Demander Win32_ComputerSystem class remote

Question

Quelqu'un a-t-il un exemple de code C# sur la façon dont les objets de la classe Win32_ComputerSystem WMI peuvent être récupérés à partir d'un système distant en utilisant nom d'hôte, nom d'utilisateur et mot de passe?

Answer 1

Connexion:

try 
     { 
      rcOptions = new ConnectionOptions(); 
      rcOptions.Authentication = AuthenticationLevel.Packet; 
      rcOptions.Impersonation = ImpersonationLevel.Impersonate; 
      rcOptions.EnablePrivileges = true; 
      rcOptions.Username = servername + @"\" + username; 
      rcOptions.Password = password; 

      mScope = new ManagementScope(String.Format(@"\\{0}\root\cimv2", servername), rcOptions); 
      mScope.Connect(); 
      if (mScope.IsConnected == true) { MessageBox.Show("Connection Succeeded", "Alert"); } else { MessageBox.Show("Connection Failed", "Alert"); } 
      if (mScope.IsConnected == true) { lblConnectionStateWarning.Text = "Connected"; } else { lblConnectionStateWarning.Text = "Disconnected"; } //I have a label that displays connectionstate, you can leave that out 

     } 
     catch (Exception ex) { MessageBox.Show(ex.Message); }
