[ASP.net教程]C#获取设置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    /// </summary>    public void DisableAllAdapters()    {      // 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("Disable", null);      }    }
