Calling variables by string

[charlie]

Hi all!

Is there any way for calling variables as strings? I mean, if I have two Labels (label1 and label2, I want to call'em with something like:

for (int i=1; i<3; i++)
{
   whatever("label" + i).Text = "C# forum - Label " + i;
}

Thanks a lot! :)

You could use an array of labels and loop through them or alternatively loop through the Form's Controls collection and compare the control name to the string.

Hi Charlie, As PlausiblyDamp mentioned, it is trivial to loop through all the controls of a form and identify them by type or name. Here is some code:

[color=Blue]int[/color] labelCount = 0;
[color=Blue]for[/color] ([color=Blue]int[/color] i = 0; i < [color=Blue]this[/color].Controls.Count; i++)
[color=Blue]if[/color] ([color=Blue]this[/color].Controls[i].GetType().ToString().EndsWith("Label"))
	labelCount++;
label1.Text = labelCount.ToString();

I used Label1 just to give me a label to count. I hope this helps.

Thanks! That's what I wanted! :)
