Enumerable.Average Method (IEnumerable<Int32>)

public static double Average(
	this IEnumerable<int> 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<Int32>) to calculate an average.

      List<int> grades = new List<int> { 78, 92, 100, 37, 81 };

      double average = grades.Average();

      outputBlock.Text += String.Format("The average grade is {0}.", average) + "\n";

      // This code produces the following output:
      //
      // The average grade is 77.6.
