修改IP地址
方法一：
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;”。
2、添加 “using System.Management;”。
1 static void SetNetworkAdapter() 2 { 3 ManagementBaseObject inPar = null; 4 ManagementBaseObject outPar = null; 5 ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); 6 ManagementObjectCollection moc = mc.GetInstances(); 7 foreach (ManagementObject mo in moc) 8 { 9 if (!(bool)mo["IPEnabled"]) 10 continue; 11 12 //设置ip地址和子网掩码 13 inPar = mo.GetMethodParameters("EnableStatic"); 14 inPar["IPAddress"] = new string[] { "192.168.16.248", "192.168.16.249" };// 1.备用 2.IP 15 inPar["SubnetMask"] = new string[] { "255.255.255.0", "255.255.255.0" }; 16 outPar = mo.InvokeMethod("EnableStatic", inPar, null); 17 18 //设置网关地址 19 inPar = mo.GetMethodParameters("SetGateways"); 20 inPar["DefaultIPGateway"] = new string[] { "192.168.16.2", "192.168.16.254" }; // 1.网关;2.备用网关 21 outPar = mo.InvokeMethod("SetGateways", inPar, null); 22 23 //设置DNS 24 inPar = mo.GetMethodParameters("SetDNSServerSearchOrder"); 25 inPar["DNSServerSearchOrder"] = new string[] { "211.97.168.129", "202.102.152.3" }; // 1.DNS 2.备用DNS 26 outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null); 27 break; 28 } 29 }
