C#的网络适配器操作

网络的相关设置在项目开发中有较多的应用，有时候需要在项目中对网络信息进行相关设置。

现在提供提供几种相关的辅助方法类。

(1).IP地址

        /// <summary>/// IP地址/// </summary>public string IpAddress{get{string ipAddress;var address = GetAddress();if (address == null){ipAddress = string.Empty;}else{ipAddress = address.Address.ToString();}return ipAddress;}set { if (value == null) throw new ArgumentNullException(nameof(value)); }}

(2).网关地址

        /// <summary>/// 网关地址/// </summary>public string Getway{get{              string getway;if (Getwaryes != null && Getwaryes.Count > 0){getway = Getwaryes[0].Address.ToString() == "0.0.0.0" ? "" : Getwaryes[0].Address.ToString(); }else{getway =string.Empty;}return getway;}set { if (value == null) throw new ArgumentNullException(nameof(value)); }}

(3). DHCP服务器地址

       /// <summary>/// DHCP服务器地址/// </summary>public string DhcpServer{get{string dhcpServer;if (DhcpServerAddresses != null && DhcpServerAddresses.Count > 0){dhcpServer = DhcpServerAddresses[0].ToString();}else{dhcpServer = string.Empty;}return dhcpServer;}set { if (value == null) throw new ArgumentNullException(nameof(value)); }}

(4).MAC地址

        /// <summary>/// MAC地址/// </summary>public string MacAddres{get{string macAddress;if (MacAddress == null)macAddress = string.Empty;else if (MacAddress.ToString().Length == 12){macAddress = MacAddress.ToString().Insert(4, "-").Insert(9, "-");}else{macAddress = MacAddress.ToString();}return macAddress;}set { if (value == null) throw new ArgumentNullException(nameof(value)); }}

(5). 主DNS地址

        /// <summary>/// 主DNS地址/// </summary>public string DnsMain{get{var dnsMain =string.Empty;if (DnsAddresses.Count > 0){if (IsIPAddress(DnsAddresses[0].ToString())){dnsMain = DnsAddresses[0].ToString();}}else{dnsMain =string.Empty;}return dnsMain;}set { if (value == null) throw new ArgumentNullException(nameof(value)); }}

(6).备用DNS地址

        /// <summary>/// 备用DNS地址/// </summary>public string DnsBackup{get{var dnsBackup = string.Empty;if (DnsAddresses.Count > 1){if (IsIPAddress(DnsAddresses[1].ToString())){dnsBackup = DnsAddresses[1].ToString();}}else{dnsBackup = string.Empty;}return dnsBackup;}set { if (value == null) throw new ArgumentNullException(nameof(value)); }}

(7).子网掩码

        /// <summary>/// 子网掩码/// </summary>public string Mask{get{string mask;var address = GetAddress();if (address == null){mask = "";}else{if (address.IPv4Mask != null) {mask = address.IPv4Mask.ToString();}else{mask = "255.255.255.0";}}return mask;}set { if (value == null) throw new ArgumentNullException(nameof(value)); }}

(8).属性

       /// <summary>/// DNS集合/// </summary>public IPAddressCollection DnsAddresses { get; set; }/// <summary>/// 网关地址集合/// </summary>public GatewayIPAddressInformationCollection Getwaryes { get; set; }/// <summary>/// IP地址集合/// </summary>public UnicastIPAddressInformationCollection IpAddresses { get; set; }/// <summary>/// DHCP地址集合/// </summary>public IPAddressCollection DhcpServerAddresses { get; set; }/// <summary>/// 网卡MAC地址/// </summary>public PhysicalAddress MacAddress { get; set; }/// <summary>/// 是否启用DHCP服务/// </summary>public bool IsDhcpEnabled { get; set; }/// <summary>/// 描述信息/// </summary>public string Description { get; set; }/// <summary>/// 网络接口类型/// </summary>/// <returns></returns>public string NetworkInterfaceType { get; set; }/// <summary>/// 速度/// </summary>public string Speed { get; set; }

(9).是否是IP地址

        /// <summary>/// 是否是IP地址/// </summary>/// <param name="ipAddress"></param>/// <returns></returns>public bool IsIPAddress(string ipAddress){const string regexStr = @"^(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])$";var regex = System.Text.RegularExpressions.Regex.Match(ipAddress, regexStr);return regex.Success;}

(10).启用DHCP服务

        /// <summary>/// 启用DHCP服务/// </summary>public bool EnableDhcp(){var wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");var moc = wmi.GetInstances();foreach (var o in moc){var mo = (ManagementObject) o;if (!(bool)mo["IPEnabled"])continue;if (mo["SettingID"].ToString() != NetworkInterfaceId) continue;mo.InvokeMethod("SetDNSServerSearchOrder", null);mo.InvokeMethod("EnableDHCP", null);}//查询现适配器接口信息var networkAdapter = new NetworkAdapterUtil().GetNeworkAdapterByNetworkInterfaceId(NetworkInterfaceId); return networkAdapter != null && networkAdapter.IsDhcpEnabled;}

(11).设置IP地址,子网掩码，网关,DNS

        /// <summary>/// 设置IP地址,子网掩码，网关,DNS,/// </summary>public bool SetIpAddressSubMaskDnsGetway(string ipAddress, string subMask, string getWay, string dnsMain, string dnsBackup){string[] dnsArray;if (string.IsNullOrEmpty(dnsBackup)){dnsArray = new[] { dnsMain };}else{dnsArray = new[] { dnsMain, dnsBackup };}return SetIpAddress(new[] { ipAddress }, new[] { subMask }, new[] { getWay }, dnsArray);}/// <summary>/// 设置IP地址和子网掩码/// </summary>public bool SetIpAddressAndSubMask(string ipAddress, string subMask){return SetIpAddress(new[] { ipAddress }, new[] { subMask }, null, null);}/// <summary>/// 设置IP网关/// </summary>public bool SetGetWayAddress(string getWay){return SetIpAddress(null, null, new[] { getWay }, null);}

(12).设置主,备份DNS地址

        /// <summary>/// 设置主,备份DNS地址/// </summary>public bool SetDnsAddress(string dnsMain, string dnsBackup){string[] dnsArray;if (string.IsNullOrEmpty(dnsBackup)){dnsArray = new[] { dnsMain };}else{dnsArray = new[] { dnsMain, dnsBackup };}return  SetIpAddress(null, null, null, dnsArray);}

(13).得到IPV4地址

        /// <summary>/// 得到IPV4地址/// </summary>/// <returns></returns>private UnicastIPAddressInformation GetAddress(){if (IpAddresses == null || IpAddresses.Count <= 0) return null;switch (IpAddresses.Count){case 3:return IpAddresses[2];case 2:return IpAddresses[1];}return IpAddresses[0];}

(14).检查设置IP地址,如果返回空，表示检查通过，为了方便返回就字符串了

        /// <summary>/// 检查设置IP地址,如果返回空，表示检查通过，为了方便返回就字符串了，没用枚举了/// </summary>/// <param name="ipAddress"></param>/// <param name="subMask"></param>/// <param name="getWay"></param>/// <param name="dnsMain"></param>/// <param name="dnsBackup"></param>/// <returns></returns>public string IsIPAddress(string ipAddress, string subMask, string getWay, string dnsMain, string dnsBackup){if (!string.IsNullOrEmpty(ipAddress)){if (!IsIPAddress(ipAddress)) return "IP地址格式不对";}if (!string.IsNullOrEmpty(subMask)){if (!IsIPAddress(subMask)) return "子网掩码格式不对";}if (!string.IsNullOrEmpty(getWay)){if (!IsIPAddress(getWay)) return "网关地址格式不对";}if (!string.IsNullOrEmpty(dnsMain)){if (!IsIPAddress(dnsMain)) return "主DNS地址格式不对";}if (string.IsNullOrEmpty(dnsBackup)) return "";return !IsIPAddress(dnsBackup) ? "备用DNS地址格式不对" : "";}

(15).设置IP地址

        /// <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(IEnumerable ip, IEnumerable submask, IEnumerable getway, IEnumerable dns){var wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");var moc = wmi.GetInstances();foreach (var o in moc){var mo = (ManagementObject) o;if (!(bool)mo["IPEnabled"])continue;if (NetworkInterfaceId != mo["SettingID"].ToString()) continue;ManagementBaseObject inPar;ManagementBaseObject outPar;string str = null;if (ip != null && submask != null){inPar = mo.GetMethodParameters("EnableStatic");inPar["IPAddress"] = ip;inPar["SubnetMask"] = submask;outPar = mo.InvokeMethod("EnableStatic", inPar, null);if (outPar != null) str = outPar["returnvalue"].ToString();return (str=="0"||str=="1");//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
                }if(getway!=null){inPar = mo.GetMethodParameters("SetGateways");inPar["DefaultIPGateway"] = getway;outPar = mo.InvokeMethod("SetGateways", inPar, null);if (outPar != null) str = outPar["returnvalue"].ToString();return (str == "0" || str == "1");}if (dns == null) continue;inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");inPar["DNSServerSearchOrder"] = dns;outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);if (outPar != null) str = outPar["returnvalue"].ToString();return (str == "0" || str == "1");}return false;}
