Check which server is the main

[CBRBO]

Hi, I would like to find out which node is the main server. I wrote this code but the state (by monitor.GetNodeState) is always null:

  static void Main(string[] args)
  {
      var credentials = new NetworkCredential("myusername", "mypw");
      ServerNode mainNode;

      ServerSystemCollection systems = new ServerSystemCollection();
      using (XmlReader reader = XmlReader.Create(@"\\geoscadaweb\c$\ProgramData\Schneider Electric\ClearSCADA\Systems.xml"))
      {
          systems = new ServerSystemCollection(reader);
      }
      ServerSystem system = systems["GEOSCADA"];
      ServerSystemMonitor monitor = new ServerSystemMonitor(system);
      monitor.Start(false);

      monitor.SetProvisionalLogOnCredentials(credentials.UserName, credentials.SecurePassword);
      foreach (var node in system.Nodes)
      {
          var state = monitor.GetNodeState(node);
          if (state != null && state.State == ServerState.Main)
          {
              mainNode = node;
              break;
          }
      }          

      monitor.Stop();
  }

I suggest you look this up in the Object Browser for the .Net API:

ClearScada.Client.ServerStateDetails GetServerState()
Member of ClearScada.Client.Advanced.IServer

Summary:
Gets the current state of the server.

Returns:
The current server state.

Thank you Sbeadle! It works! It's fantastic!

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ClearScada.Client;
using ClearScada.Client.Simple;
using System.Security;
using System.Net;
using System.Xml;


..........


var credentials = new NetworkCredential("myUser", "myPWD");
ServerNode mainNode;

ServerSystemCollection systems = new ServerSystemCollection();
using (XmlReader reader = XmlReader.Create(@"\\geoscadaweb\c$\ProgramData\Schneider Electric\ClearSCADA\Systems.xml"))
{
    systems = new ServerSystemCollection(reader);
}
ServerSystem system = systems["GEOSCADA"];
Connection conn = new Connection("TestApp");

foreach (var node in system.Nodes)
{
    if (node != null && !node.IsWebserver)
    {
        
        ServerNode serverNode = new ClearScada.Client.ServerNode(node.HostName, node.Port);
 
        conn.Connect(serverNode);

        var state = conn.Server.GetServerState();
        if (state != null && state.State == ServerState.Main)
        {
            mainNode = node;

            break;
        }
        conn.Disconnect();
    }
}
//Connected with main Server

And thank you for providing example code for the next person to use!
