hey all,
Label[] lbls = {Label1, Label2, Label3};

i know you can iterate thru the elements, cast to Label object, and then set
its visibility. But is there a way to set the elements all at once without
loop structures?
just wondering.

thanks,

Just to be clear: if you have an array declared as Label[], there is no
need to cast any element to a Label. Retrieving an element from the array
gives you something that's already a Label type.

Do you mean "set the visibility of each element"? That is, set
Label.Visible to "true" for each element? Or otherwise perform some
specific operation on each element?

If so, then no. Somewhere, something needs to loop on the elements.

However, there are of course ways to write code such that this looping is
done implicitly. For example, you could use the Array.ForEach() method,
which takes as a parameter a method to call for each element. You can
provide a method that sets the Visible property, and the ForEach() method
will call that other method repeatedly, once for each element in the array.
