注釈

LinkedList<T> は汎用リンク リストです。 列挙子をサポートし、.NET Framework の他のコレクション クラスと一致する ICollection インターフェイスを実装します。

LinkedList<T> は、LinkedListNode<T>型の個別のノードを提供するため、挿入と削除は O(1) 操作です。

ノードを削除して、同じリストまたは別のリストに再挿入することができます。その結果、ヒープに追加のオブジェクトが割り当てられません。 リストも内部カウントを保持するため、Count プロパティの取得は O(1) 操作です。

LinkedList<T> オブジェクト内の各ノードは、LinkedListNode<T>型です。 LinkedList<T> は 2 重にリンクされているため、各ノードは Next ノードを指し、Previous ノードに戻ります。

ノードとその値が同時に作成されると、参照型を含むリストのパフォーマンスが向上します。 LinkedList<T> は、参照型の有効な Value プロパティとして null を受け入れ、値の重複を許可します。

LinkedList<T> が空の場合、First プロパティと Last プロパティには nullが含まれます。

LinkedList<T> クラスは、チェーン、分割、サイクル、またはその他の機能をサポートしていません。一覧が不整合な状態のままになる可能性があります。 一覧は、1 つのスレッドで一貫性が保たれます。 LinkedList<T> でサポートされる唯一のマルチスレッド シナリオは、マルチスレッド読み取り操作です。

スレッド セーフ

この型はスレッド セーフではありません。 LinkedList<T> に複数のスレッドからアクセスする必要がある場合は、独自の同期メカニズムを実装する必要があります。

コレクションが変更されない限り、LinkedList<T> は複数のリーダーを同時にサポートできます。 それでも、コレクションを列挙することは本質的にスレッド セーフなプロシージャではありません。 列挙が書き込みアクセスと競合するまれなケースでは、列挙全体の間にコレクションをロックする必要があります。 読み取りと書き込みのためにコレクションに複数のスレッドからアクセスできるようにするには、独自の同期を実装する必要があります。
