How to handle an exception if the connection is down or the server doesn't disconnect?

var ws = new WebSocket("ws://localhost/client_websocket")
            { 
                ws.OnOpen += (sender, e) => this.Connected();
            
                ws.OnMessage += (sender, e) => Console.WriteLine(e.Data);
    
    
                ws.OnError += (sender, e) =>//делаем что-то при ошибке
    
                ws.OnClose += (sender, e) => //делаем что-то при отключении
    
                ws.Connect();
                while (true)
                {
                }
            }

Answer 1

It was just necessary to turn off log
ws.Log.Output = (LogData data, string path) => { };
