此构造函数指定默认传播和继承。 即 和 InheritanceFlags.NonePropagationFlags.None。

此构造函数等效于通过NTAccount传递给identityNTAccount.NTAccount(String)构造函数并将新创建NTAccount的对象传递给构造函数来创建对象RegistryAccessRule(IdentityReference, RegistryRights, AccessControlType)。

参数

例外

注解

所有注册表项都是容器，因此唯一对注册表项有意义的继承标志是 InheritanceFlags.ContainerInherit 标志。 如果未指定此标志，则忽略传播标志，并且仅影响即时键。 如果该标志存在，则传播规则，如下表所示。 该表假定有一个子项 S，其中包含子子项 CS 和孙子项 GS。 也就是说，孙子项的路径为 S\CS\GS。

孙子项的模式控制孙子项包含的所有子项。

例如，如果 ContainerInherit 为 inheritanceFlags 指定标志，并为 InheritOnly 指定 propagationFlags传播标志，则此规则不适用于直接子项，但应用于其所有直接子项以及它们包含的所有子项。

示例

下面的代码示例演示具有继承和传播的访问规则。 该示例创建一个 对象，然后创建并添加两个 RegistrySecurity 具有 ContainerInherit 标志的规则。 第一个规则没有传播标志，而第二个规则具有 NoPropagateInherit 和 InheritOnly。

程序显示 对象中的 RegistrySecurity 规则，然后使用 RegistrySecurity 对象创建子项。 程序创建一个子子项和一个孙子项，然后显示每个子项的规则。 最后，程序删除测试密钥。
