RegisteredWaitHandle メソッド

名前 | 説明 | |
---|---|---|
![]() | CreateObjRef | リモート オブジェクトとの通信に使用するプロキシの生成に必要な情報をすべて格納しているオブジェクトを作成します。 ( MarshalByRefObject から継承されます。) |
![]() | Equals | オーバーロードされます。 2 つの Object インスタンスが等しいかどうかを判断します。 ( Object から継承されます。) |
![]() | GetHashCode | 特定の型のハッシュ関数として機能します。GetHashCode は、ハッシュ アルゴリズムや、ハッシュ テーブルのようなデータ構造での使用に適しています。 ( Object から継承されます。) |
![]() | GetLifetimeService | 対象のインスタンスの有効期間ポリシーを制御する、現在の有効期間サービス オブジェクトを取得します。 ( MarshalByRefObject から継承されます。) |
![]() | GetType | 現在のインスタンスの Type を取得します。 ( Object から継承されます。) |
![]() | InitializeLifetimeService | 対象のインスタンスの有効期間ポリシーを制御する、有効期間サービス オブジェクトを取得します。 ( MarshalByRefObject から継承されます。) |
![]() | ReferenceEquals | 指定した複数の Object インスタンスが同一かどうかを判断します。 ( Object から継承されます。) |
![]() | ToString | 現在の Object を表す String を返します。 ( Object から継承されます。) |
![]() | Unregister | RegisterWaitForSingleObject メソッドで実行した登録済みの待機操作をキャンセルします。 |

RegisteredWaitHandle メンバ
