Name	Return Value	Summary
GroupByMany<TSource, TKey, TElement>(IEnumerable<TSource>, Func<TSource, IEnumerable<TKey>>, Func<TSource, TElement>, IEqualityComparer<TKey>)	IEnumerable<IGrouping<TKey, TElement>>	Groups the elements of a sequence according to a specified key selector function that returns a sequence of keys. The keys are compared by using a comparer and each group's elements are projected by using a specified function. static
