Type: System.String

A list of registry variables (semicolon-separated) to which access is granted.


The access parameter is not a valid value of RegistryPermissionAccess.


The pathList parameter is not a valid string.

This constructor allows only one of the RegistryPermissionAccess values to be specified. This access applies to all listed registry variables. Use AddPathList to define more complicated permissions.

The control parameter specifies whether the access control list (ACL) for the registry keys specified by pathList can be changed, viewed, or cannot be accessed.

Important noteImportant

An access control list (ACL) describes individuals or groups who have, or do not have, rights to specific actions on the specified registry keys. The ability to change or view an ACL is an important permission and should be granted with caution.
