Public Sub Connect ()

Esempio

Nell'esempio seguente viene inizializzato un nuovo ManagementScope con un percorso specifico e quindi si connette l'oggetto ambito a uno spazio dei nomi WMI. L'esempio si connette a uno spazio dei nomi in un computer remoto.

using System.Management;
public class RemoteConnect
{
    public static void Main()
    {
        /*// Build an options object for the remote connection
        //   if you plan to connect to the remote
        //   computer with a different user name
        //   and password than the one you are currently using

             ConnectionOptions options =
                 new ConnectionOptions();

             // and then set the options.Username and
             // options.Password properties to the correct values
             // and also set
             // options.Authority = "ntlmdomain:DOMAIN";
             // and replace DOMAIN with the remote computer's
             // domain.  You can also use Kerberos instead
