Why doesn't the Controls collection provide all of the IEnumerable methods?

Question

I\'m not for sure how the ControlCollection of ASP.Net works, so maybe someone can shed some light on this for me.

I recently discovered the magic that is extension

Answer 1

This is just because the ControlCollection class came around before generics; so it implements IEnumerable but not IEnumerable.

Fortunately, there does exist a LINQ extension method on the IEnumerable interface that allows you to generate an IEnumerable through casting: Cast. Which means you can always just do this:

var c = Controls.Cast().Where(x => x.ID == "Some ID").SingleOrDefault();
