Ejemplos

En el ejemplo siguiente se inicializa un nuevo ManagementScope con una ruta de acceso específica y, a continuación, se conecta el objeto de ámbito a un espacio de nombres WMI. El ejemplo se conecta a un espacio de nombres en un equipo remoto.

using System;
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
             // of ntlmdomain.
        */

        // Make a connection to a remote computer.
        // Replace the "FullComputerName" section of the
        // string "\\\\FullComputerName\\root\\cimv2" with
        // the full computer name or IP address of the
        // remote computer.
