Answer 1

OctetString community = new OctetString("public");            AgentParameters param = new AgentParameters(community);
            param.Version = SnmpVersion.Ver1;
            IpAddress agent = new IpAddress("192.168.0.50");            // Construct target
            UdpTarget target = new UdpTarget((IPAddress)agent, 161, 2000, 1);            // Pdu class used for all requests
            Pdu pdu = new Pdu(PduType.Get);
            pdu.VbList.Add("1.3.6.1.2.1.1.1.0"); //sysDescr
            pdu.VbList.Add("1.3.6.1.2.1.1.2.0"); //sysObjectID
            pdu.VbList.Add("1.3.6.1.2.1.1.3.0"); //sysUpTime
            pdu.VbList.Add("1.3.6.1.2.1.1.4.0"); //sysContact
            pdu.VbList.Add("1.3.6.1.2.1.1.5.0"); //sysName            // Make SNMP request
            
           SnmpV1Packet result = (SnmpV1Packet)target.Request(pdu, param);
           如果使用target.RequestAsync()//这个方法怎么写？            if (result != null)
            {
                // ErrorStatus other then 0 is an error returned by 
                // the Agent - see SnmpConstants for error definitions

                }
                else
                {

                    //  to the VbList
                    this.txtContent.Text += string.Format("sysDescr({0}) ({1}): {2} \r\n",

            }
            target.Dispose();
