備註

若要等待（ EventWaitHandle 呼叫 WaitOne， WaitAny 或 WaitAll 方法），使用者必須擁有 EventWaitHandleRights.Synchronize 存取權限。 若要呼叫該方法來通知事件 Set ，或透過呼叫 Reset 方法將其重置為未訊號狀態，使用者必須擁有 EventWaitHandleRights.Modify 存取權限。 要向物件發出訊號 EventWaitHandle 並透過呼叫 SignalAndWait 方法等待，使用者必須擁有 Synchronize 和 Modify 存取權限。

範例

以下程式碼範例示範使用此建構子來建立 EventWaitHandleAccessRule 物件。 範例中建立一個 EventWaitHandleSecurity 物件，新增允許或拒絕當前使用者各種權利的規則，並顯示所產生的規則對。 範例接著允許現有使用者新增權限，並顯示結果，顯示新權限已與現有 Allow 規則合併。

此建構子等同於建立一個 NTAccount 物件，透過傳遞 identity 給 NTAccount.NTAccount(String) 建構者，再將新建立 NTAccount 的物件傳給 EventWaitHandleAccessRule(IdentityReference, EventWaitHandleRights, AccessControlType) 建構子。
