Enumerable.GroupBy (this IEnumerable<TSource>, Func<TSource, TKey>) 

Groups the elements of a sequence according to a specified key selector function.  

 

Enumerable.GroupBy (this IEnumerable<TSource>, Func<TSource, TKey>, Func<TKey, IEnumerable<TSource>, TResult>) 

Groups the elements of a sequence according to a key selector function. The keys are compared by using a comparer and each group's elements are projected by using a specified function.  

 

Enumerable.GroupBy (this IEnumerable<TSource>, Func<TSource, TKey>, Func<TKey, IEnumerable<TSource>, TResult>, IEqualityComparer<TKey>) 

Groups the elements of a sequence according to a specified key selector function and creates a result value from each group and its key. The elements of each group are projected by using a specified function.  

 

Enumerable.GroupBy (this IEnumerable<TSource>, Func<TSource, TKey>, Func<TSource, TElement>) 

Groups the elements of a sequence according to a specified key selector function and projects the elements for each group by using a specified function.  

 

Enumerable.GroupBy (this IEnumerable<TSource>, Func<TSource, TKey>, Func<TSource, TElement>, Func<TKey, IEnumerable<TElement>, TResult>) 

Groups the elements of a sequence according to a specified key selector function and creates a result value from each group and its key. The keys are compared by using a specified comparer.
