以c#编程方式设置网络配置

我想保存我的网络适配器配置，然后在另一台计算机上恢复它。我使用WMI来获取我的网络配置，并将其保存到。txt文件中:

   using (TextWriter tw = new StreamWriter(@"D:''NetworkConfiguration.txt"))
        {
            if (tw != null)
            {
                ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
                ManagementObjectCollection objMOC = objMC.GetInstances();
                foreach (ManagementObject objMO in objMOC)
                {
                    if (!(bool)objMO["ipEnabled"])
                        continue;
                    string[] ipaddresses = (string[])objMO["IPAddress"];
                    string[] subnets = (string[])objMO["IPSubnet"];
                    string[] gateways = (string[])objMO["DefaultIPGateway"];

                    tw.WriteLine("IpAdresses");
                    foreach (string sIP in ipaddresses)
                        tw.WriteLine(sIP);
                    tw.WriteLine("IpSubnets");
                    foreach (string sNet in subnets)
                        tw.WriteLine(sNet);
                    tw.WriteLine("Gateways");
                    foreach (string sGate in gateways)
                        tw.WriteLine(sGate);

                    // close the stream
                    tw.Close();
                }
            }
        }

然后，当我想在另一台计算机上设置tcp/ip设置时，我读取文件的信息:

 using (TextReader tr = new StreamReader(@"D:''NetworkConfiguration.txt"))
            {
                List<string> ipAddrr = new List<string>();
                List<string> ipSubnet = new List<string>();
                List<string> Gateway = new List<string>();
                string line = tr.ReadLine();
                while (line != null)
                {
                    if (line.Equals("IpAdresses"))
                    {
                        ipAddrr.Add(tr.ReadLine());
                        ipAddrr.Add(tr.ReadLine());
                    }
                    if (line.Equals("IpSubnets"))
                    {
                        ipSubnet.Add(tr.ReadLine());
                        ipSubnet.Add(tr.ReadLine());
                    }
                    if (line.Equals("Gateways"))
                    {
                        Gateway.Add(tr.ReadLine());
                    }
                    line = tr.ReadLine();
                }
                setIP(ipAddrr.ToArray(), ipSubnet.ToArray(), Gateway.ToArray());
            }

并设置新设置:

public void setIP(string[] IPAddress, string[] SubnetMask, string[] Gateway)
    {
        ManagementClass objMC = new ManagementClass(
            "Win32_NetworkAdapterConfiguration");
        ManagementObjectCollection objMOC = objMC.GetInstances();

        foreach (ManagementObject objMO in objMOC)
        {
            if (!(bool)objMO["IPEnabled"])
                continue;

            try
            {
                ManagementBaseObject objNewIP = null;
                ManagementBaseObject objSetIP = null;
                ManagementBaseObject objNewGate = null;

                objNewIP = objMO.GetMethodParameters("EnableStatic");
                objNewGate = objMO.GetMethodParameters("SetGateways");

                //Set DefaultGateway
                objNewGate["DefaultIPGateway"] = Gateway ;
                objNewGate["GatewayCostMetric"] = new int[] { 1 };

                //Set IPAddress and Subnet Mask
                objNewIP["IPAddress"] = IPAddress;
                objNewIP["SubnetMask"] = SubnetMask;
                objSetIP = objMO.InvokeMethod("EnableStatic", objNewIP, null);
                objSetIP = objMO.InvokeMethod("SetGateways", objNewGate, null);

                MessageBox.Show(
                   "Updated IPAddress, SubnetMask and Default Gateway!");

            }
            catch (Exception ex)
            {
                MessageBox.Show("Unable to Set IP : " + ex.Message);
            }
        }
    }

，但问题是，当我检查我的tcp/ip配置，它永远不会改变.....我不知道怎么让它工作....
