linq Average

This sample uses Average to get the average of all numbers in an array.

public static void Average()
        {
            // Average - Simple
            int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };

            double averageNum = numbers.Average();

            Console.WriteLine("The average number is {0}.", averageNum);

            // Average - Projection
            string[] words = { "cherry", "apple", "blueberry" };

            double averageLength = words.Average(w => w.Length);

            Console.WriteLine("The average word length is {0} characters.", averageLength);
        }
