How would I replicate this in C#?
Code: Private Sub Toppings_Click(ByVal sender As Object, ByVal e As System.EventArgs) _
Handles chkRelish.Click, chkKraut.Click, chkCheese.Click
Dim chkSelectedTopping As CheckBox = sender
If chkSelectedTopping.Checked Then
Select Case chkSelectedTopping.Tag
Case "Relish"
Case "Kraut"
Case "Cheese"
End Select
Else
End If

Code: private void Toppings_Click(object sender, EventArgs e) {
CheckBox chkSelectedTopping = sender as CheckBox;
if (chkSelectedTopping != null && chkSelectedTopping.Checked) {
switch (chkSelectedTopping.Tag as string) {
case "Relish":
break;
case "Kraut":
break;
case "Cheese":
break;
}
}
}
You can now either go and hook up this event handler via the property editor in the form designer (select chkRelish, go to the properties window, select CheckedChanged and pick Toppings_Click from the dropdown) or stick this in the form's constructor:
Code: this.chkRelish.CheckedChanged += new EventHandler(Toppings_Click);
this.chkKraut.CheckedChanged += new EventHandler(Toppings_Click);
this.chkCheese.CheckedChanged += new EventHandler(Toppings_Click);
Dare I ask what "Kraut" is? Over here it's a derogatory term for a German. :\ |

I knew translation to my mother language but from that to English is a little more hard... XD
*some minutes after*
Cabbage / collard green, but not totality sure.
Or something related to a grass or a herb.
I don't know how it ended to have other meanings than the common but it has a common. |

Would never have guessed. I got the example from a vb.net book. Following the flow of things yes it is a food (cabbage) over here in the states. Next time I'll change up the foods. I didn't like the ones they used either but I was too lazy to change what I saw. Sorry, meant no offense.
thanks for your help as always.
Kraut is actually sauerkraut though. Or that's what it's called.
Nasty food though: http://www.all-creatures.org/recipes/images/i-sauerkraut.jpg

Ah, I see. (I'm not offended, just curious)!
One thing I should probably have commented on was my use of the "as" keyword. In C#, you can convert types by casting them (CheckBox chkSelectedTopping = (CheckBox)sender;) - however, if sender cannot be converted to a CheckBox, that would throw an exception. When using the as keyword (CheckBox chkSelectedTopping = sender as CheckBox;) chkSelectedTopping will be null if sender couldn't be converted, and no exception is thrown. |
