array manipulations - rodcha

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,
rodchar

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 arr=
ay  =

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 i=
s  =

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() metho=
d  =

will call that other method repeatedly, once for each element in the arr=
ay.
