 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; 
 
                //设置ip地址和子网掩码 
                inPar = mo.GetMethodParameters( "EnableStatic" ); 
                inPar["IPAddress"] = new string[] { "10.22.21.111","192.168.10.9" }; 
                inPar["SubnetMask"] = new string[] { "255.255.255.0","255.255.255.0" }; 
                outPar = mo.InvokeMethod( "EnableStatic", inPar, null ); 
 
                //设置网关地址 
                inPar = mo.GetMethodParameters("SetGateways"); 
                inPar["DefaultIPGateway"] = new string[] { "10.22.21.1","192.168.10.1"}; 
                outPar = mo.InvokeMethod( "SetGateways", inPar, null ); 
 
                //设置DNS 
                inPar = mo.GetMethodParameters("SetDNSServerSearchOrder"); 
                inPar["DNSServerSearchOrder"] = new string[] {"179.32.42.4","179.32.42.5"}; 
                outPar = mo.InvokeMethod( "SetDNSServerSearchOrder" ,inPar,null); 
                    break; 
            } 
        }

楼主说不用WMI哦上面的不行吧！期待中最好有牛人自己写一个组件出来哦！好好学

Answer 3

不用使用WMI，下面这样也可以。
//获取本地连接信息
NetworkInterface[] NetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
            foreach (NetworkInterface NetworkIntf in NetworkInterfaces)
            {
                if(NetworkIntf.NetworkInterfaceType ==NetworkInterfaceType.Ethernet )              
                        comboBox1.Items.Add(NetworkIntf.Name);               
            }
//如果有网卡，默认选中第一块网卡
            if (comboBox1.Items.Count > 0)
            {
                comboBox1.SelectedIndex = 0;
                GetNetInfor(comboBox1.SelectedItem.ToString());
            } public void GetNetInfor(string strNetAdapterName)
        {            
            //获取选中的网卡的IP，网关，子网掩码，DNS，备用DNS信息            
            NetworkInterface[] NetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
            foreach (NetworkInterface NetworkIntf in NetworkInterfaces)
            {
                if (NetworkIntf.Name == strNetAdapterName)
                {
                    IPInterfaceProperties IPInterfaceProperties = NetworkIntf.GetIPProperties();
                    //获取本机IP地址信息,子网掩码信息
                    UnicastIPAddressInformationCollection UnicastIPAddressInformationCollection = IPInterfaceProperties.UnicastAddresses;
                    if (UnicastIPAddressInformationCollection.Count > 0)
                    {
                        textBox1.Text = UnicastIPAddressInformationCollection[0].Address.ToString();
                        textBox2.Text = UnicastIPAddressInformationCollection[0].IPv4Mask.ToString();
                    }
                    else
                    {
                        textBox1.Text = "0.0.0.0";
                        textBox2.Text = "0.0.0.0";
                    }
                    //获取当前网关设置
                    GatewayIPAddressInformationCollection   GWAddress = IPInterfaceProperties.GatewayAddresses;
                    if (GWAddress.Count > 0)
                        textBox3.Text = GWAddress[0].Address.ToString();
                    else
                        textBox3.Text = "0.0.0.0";
                    //获取当前DNS设置
                    IPAddressCollection DNSAddress = IPInterfaceProperties.DnsAddresses;
                    switch (DNSAddress.Count )
                    {
                        case 1:
                            textBox4.Text = DNSAddress[0].ToString();
                            textBox5.Text = "0.0.0.0";
                            break;
                        case 2:                        
                            textBox4.Text = DNSAddress[0].ToString();
                            textBox5.Text = DNSAddress[1].ToString();
                            break;
                        default :
                            textBox4.Text = "0.0.0.0";
                            textBox5.Text = "0.0.0.0";
                            break;                       
                    }
                }
            }
        }

Answer 4

修改
自动获取
private ManagementBaseObject iObj = null;
        private ManagementBaseObject oObj = null;
        private ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
        private readonly ManagementObjectCollection moc;
        public void EnableDHCP()
        {
            foreach (ManagementObject mo in moc)
            {
                if (!(bool)mo["IPEnabled"]) continue;
                if (!(bool)mo["DHCPEnabled"])
                {
                    iObj = mo.GetMethodParameters("EnableDHCP");
                    oObj = mo.InvokeMethod("EnableDHCP", iObj, null);
                }
            }
        }
   public Form1()
        {
            InitializeComponent();
            moc = mc.GetInstances();
        }
        private void button3_Click(object sender, EventArgs e)
        {
            EnableDHCP();
        }另外用cmd命令自动获取private void button1_Click(object sender, EventArgs e)
        {
            string a = "set   address     name   =\"本地连接\"   source   =   dhcp";
            string b = "set   dns   name   =\"本地连接\"   source   =   dhcp";
            string c = "set   wins   name   =\"本地连接\"   source   =   dhcp";            Process p = new Process();
            p.StartInfo.FileName = "cmd.exe";
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true;
            p.Start();            p.StandardInput.WriteLine("netsh");
            p.StandardInput.WriteLine("interface");
            p.StandardInput.WriteLine("ip");
            p.StandardInput.WriteLine(a.ToString());
            p.StandardInput.WriteLine(b.ToString());
            p.StandardInput.WriteLine(c.ToString());
            p.StandardInput.WriteLine("exit");
            p.StandardInput.WriteLine("exit");
            p.Close();            
        }

Answer 6

用批的话就这样
@echo off
set /p a=请输入所要更改的IP
set /p b=请输入网关
netsh int ip set address %a% static %b% 1
