網絡的相關設置在項目開發中有較多的應用，有時候需要在項目中對網絡信息進行相關設置。
現在提供提供幾種相關的輔助方法類。
(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).網關地址
/// <summary> /// 網關地址 /// </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服務器地址
/// <summary> /// DHCP服務器地址 /// </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> /// 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).備用DNS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).啟用DHCP服務
/// <summary> /// 啟用DHCP服務 /// </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); } //查詢現適配器接口信息 var networkAdapter = new NetworkAdapterUtil().GetNeworkAdapterByNetworkInterfaceId(NetworkInterfaceId); return networkAdapter != null && networkAdapter.IsDhcpEnabled; }(11).設置IP地址,子網掩碼，網關,DNS
