without using If/then – user3186159 Feb 04 '14 at 02:36
Well, thank you very much for your answer anyways, you did increase my knowledge on vb.NET and I'm sure to use this in the future :) – user3186159 Feb 04 '14 at 02:41
