FromLevels Constructs a grouping from the specified collection of level indexes.
Group<TInput>(IEnumerable<TInput>) Returns a grouping by the unique elements in a sequence.
Group<TInput>(IList<TInput>) Returns a grouping by the unique elements in a list.
Group<TInput>(IEnumerable<TInput>, IEqualityComparer<TInput>) Returns a grouping by the unique elements in a sequence using the specified comparer to determine equality.
Group<TInput>(IList<TInput>, IEqualityComparer<TInput>) Returns a grouping by the unique elements in a list using the specified comparer to determine equality.
