Parse (configuration["Port"]);//Get Service Port            varClient =NewConsulclient (Configurationoverview);//Callback gets            varresult = client. Agent.serviceregister (Newagentserviceregistration () {ID="Servernamefirst"+ Guid.NewGuid (),//Service number guaranteed not to repeatName ="Serverfirst",//name of the serviceAddress = IP,//Service IP AddressPort = port,//Service PortCheck =NewAgentservicecheck//Health Check{Deregistercriticalserviceafter= Timespan.fromseconds (5),//how long after the service is started, anti-registrationInterval = Timespan.fromseconds (Ten),//Health check interval, or heartbeat interval (the health of the Timing check service)HTTP = $"Http://{ip}:{port}/api/health",//Health Check AddressTimeout = Timespan.fromseconds (5)//time of registration of the service                }            }); }

<summary>////        Get an instance of Consul///</summary>//        <param name= "obj" ></param>        private static void Configurationoverview (Consulclientconfiguration obj)        {            //consul the address of            obj. Address = new Uri ("http://127.0.0.1:8500");            Data center named            obj. Datacenter = "DC1";        }
