Summary
Applies an accumulator function over an sequence, returning the result of the aggregation as a single element in the result sequence.
For aggregation behavior with incremental intermediate results.
Syntax
public static TSource Reduce<TSource>(this IEnumerable<TSource> source, Func<TSource, TSource, TSource> accumulator)
The return type of this operator differs from the corresponding operator on IEnumerable in order to retain asynchronous behavior.
