MoreEnumerablePartitionTKey, TElement, TResult Method (IEnumerableIGroupingTKey, TElement, TKey, TKey, TKey, FuncIEnumerableTElement, IEnumerableTElement, IEnumerableTElement, IEnumerableIGroupingTKey, TElement, TResult)

MoreEnumerablePartitionTKey, TElement, TResult Method (IEnumerableIGroupingTKey, TElement, TKey, TKey, TKey, FuncIEnumerableTElement, IEnumerableTElement, IEnumerableTElement, IEnumerableIGroupingTKey, TElement, TResult)

Partitions a grouping and projects a result from elements groups matching a set of three keys and those groups that do not.

Namespace: MoreLinq
Assembly:

MoreLinq (in MoreLinq.dll) Version: 3.0.0

Syntax

public static TResult Partition<TKey, TElement, TResult>(
	this IEnumerable<IGrouping<TKey, TElement>> source,
	TKey key1,
	TKey key2,
	TKey key3,
	Func<IEnumerable<TElement>, IEnumerable<TElement>, IEnumerable<TElement>, IEnumerable<IGrouping<TKey, TElement>>, TResult> resultSelector
)

<ExtensionAttribute>
Public Shared Function Partition(Of TKey, TElement, TResult) ( 
	source As IEnumerable(Of IGrouping(Of TKey, TElement)),
	key1 As TKey,
	key2 As TKey,
	key3 As TKey,
	resultSelector As Func(Of IEnumerable(Of TElement), IEnumerable(Of TElement), IEnumerable(Of TElement), IEnumerable(Of IGrouping(Of TKey, TElement)), TResult)
) As TResult

public:
[ExtensionAttribute]
generic<typename TKey, typename TElement, typename TResult>
static TResult Partition(
	IEnumerable<IGrouping<TKey, TElement>^>^ source, 
	TKey key1, 
	TKey key2, 
	TKey key3, 
	Func<IEnumerable<TElement>^, IEnumerable<TElement>^, IEnumerable<TElement>^, IEnumerable<IGrouping<TKey, TElement>^>^, TResult>^ resultSelector
)

[<ExtensionAttribute>]
static member Partition : 
        source : IEnumerable<IGrouping<'TKey, 'TElement>> * 
        key1 : 'TKey * 
        key2 : 'TKey * 
        key3 : 'TKey * 
        resultSelector : Func<IEnumerable<'TElement>, IEnumerable<'TElement>, IEnumerable<'TElement>, IEnumerable<IGrouping<'TKey, 'TElement>>, 'TResult> -> 'TResult

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

TKey: Type of keys in source groupings.
TElement: Type of elements in source groupings.
TResult: Type of the result.

Return Value

Type:

TResult

The return value from

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
