C#實現(xiàn)獲取設置IP地址小工具

更新時間：2015年06月16日 11:39:17 投稿：hebedich

c# 開發(fā)，方便更改IP地址。由于公司和家里的ip設置不一樣，公司要求手動設置，在家可以自動獲取IP，切都是無線網(wǎng)絡，為了方便操作，故做了這個小工具！

界面效果圖如下：

說下關鍵代碼

需要開啟 Windows Management Instrumentation服務（默認已經(jīng)開啟），在程序中需要增加 Management引用。

主要有NetworkAdapter（保存適配器的IP地址，網(wǎng)關，子網(wǎng)掩碼，設置IP方面等）,NetworkAdapterUtil(主要是NetworkAdapter類的集合 )兩個類。

在windows8 需要在app.manifest文件中

修改配置 <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />，不然就算有管理員權限也修改不了IP地址。

1 設置IP地址的代碼。（設置IP地址，修改IP地址需要管理員權限）

  /// <summary>
  /// 網(wǎng)絡適配器類
  /// </summary>
  public class NetworkAdapter
  { 

/// <summary>
    /// 設置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;
             //獲取操作設置IP的返回值， 可根據(jù)返回值去確認IP是否設置成功。 0或1表示成功 
            // 返回值說明網(wǎng)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 設置IP為自動獲取

   /// <summary>
    /// 啟用DHCP服務
    /// </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) //網(wǎng)卡接口標識是否相等, 相當只設置指定適配器IP地址
        {
          mo.InvokeMethod("SetDNSServerSearchOrder", null);
          mo.InvokeMethod("EnableDHCP", null);

        }
      }
    ｝

　　3. 獲取所有適配器

public class NetworkAdapterUtil
{


 /// <summary>
    /// 獲取所有適配器類型，適配器被禁用則不能獲取到
    /// </summary>
    /// <returns></returns>
    public List<NetworkAdapter> GetAllNetworkAdapters() //如果適配器被禁用則不能獲取到
    {
      IEnumerable<NetworkInterface> adapters = NetworkInterface.GetAllNetworkInterfaces(); //得到所有適配器
      return GetNetworkAdapters(adapters);

    }

 /// <summary>
   /// 根據(jù)條件獲取IP地址集合，
   /// </summary>
    /// <param name="adapters">網(wǎng)絡接口地址集合</param>
   /// <param name="adapterTypes">網(wǎng)絡連接狀態(tài)，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) //如果沒傳可選參數(shù)，就查詢所有
        {
          if (adapter != null)
          {
            NetworkAdapter adp = SetNetworkAdapterValue(adapter);
            adapterList.Add(adp);
          }
          else
          {
            return null;
          }
        }
        else //過濾查詢數(shù)據(jù)
        {
          foreach (NetworkInterfaceType networkInterfaceType in networkInterfaceTypes) 
          {           
            if (adapter.NetworkInterfaceType.ToString().Equals(networkInterfaceType.ToString())) 
            {
              adapterList.Add(SetNetworkAdapterValue(adapter)); 
              break; //退出當前循環(huán)
            }
          }
        }
      }
      return adapterList;
    ｝

 /// <summary>
   /// 設置網(wǎng)絡適配器信息
   /// </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;//網(wǎng)絡適配器標識符

     networkAdapter.Getwaryes = ips.GatewayAddresses; //網(wǎng)關地址集合
     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; //是否啟用DHCP服務

     IPInterfaceProperties adapterProperties = adapter.GetIPProperties();//獲取IPInterfaceProperties實例 
     networkAdapter.DnsAddresses = adapterProperties.DnsAddresses; //獲取并顯示DNS服務器IP地址信息 集合
     return networkAdapter;
   }
  }

 
｝

4 啟用，禁用適配器代碼

    /// <summary>
    /// 啟用所有適配器
    /// </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>
    /// 禁用所有適配器
    /// </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);
      }

    }
