The RegistryPermission class, which is in the System.Security.Permissions namespace, controls access to registry variables. Registry variables should not be stored in memory locations where code without RegistryPermission can access them. Similarly, when granting permissions, grant only those privileges necessary to get the job done.
Registry permission access values are defined by the RegistryPermissionAccess enumeration. The following table details its members.
| Value | Description |
|---|---|
| AllAccess | Create, read, and write access to registry variables. |
| Create | Create access to registry variables. |
| NoAccess | No access to registry variables. |
| Read | Read access to registry variables. |
| Write | Write access to registry variables. |
