初始化 EventWaitHandleAccessRule 類別的新執行個體，指定套用此規則的使用者或群組、存取權限，以及允許還是拒絕指定的存取權限。

public:
 EventWaitHandleAccessRule(System::Security::Principal::IdentityReference ^ identity, System::Security::AccessControl::EventWaitHandleRights eventRights, System::Security::AccessControl::AccessControlType type);

public EventWaitHandleAccessRule (System.Security.Principal.IdentityReference identity, System.Security.AccessControl.EventWaitHandleRights eventRights, System.Security.AccessControl.AccessControlType type);

new System.Security.AccessControl.EventWaitHandleAccessRule : System.Security.Principal.IdentityReference * System.Security.AccessControl.EventWaitHandleRights * System.Security.AccessControl.AccessControlType -> System.Security.AccessControl.EventWaitHandleAccessRule

Public Sub New (identity As IdentityReference, eventRights As EventWaitHandleRights, type As AccessControlType)

參數

identity: IdentityReference

適用這項規則的使用者或群組。必須是型別 SecurityIdentifier，或是像是可以轉換成型別 NTAccount 的 SecurityIdentifier 的型別。

eventRights: EventWaitHandleRights

EventWaitHandleRights 值的位元組合，指定允許或拒絕的權限。

type: AccessControlType

其中一個 AccessControlType 值，指定允許還是拒絕權限。

例外狀況

ArgumentOutOfRangeException

eventRights 指定了無效的值。

-或-

type 指定了無效的值。

ArgumentNullException

identity 為 null。

-或-

eventRights 為零。

ArgumentException

identity 既不是 SecurityIdentifier 型別，也不是可以轉換成 NTAccount 型別的型別 (例如 SecurityIdentifier)。

備註

EventWaitHandle 若要藉由呼叫 WaitOne或 WaitAny WaitAll 方法) 等候 (，用戶必須具有存取權EventWaitHandleRights.Synchronize。若要藉由呼叫 Set 方法來發出事件訊號，或藉由呼叫 Reset 方法將事件重設為未簽署的狀態，用戶必須具有 EventWaitHandleRights.Modify 存取權。若要發出物件的訊 EventWaitHandle 號，然後藉由呼叫 SignalAndWait 方法來等候物件，用戶必須具有 Synchronize 和 Modify 存取權。

範例

下列程式代碼範例示範如何使用這個建構函式來建立 EventWaitHandleAccessRule 物件。此範例會 EventWaitHandleSecurity 建立物件、新增規則，以允許和拒絕目前使用者的各種許可權，並顯示產生的規則組。然後，此範例會允許目前使用者的新許可權，並顯示結果，顯示新許可權會與現有 Allow 規則合併。

注意

這個範例不會將安全性物件附加至 EventWaitHandle 物件。您可以在和 EventWaitHandle.SetAccessControl中找到EventWaitHandle.GetAccessControl附加安全性物件的範例。

備註

這個建構函式相當於建立 NTAccount 物件，方法是傳遞 identity 至 NTAccount.NTAccount(String) 建構函式，並將新建立 NTAccount 的對象傳遞至 EventWaitHandleAccessRule(IdentityReference, EventWaitHandleRights, AccessControlType) 建構函式。
