   IEnumerable<T2> source,
   Func<T2,object> keySelector,
   Func<T,IEnumerable<T2>,TResult> resultSelector
)

Parameters

keySelector: A function to extract from an item of the second sequence the value to match against this collection's key value.
resultSelector: A function to create a result element from an element from this collection and a collection of matching elements from the second sequence.
