The average of the sequence of values, or null if the source sequence is empty or contains only values that are null.
Usage NoteIn Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<Nullable<Int32>>. When you use instance method syntax to call this method, omit the first parameter.
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.
This code example uses an overload of this overloaded method that is different from the specific overload that this topic describes. To extend the example to this topic, substitute the elements of the source sequence with elements of the appropriate numerical type.
