Compiled information on a computer-related system
We need to introduce namespace:
1. In the 'Solution Explorer' window -> right-click the project -> 'Add' -> 'references' pop citation manager
2. In reference to a processor, the assembly -> frame -> select 'System.Management' -> Confirm

ok, today to share this, and if in doubt can leave a message, not to speak of the welcome that! ! !
