【C#】设置有线网卡IP地址，子网掩码，网关，DNS

方法

cs 复制代码

    {
        /// <summary>
        /// 设置IP地址，子网掩码，网关，DNS
        /// </summary>

                    inPar = mo.GetMethodParameters("EnableStatic");
                    inPar["IPAddress"] = new string[] { ipAddress };
                    inPar["SubnetMask"] = new string[] { subMask };
                    outPar = mo.InvokeMethod("EnableStatic", inPar, null);

                    //设置网关地址 
                    inPar = mo.GetMethodParameters("SetGateways");
                    inPar["DefaultIPGateway"] = new string[] { geteWay };
                    outPar = mo.InvokeMethod("SetGateways", inPar, null);

                    //设置DNS 
                    inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
                    inPar["DNSServerSearchOrder"] = new string[] { dnsMain, dnsBackup };
                    outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
                }

                //foreach (var item in mo.Properties)
                //{
                //    str.Append($"{item.Name}:{item.Value}\r\n");
