C#设置ip地址，启用禁用适配器

界面效果图如下：

报表界面

说下关键代码

需要开启Windows Management Instrumentation服务（默认已经开启），在程序中需要增加Management引用。

主要有NetworkAdapter（保存适配器的IP地址，网关，子网掩码，设置IP方面等 ）,NetworkAdapterUtil(主要是NetworkAdapter类的集合 )两个类。

在windows8 需要在app.manifest文件中

修改配置 <requestedExecutionLevel level="requireAdministrator" uiaccess="false" />，不然就算有管理员权限也修改不了IP地址。

1 设置IP地址的代码。（设置IP地址，修改IP地址需要管理员权限）

    /// <summary>    /// 网络适配器类    /// </summary>    public class NetworkAdapter    { /// <summary>        /// 设置IP地址        /// </summary>        /// <param name="ip"></param>        /// <param name="submask"></param>        /// <param name="getway"></param>        /// <param name="dns"></param>        PRivate bool SetIPAddress(string[] ip, string[] submask, string[] getway, string[] dns)        {            ManagementClass wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");            ManagementObjectCollection moc = wmi.GetInstances();            ManagementBaSEObject inPar = null;            ManagementBaseObject outPar = null;            string str = "";            foreach (ManagementObject mo in moc)            {                if (!(bool)mo["IPEnabled"])                    continue;                              if (this.NetworkInterfaceID == mo["SettingID"].ToString())                {                    if (ip != null && submask != null)                    {                        string caption = mo["Caption"].ToString(); //描述                        inPar = mo.GetMethodParameters("EnableStatic");                        inPar["IPAddress"] = ip;                        inPar["SubnetMask"] = submask;                        outPar = mo.InvokeMethod("EnableStatic", inPar, null);                        str = outPar["returnvalue"].ToString();                        return (str=="0"||str=="1")?true:false;                         //获取操作设置IP的返回值， 可根据返回值去确认IP是否设置成功。 0或1表示成功                         // 返回值说明网址： https://msdn.microsoft.com/en-us/library/aa393301(v=vs.85).aspx                    }                    if(getway!=null)                    {                        inPar = mo.GetMethodParameters("SetGateways");                        inPar["DefaultIPGateway"] = getway;                        outPar = mo.InvokeMethod("SetGateways", inPar, null);                        str = outPar["returnvalue"].ToString();                        return (str == "0" || str == "1") ? true : false;                    }                    if (dns != null)                    {                        inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");                        inPar["DNSServerSearchOrder"] = dns;                        outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);                        str = outPar["returnvalue"].ToString();                        return (str == "0" || str == "1") ? true : false;                    }                                   }            }            return false;        } ｝

2 设置IP为自动获取

     /// <summary>        /// 启用DHCP服务        /// </summary>        public void EnableDHCP()        {            ManagementClass wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");            ManagementObjectCollection moc = wmi.GetInstances();            foreach (ManagementObject mo in moc)            {                if (!(bool)mo["IPEnabled"])                    continue;                if (mo["SettingID"].ToString() == this.NetworkInterfaceID) //网卡接口标识是否相等, 相当只设置指定适配器IP地址                {                    mo.InvokeMethod("SetDNSServerSearchOrder", null);                    mo.InvokeMethod("EnableDHCP", null);                }            }        ｝

　　3. 获取所有适配器

public class NetworkAdapterUtil{ /// <summary>       /// 获取所有适配器类型，适配器被禁用则不能获取到       /// </summary>       /// <returns></returns>       public List<NetworkAdapter> GetAllNetworkAdapters() //如果适配器被禁用则不能获取到       {           IEnumerable<NetworkInterface> adapters = NetworkInterface.GetAllNetworkInterfaces(); //得到所有适配器           return GetNetworkAdapters(adapters);       } /// <summary>      /// 根据条件获取IP地址集合，      /// </summary>       /// <param name="adapters">网络接口地址集合</param>      /// <param name="adapterTypes">网络连接状态，如,UP,DOWN等</param>      /// <returns></returns>       private List<NetworkAdapter> GetNetworkAdapters(IEnumerable<NetworkInterface> adapters, params NetworkInterfaceType[] networkInterfaceTypes)        {            adapterList = new List<NetworkAdapter>();            foreach (NetworkInterface adapter in adapters)            {                if (networkInterfaceTypes.Length <=0) //如果没传可选参数，就查询所有                {                    if (adapter != null)                    {                        NetworkAdapter adp = SetNetworkAdapterValue(adapter);                        adapterList.Add(adp);                    }                    else                    {                        return null;                    }                }                else //过滤查询数据                {                   foreach (NetworkInterfaceType networkInterfaceType in networkInterfaceTypes)                     {                                            if (adapter.NetworkInterfaceType.ToString().Equals(networkInterfaceType.ToString()))                         {                            adapterList.Add(SetNetworkAdapterValue(adapter));                             break; //退出当前循环                        }                    }                }            }            return adapterList;        ｝  /// <summary>      /// 设置网络适配器信息      /// </summary>      /// <param name="adapter"></param>      /// <returns></returns>      private NetworkAdapter SetNetworkAdapterValue(NetworkInterface adapter)      {          NetworkAdapter networkAdapter = new NetworkAdapter();          IPInterfaceProperties ips = adapter.GetIPProperties();          networkAdapter.Description = adapter.Name;          networkAdapter.NetworkInterfaceType = adapter.NetworkInterfaceType.ToString();          networkAdapter.Speed = adapter.Speed / 1000 / 1000 + "MB"; //速度          networkAdapter.MacAddress = adapter.GetPhysicalAddress(); //物理地址集合          networkAdapter.NetworkInterfaceID = adapter.Id;//网络适配器标识符          networkAdapter.Getwaryes = ips.GatewayAddresses; //网关地址集合          networkAdapter.IPAddresses = ips.UnicastAddresses; //IP地址集合          networkAdapter.DhcpServerAddresses = ips.DhcpServerAddresses;//DHCP地址集合          networkAdapter.IsDhcpEnabled =ips.GetIPv4Properties()==null?false: ips.GetIPv4Properties().IsDhcpEnabled; //是否启用DHCP服务          IPInterfaceProperties adapterProperties = adapter.GetIPProperties();//获取IPInterfaceProperties实例            networkAdapter.DnsAddresses = adapterProperties.DnsAddresses; //获取并显示DNS服务器IP地址信息 集合          return networkAdapter;      }    }  ｝

4 启用， 禁用适配器代码

       /// <summary>       /// 启用所有适配器       /// </summary>       /// <returns></returns>       public void  EnableAllAdapters()       {          // ManagementClass wmi = new ManagementClass("Win32_NetworkAdapter");          // ManagementObjectCollection moc = wmi.GetInstances();           System.Management.ManagementObjectSearcher moc = new System.Management.ManagementObjectSearcher("Select * from Win32_NetworkAdapter where NetEnabled!=null ");                foreach (System.Management.ManagementObject mo in moc.Get())           {               //if (!(bool)mo["NetEnabled"])               //    continue;               string capation = mo["Caption"].ToString();               string descrption =mo["Description"].ToString();               mo.InvokeMethod("Enable",null);           }                 }       /// <summary>       /// 禁用所有适配器       /// </s
