示例

下面的代码示例演示如何在创建EventWaitHandleRights和使用EventWaitHandleAccessRule对象时使用值。The following code example demonstrates the use of EventWaitHandleRights values when creating and using EventWaitHandleAccessRule objects. 该示例创建一个EventWaitHandleSecurity对象, 添加允许和拒绝当前用户的各种权限的规则, 并显示生成的规则对。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. 然后, 该示例允许当前用户具有新权限, 并显示结果, 并显示新权限与现有AccessControlType.Allow规则合并。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.

备注

此示例不会将安全对象附加EventWaitHandle到对象; 请参见EventWaitHandleSecurityEventWaitHandle.GetAccessControl方法和。 EventWaitHandle.SetAccessControlThis example does not attach the security object to an EventWaitHandle object; see EventWaitHandleSecurity, EventWaitHandle.GetAccessControl method, and EventWaitHandle.SetAccessControl.

注解

在创建EventWaitHandleAccessRule对象时, 使用枚举指定访问控制权限。EventWaitHandleRightsUse the EventWaitHandleRights enumeration to specify access control rights when you create EventWaitHandleAccessRule objects. 若要将访问权限应用于已命名的系统事件EventWaitHandleAccessRule , 首先要EventWaitHandleSecurity将对象添加到EventWaitHandleSecurity对象, 然后使用EventWaitHandle.EventWaitHandle(Boolean, EventResetMode, String, Boolean, EventWaitHandleSecurity)构造函数或EventWaitHandle.SetAccessControl方法将对象附加到已命名的系统事件。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.

备注

Windows 98 或 Windows Millennium Edition 不支持同步对象的安全性。Security on synchronization objects is not supported for Windows 98 or Windows Millennium Edition.
