Parameters

source
ParallelQuery<TSource> ParallelQuery<TSource> ParallelQuery<TSource> ParallelQuery<TSource>

A sequence of values that are used to calculate an average.

selector
Func<TSource,Decimal>

A transform function to apply to each element.

Returns

The average of the sequence of values.

Exceptions

The query was canceled with the token passed in through WithCancellation.

source or selector is a null reference (Nothing in Visual Basic).

One or more exceptions occurred during the evaluation of the query.

(Thrown as inner exception in an AggregateException). The selector function returns a value greater than MaxValue for the element type.

Computes in parallel the average of a sequence of values that are obtained by invoking a transform function on each element of the input sequence.
