RegistryPermission Class (System.Security.Permissions) (original) (raw)

Definition

Caution

Code Access Security is not supported or honored by the runtime.

Controls the ability to access registry variables. This class cannot be inherited.

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

RegistryPermission describes protected operations on registry variables. Registry variables should not be stored in memory locations where code without RegistryPermission can access them. If the registry object is passed to an untrusted caller it can be misused.

The allowed registry access types are defined by RegistryPermissionAccess. If more than one type of access is desired, they can be combined using the bitwise OR operation as shown in the code sample that follows.

Registry permission is defined in terms of canonical absolute paths; checks should always be made with canonical pathnames. Key access implies access to all values it contains and all variables under it.

Note

In versions of .NET Framework before .NET Framework 4, you could use the CodeAccessPermission.Deny method to prevent inadvertent access to system resources by trusted code. Deny is now obsolete, and access to resources is now determined solely by the granted permission set for an assembly. To limit access to files, you must run partially trusted code in a sandbox and assign it permissions only to resources that the code is allowed to access. For information about running an application in a sandbox, see How to: Run Partially Trusted Code in a Sandbox.
