asp.net，java 之修改IP等信息，读取IP配置信息后台代码

当初写这个的时候在网上查了多好资料，终于稀里糊涂的写出来了，放在这里，以后忘的时候看看

注：我这个是一个多网卡的代码，和单网卡一样的，就是多一层判断

       //自动获取IP   nicname为网卡信息，也就是网卡ID，这样才能确定要为哪个网卡配置
        public static void GetIp(string nicname)
        {
            ManagementClass wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = wmi.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                if ((bool)mo["IPEnabled"])
                {
                    if (mo["Caption"].Equals(nicname))
                    {
                        //重置DNS为空
                        mo.InvokeMethod("SetDNSServerSearchOrder", null);
                        //开启DHCP
                        mo.InvokeMethod("EnableDHCP", null);
                        break;
                    }
                }
            }
        }

 

 

//设置IP地址，掩码，网关和DNS，这些参数应该不难看懂吧，注意传过的都是数组的形式

        public static void SetIPAddress(string nicname,string[] ip, string[] submask, string[] getway, string[] dns)
        {

            ManagementClass wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = wmi.GetInstances();
            ManagementBaseObject inPar = null;
            ManagementBaseObject outPar = null;
            foreach (ManagementObject mo in moc)
            {
                //如果没有启用IP设置的网络设备则继续，主要是多网卡不可能每个网卡本地连接都连接着，这样就算是本地连接被断开也可以配置的
                if (!(bool)mo["IPEnabled"])
                    continue;
                    if (mo["Caption"].Equals(nicname))
                    {
                         //设置IP地址和掩码

                        if (ip != null && submask != null)
                        {

                            inPar = mo.GetMethodParameters("EnableStatic");
                            inPar["IPAddress"] = ip;
                            inPar["SubnetMask"] = submask;
                            outPar = mo.InvokeMethod("EnableStatic", inPar, null);
                        }
                        //设置网关地址
                        if (getway != null)
                        {
                            inPar = mo.GetMethodParameters("SetGateways");
                            inPar["DefaultIPGateway"] = getway;
                            outPar = mo.InvokeMethod("SetGateways", inPar, null);
                        }

                        //设置DNS地址
                        if (dns != null)
                        {
                            inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
                            inPar["DNSServerSearchOrder"] = dns;
                            outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
                        }
                    }
              
            }

        }

         //获取网络适配器信息，以LIST形式返回，去遍历就可以出来了
        public static ArrayList GetNICNames()
        {
            ArrayList nicNames = new ArrayList();
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();
           
            foreach(ManagementObject mo in moc)
            {
                if (!(bool)mo["IPEnabled"])
                    continue;
                    nicNames.Add(mo["Caption"]);
               
            }
            return nicNames;
        }

 

 

 //获取网卡IP信息等，注意，这里使用了out string这种类型，不懂得去查，因为我也查出来的，嘿嘿
        public static void getMessage(string nicname, out string[] ipAdresses, out string[] subnets, out string[] gateways, out string[] dnses)
        {
            ipAdresses = null;
            subnets = null;
            gateways = null;
            dnses = null;
         
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                if (!(bool)mo["IPEnabled"])
                    continue;
                if (mo["Caption"].Equals(nicname))
                {
                    ipAdresses = (string[])mo["IPAddress"];
                    subnets = (string[])mo["IPSubnet"];
                    gateways = (string[])mo["DefaultIPGateway"];
                    dnses = (string[])mo["DNSServerSearchOrder"];

                    break;
                }
            }      
        }

 

后台代理基本上就这些了，应该没差下什么吧。。。。。。
