Examples

The following example inherits from the ResourcePermissionBase class. 4 kinds of constructors are implemented. The example also provides an implementation of a class called MailslotPermissionEntry. The PermissionAccessType property is then privately set to the type of MailslotPermissionEntry. The TagNames property is set privately to "Name" and "Machine".
