Error {0} index {1}", 43 result.Pdu.ErrorStatus, 44 result.Pdu.ErrorIndex); 45 } 46 else 47 { 48 // Reply variables are returned in the same order as they were added 49 // to the VbList 50 Console.WriteLine("sysDescr({0}) ({1}): {2}", 51 result.Pdu.VbList[0].Oid.ToString(), 52 SnmpConstants.GetTypeName(result.Pdu.VbList[0].Value.Type), 53 result.Pdu.VbList[0].Value.ToString()); 54 } 55 } 56 else 57 { 58 Console.WriteLine("No response received from SNMP agent."); 59 } 60 target.Close(); 61 } 62 } 63 }  输出结果如下： 发送和接收的包的wireshark截图： get-request get-response   接下来，需要看如何获取网络拓扑。。。Visual C# 2015调用SnmpSharpNet库实现简单的SNMP元素查询标签：pad   desktop   .net   png   ace   community   tag   parameter   调用   原文地址：http://www.cnblogs.com/yanhc/p/7500669.html
