Enumerable::Average<TSource> Method (IEnumerable<TSource>^, Func<TSource, Decimal>^)
Computes the average of a sequence of Decimal values that are obtained by invoking a transform function on each element of the input sequence.
Assembly: System.Core (in System.Core.dll)
public: generic<typename TSource> [ExtensionAttribute] static Decimal Average( IEnumerable<TSource>^ source, Func<TSource, Decimal>^ selector )
A sequence of values that are used to calculate an average.
Return ValueType: System::Decimal
The average of the sequence of values.
The type of the elements of source.
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<TSource>(IEnumerable<TSource>^, Func<TSource, 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, change the body of the selector function.
