次のコード例は、オブジェクトをEventWaitHandleRights作成および使用EventWaitHandleAccessRuleするときの値の使用方法を示しています。The following code example demonstrates the use of EventWaitHandleRights values when creating and using EventWaitHandleAccessRule objects. この例ではEventWaitHandleSecurity 、オブジェクトを作成し、現在のユーザーに対してさまざまな権限を許可および拒否するルールを追加し、結果として得られるルールのペアを表示します。The example creates an EventWaitHandleSecurity object, adds rules that allow and deny various rights for the current user, and displays the resulting pair of rules. 次に、現在のユーザーに対して新しい権限を許可し、その結果を表示して、新しい権限がAccessControlType.Allow既存のルールとマージされていることを示します。The example then allows new rights for the current user and displays the result, showing that the new rights are merged with the existing AccessControlType.Allow rule.

注意

この例ではEventWaitHandle 、オブジェクトにセキュリティオブジェクトをアタッチしません。「」、 EventWaitHandle.GetAccessControl 「メソッド」、およびEventWaitHandle.SetAccessControl「」を参照してくださいEventWaitHandleSecurityThis example does not attach the security object to an EventWaitHandle object; see EventWaitHandleSecurity, EventWaitHandle.GetAccessControl method, and EventWaitHandle.SetAccessControl.

注釈

列挙体EventWaitHandleRightsを使用して、オブジェクトを作成EventWaitHandleAccessRuleするときのアクセス制御権限を指定します。Use the EventWaitHandleRights enumeration to specify access control rights when you create EventWaitHandleAccessRule objects. 名前付きシステムイベントにアクセス権を適用するにはEventWaitHandleAccessRule 、まずオブジェクトEventWaitHandleSecurityEventWaitHandleSecurityオブジェクトに追加した後、 EventWaitHandle.EventWaitHandle(Boolean, EventResetMode, String, Boolean, EventWaitHandleSecurity)コンストラクターまたはEventWaitHandle.SetAccessControlメソッドを使用して、オブジェクトを名前付きシステムイベントにアタッチします。To apply access rights to a named system event, first add EventWaitHandleAccessRule objects to an EventWaitHandleSecurity object, then attach the EventWaitHandleSecurity object to the named system event using the EventWaitHandle.EventWaitHandle(Boolean, EventResetMode, String, Boolean, EventWaitHandleSecurity) constructor or the EventWaitHandle.SetAccessControl method.

注意

同期オブジェクトのセキュリティは、Windows 98 または Windows Millennium Edition ではサポートされていません。Security on synchronization objects is not supported for Windows 98 or Windows Millennium Edition.
