Exemplos
O exemplo seguinte inicializa um novo ManagementScope com um caminho específico e depois liga o objeto de âmbito a um namespace WMI. O exemplo liga-se a um namespace num computador 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.
ManagementScope scope =
new ManagementScope(
"\\\\FullComputerName\\root\\cimv2");
scope.Connect();
// Use this code if you are connecting with a
// different user name and password:
//
// ManagementScope scope =
// new ManagementScope(
// "\\\\FullComputerName\\root\\cimv2", options);
// scope.Connect();
//Query system for Operating System information
ObjectQuery query = new ObjectQuery(
"SELECT * FROM Win32_OperatingSystem");

new ManagementObjectSearcher(scope,query);
ManagementObjectCollection queryCollection = searcher.Get();
foreach ( ManagementObject m in queryCollection)
