code:
        public void initializeLogServer()
        {
            EasyUAClient _client = new EasyUAClient();
            _client.ServerConditionChanged += ServerConditionChanged;
        }
 
 
 
        private static void ServerConditionChanged(object sender, EasyUAServerConditionChangedEventArgs e)
        {
            Debug.WriteLine(e);
            if(e.Connected == true)

Hello

In my Client Application, I need to know if the client is connected at the moment or not.

To achieve this, I wrote this code:
private static void EasyUAClientOnLogEntry(object sender, LogEntryEventArgs logEntryEventArgs)
        {
            Debug.WriteLine(logEntryEventArgs);
 
            switch (logEntryEventArgs.EntryType.ToString())
            {
                case "Information":
                    Log.Information(logEntryEventArgs.Message);
                    break;
                case "Warning":
                    Log.Warning(logEntryEventArgs.Message);
                    break;
                default:
                    Log.Debug(logEntryEventArgs.EntryType + ": " + logEntryEventArgs.Message);
                    break;
            }
 
            if(logEntryEventArgs.Message.Contains("{BadTcpInternalError}") == true)
            {
                Log.Error("OPCUA Client is not connected");
                ValuesController.StateIO = false;
            }
            else if (logEntryEventArgs.Message.Contains("has successfully connected") == true)
            {
                Log.Information("OPCUA Client is connected");
                ValuesController.StateIO = true;
            }
        }

Is there a better way to do this?

Thanks in advance!
