I was looking at this:
http://msdn.microsoft.com/en-us/library/9k7k7cf0.aspx

Which seems to do the same as this:

List<int> Values = GetPowers(2, 8);
foreach (int i in Values)
{
    Console.Write("{0} ", i);
}


public static List<int> GetPowers(int number, int exponent)
{
    List<int> RetVal = new List<int>();

    int counter = 0;
    int result = 1;
    while (counter++ < exponent)
    {
        result = result * number;
        RetVal.Add(result);
    }

    return RetVal;
}

The yield statement calls into the Power methid repeatedly. This seems rather confusing to me, as apposed to my code above that
gets and returns all the values at once, the processes them.

I'd like to know what others think.
