RegistryPermission.GetPathList(RegistryPermissionAccess) 方法

定义

获取具有指定 RegistryPermissionAccess 的所有注册表变量的路径。Gets paths for all registry variables with the specified RegistryPermissionAccess.

public:
 System::String ^ GetPathList(System::Security::Permissions::RegistryPermissionAccess access);
public string GetPathList (System.Security.Permissions.RegistryPermissionAccess access);
member this.GetPathList : System.Security.Permissions.RegistryPermissionAccess -> string
Public Function GetPathList (access As RegistryPermissionAccess) As String

参数

access
RegistryPermissionAccess

RegistryPermissionAccess 值之一,表示注册表变量访问的单一类型。One of the RegistryPermissionAccess values that represents a single type of registry variable access.

返回

String

具有指定 RegistryPermissionAccess 的注册表变量的列表(以分号分隔)。A list of the registry variables (semicolon-separated) with the specified RegistryPermissionAccess.

例外

access 不是 RegistryPermissionAccess 的一个有效值。access is not a valid value of RegistryPermissionAccess.

- 或 --or- accessAllAccess,表示注册表变量访问的多个类型,或者是 NoAccess,它不表示注册表变量访问的任何类型。access is AllAccess, which represents more than one type of registry variable access, or NoAccess, which does not represent any type of registry variable access.

示例

下面的代码示例演示方法的用法 GetPathListThe following code example shows the use of the GetPathList method.

// AddPathList adds access for the specified registry variables to the existing state of the permission.
// SetPathList sets new access for the specified registry variable names to the existing state of the permission.
// GetPathList gets paths for all registry variables with the specified RegistryPermissionAccess.

注解

使用此方法可以获取当前权限的状态。Use this method to get the state of the current permission. 对于每种类型的访问,必须单独调用此方法。You must call this method separately for each type of access.

备注

access参数限制为的值 RegistryPermissionAccess ,这些值表示单一类型的注册表变量访问。The access parameter is limited to the values of RegistryPermissionAccess, which represent single types of registry variable access. 这些值为 ReadWriteCreateThose values are Read, Write, and Create. 可接受的值 access 不包括 NoAccessAllAccess ,它们不表示单一类型的注册表变量访问。The values acceptable to access do not include NoAccess and AllAccess, which do not represent single types of registry variable access.
