     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

        /// 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="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; }
