Parameters
- source
- Type: System.Collections.GenericIEnumerableIGroupingTKey, TElement
The source sequence. - key1
- Type: TKey
The first key to partition on. - key2
- Type: TKey
The second key to partition on. - key3
- Type: TKey
The third key to partition on. - resultSelector
- Type: SystemFuncIEnumerableTElement, IEnumerableTElement, IEnumerableTElement, IEnumerableIGroupingTKey, TElement, TResult
Function that projects the result from elements of groups
matching key1, key2 and
key3 and those groups that do not (in the order
in which they appear in source), passed as
arguments.
Type Parameters

resultSelector.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableIGroupingTKey,
TElement. When you use instance method syntax to call this method, omit the first parameter. For more information, see
