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); } }
