a better way to make, and populate, a List ?

[C# Programming]

Current working code in a public static class: a List used internally:// required directives [1]:using System;using System.Windows.Forms;using System.Collections.Generic;////private static List OkToModify = new List { typeof(CheckBox), typeof(TextBox), typeof(Button), typeof(Panel), typeof(Label)};By "working:" I mean that I can use the List to test if a given Control passed into the public static class is okay for the uses I make of it. Through, simply:if (OkToModify.Contains(cntrl.GetType())) { processControl(cntrl) };I keep thinking that somewhere in my reading (Skeet ? StackOverFlow ?), or here on CP, I have seen a "niftier" way to do this.

Appreciate any alternatives.

thanks, Bill
