Enumerable.Average Method (IEnumerable<Nullable<Int64>>)

public static Nullable<double> Average(
	this IEnumerable<Nullable<long>> source
)

Usage Note

In Visual Basic query expression syntax, an Aggregate Into Average() clause translates to an invocation of Average.

The following code example demonstrates how to use Average(IEnumerable<Nullable<Int64>>) to calculate an average.

            long?[] longs = { null, 10007L, 37L, 399846234235L };

            double? average = longs.Average();

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

            // This code produces the following output:
            //
            // The average is 133282081426.333.
