C# 修改IP、网关、DNS

1、在 “解决方案资源管理器” 右击 “引用” 添加 “System.Management” 的引用。 2、添加 “using System.Management;”。         static void SetNetworkAdapter()         {             ManagementBaseObject inPar = null;             ManagementBaseObject outPar = null;             ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");             ManagementObjectCollection moc = mc.GetInstances();             foreach (ManagementObject mo in moc)             {                 if (!(bool)mo["IPEnabled"])                     continue;                 //设置ip地址和子网掩码                 inPar = mo.GetMethodParameters("EnableStatic");                 inPar["IPAddress"] = new string[] { "192.168.16.248", "192.168.16.249" };// 1.备用 2.IP                 inPar["SubnetMask"] = new string[] { "255.255.255.0", "255.255.255.0" };                 outPar = mo.InvokeMethod("EnableStatic", inPar, null);                 //设置网关地址                 inPar = mo.GetMethodParameters("SetGateways");                 inPar["DefaultIPGateway"] = new string[] { "192.168.16.2", "192.168.16.254" }; // 1.网关;2.备用网关                 outPar = mo.InvokeMethod("SetGateways", inPar, null);                 //设置DNS                 inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");                 inPar["DNSServerSearchOrder"] = new string[] { "211.97.168.129", "202.102.152.3" }; // 1.DNS 2.备用DNS                 outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);                 break;             }         }
