LinkedListNode.List プロパティ

.NET Framework クラス ライブラリ リファレンス

LinkedListNode.List プロパティ

メモ : このプロパティは、.NET Framework version 2.0 で新しく追加されたものです。

LinkedListNode が属する LinkedList を取得します。

名前空間: System.Collections.Generic
アセンブリ: System (system.dll 内)
構文

Visual Basic (宣言)

Public ReadOnly Property
 List As LinkedList(Of T)

Visual Basic (使用法)

Dim instance As LinkedListNode(Of
 T)
Dim value As LinkedList(Of
 T)

value = instance.List

C#

public LinkedList<T> List { get; }

C++

public:
property LinkedList<T>^ List {
    LinkedList<T>^ get ();
}

J#

/** @property */
public LinkedList<T> get_List ()

JScript

public function get List
 () : LinkedList<T>

プロパティ値
LinkedListNode が属する LinkedList への参照。LinkedListNode がリンクされていない場合は、null 参照 (Visual Basic では Nothing)。

使用例

LinkedListNode を作成して LinkedList に追加し、LinkedList が変更された場合に、プロパティ値を追跡するコード例を次に示します。
