注釈

(EventWaitHandle、WaitOne、または WaitAny メソッドを呼び出して) WaitAllを待機するには、ユーザーにEventWaitHandleRights.Synchronizeアクセス権が必要です。 Set メソッドを呼び出してイベントを通知したり、Reset メソッドを呼び出してイベントを符号なし状態にリセットしたりするには、ユーザーにEventWaitHandleRights.Modifyアクセス権が必要です。 EventWaitHandle オブジェクトに通知し、SignalAndWait メソッドを呼び出して待機するには、ユーザーにSynchronizeとModifyアクセス権が必要です。

例

次のコード例は、このコンストラクターを使用して EventWaitHandleAccessRule オブジェクトを作成する方法を示しています。 この例では、 EventWaitHandleSecurity オブジェクトを作成し、現在のユーザーのさまざまな権限を許可および拒否する規則を追加し、結果の規則のペアを表示します。 次の使用例は、現在のユーザーに対して新しい権限を許可し、結果を表示し、新しい権限が既存の Allow ルールとマージされていることを示します。

このコンストラクターは、NTAccount コンストラクターにidentityを渡し、新しく作成したNTAccount.NTAccount(String) オブジェクトをNTAccount コンストラクターに渡すことで、EventWaitHandleAccessRule(IdentityReference, EventWaitHandleRights, AccessControlType) オブジェクトを作成することと同じです。
