- source IEnumerableIGroupingTKey, TElement
- The source sequence.
- key TKey
- The key to partition.
- resultSelector FuncIEnumerableTElement, IEnumerableIGroupingTKey, TElement, TResult
-
Function that projects the result from sequences of elements
matching key and those groups that do not (in the
order in which they appear in source), passed as
arguments.
- TKey
- Type of keys in source groupings.
- TElement
- Type of elements in source
groupings.
- TResult
- Type of the result.
TResult
The return value from
resultSelector.
