Array.ConvertAll and List.ConvertAll

Just noticed this handy method:

using System;
using System.Collections.Generic;

class Test
{
    static void Main()
    {
        int[] numbers = new int[] { 65, 66, 67 };
        char[] chars = Array.ConvertAll(numbers, delegate(int number)
            { return (char)number; });

        //Print "ABC"
        Array.ForEach(chars, delegate(char ch) { Console.Write(ch); });

        Console.WriteLine();
        List<int> numberList = new List<int>(numbers);
        List<char> charList = numberList.ConvertAll(delegate(int number) 
            { return (char)number; });

        //Print "ABC"
        charList.ForEach(delegate(char ch) { Console.Write(ch); });

        Console.Read();
    }
}
