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。
コンストラクター
LinkedList<T>() |
空の LinkedList<T> クラスの新しいインスタンスを初期化します。 |
LinkedList<T>(IEnumerable<T>) |
指定した IEnumerable からコピーされた要素を含み、コピーされた要素の数に対応できる十分な容量を持つ、LinkedList<T> クラスの新しいインスタンスを初期化します。 |
LinkedList<T>(SerializationInfo, StreamingContext) |
古い.
指定した SerializationInfo と StreamingContextでシリアル化できる LinkedList<T> クラスの新しいインスタンスを初期化します。 |
プロパティ
Count |
LinkedList<T>に実際に含まれるノードの数を取得します。 |
First |
LinkedList<T>の最初のノードを取得します。 |
Last |
LinkedList<T>の最後のノードを取得します。 |
メソッド
明示的なインターフェイスの実装
ICollection.CopyTo(Array, Int32) |
特定の Array インデックスから始まる ICollection の要素を Arrayにコピーします。 |
ICollection.IsSynchronized |
ICollection へのアクセスが同期されているかどうかを示す値を取得します (スレッド セーフ)。 |
ICollection.SyncRoot |
ICollectionへのアクセスを同期するために使用できるオブジェクトを取得します。 |
ICollection<T>.Add(T) |
ICollection<T>の末尾に項目を追加します。 |
ICollection<T>.IsReadOnly |
ICollection<T> が読み取り専用かどうかを示す値を取得します。 |
IEnumerable.GetEnumerator() |
リンク リストをコレクションとして反復処理する列挙子を返します。 |
IEnumerable<T>.GetEnumerator() |
コレクションを反復処理する列挙子を返します。 |
拡張メソッド
適用対象
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。
