Using C# to recursively get a collection of controls from a controlcollection

Question

Currently I am trying to extract a collection of dynamically created controls (checkboxes and dropdownlists) from a recursive control collection (repeater). This is the cod

Answer 1

Change it to

var c = control as T;
if (c != null)
    resultCollection.Add(c);

This will be faster than your cod, since it doesn't call GetType().
Note that it will also add controls that inherit T.

You'll also need to constrain the type parameter by adding where T : Control.
