1、在 “解決方案資源管理器” 右擊 “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;

                //設置ip地址和子網掩碼
                inPar = mo.GetMethodParameters("EnableStatic");
                inPar["IPAddress"] = new string[] { "192.168.16.248", "192.168.16.249" };// 1.備用 2.IP
                inPar["SubnetMask"] = new string[] { "255.255.255.0", "255.255.255.0" };
                outPar = mo.InvokeMethod("EnableStatic", inPar, null);

                //設置網關地址
                inPar = mo.GetMethodParameters("SetGateways");
                inPar["DefaultIPGateway"] = new string[] { "192.168.16.2", "192.168.16.254" }; // 1.網關;2.備用網關
                outPar = mo.InvokeMethod("SetGateways", inPar, null);

                //設置DNS
                inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
                inPar["DNSServerSearchOrder"] = new string[] { "211.97.168.129", "202.102.152.3" }; // 1.DNS 2.備用DNS
                outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
                break;
            }
        }
