這篇文章將為大家詳細講解有關如何在asp.net項目中獲取 MacAddress 地址,文章內容質量較高,因此小編分享給大家做個參考,希望大家閱讀完這篇文章后對相關知識有一定的了解。
因為在 dotnetcore 是沒有直接和硬件相關的,所以無法通過 WMI 的方法獲取當前設備的 Mac 地址
但是在 dotnet core 可以使用下面的代碼拿到本機所有的網卡地址,包括物理網卡和虛擬網卡
IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties(); NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces(); Console.WriteLine("Interface information for {0}.{1} ", computerProperties.HostName, computerProperties.DomainName); if (nics == null || nics.Length < 1) { Console.WriteLine(" No network interfaces found."); return; } Console.WriteLine(" Number of interfaces .................... : {0}", nics.Length); foreach (NetworkInterface adapter in nics) { Console.WriteLine(); Console.WriteLine(adapter.Name + "," + adapter.Description); Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length, '=')); Console.WriteLine(" Interface type .......................... : {0}", adapter.NetworkInterfaceType); Console.Write(" Physical address ........................ : "); PhysicalAddress address = adapter.GetPhysicalAddress(); byte[] bytes = address.GetAddressBytes(); for (int i = 0; i < bytes.Length; i++) { // Display the physical address in hexadecimal. Console.Write("{0}", bytes[i].ToString("X2")); // Insert a hyphen after each byte, unless we are at the end of the // address. if (i != bytes.Length - 1) { Console.Write("-"); } } Console.WriteLine(); }
運行代碼,下面是控制臺
Interface information for lindexi.github Number of interfaces .................... : 6 Hyper-V Virtual Ethernet Adapter #4 =================================== Interface type .......................... : Ethernet Physical address ........................ : 00-15-5D-96-39-03 Hyper-V Virtual Ethernet Adapter #3 =================================== Interface type .......................... : Ethernet Physical address ........................ : 1C-1B-0D-3C-47-91 Software Loopback Interface 1 ============================= Interface type .......................... : Loopback Physical address ........................ : Microsoft Teredo Tunneling Adapter ================================== Interface type .......................... : Tunnel Physical address ........................ : 00-00-00-00-00-00-00-E0 Hyper-V Virtual Ethernet Adapter ================================ Interface type .......................... : Ethernet Physical address ........................ : 5A-15-31-73-B0-9F Hyper-V Virtual Ethernet Adapter #2 =================================== Interface type .......................... : Ethernet Physical address ........................ : 5A-15-31-08-13-B1
但是可以看到里面有很多不需要使用的網卡,從 堆棧 網找到的方法獲取當前有活躍的 ip 的網卡可以通過先判斷是不是本地巡回網絡等,然后判斷有沒有網絡
foreach (NetworkInterface adapter in nics.Where(c => c.NetworkInterfaceType != NetworkInterfaceType.Loopback && c.OperationalStatus == OperationalStatus.Up))
獲取當前的網卡有沒 ip 有 ip 才是需要的
IPInterfaceProperties properties = adapter.GetIPProperties(); var unicastAddresses = properties.UnicastAddresses; foreach (var temp in unicastAddresses.Where(temp => temp.Address.AddressFamily == AddressFamily.InterNetwork)) { // 這個才是需要的網卡 }
簡單輸出網卡使用 adapter.GetPhysicalAddress().ToString() 輸出,如果需要輸出帶連接的請使用 GetAddressBytes 然后自己輸出
下面的代碼是我抽出來的,可以直接使用
public static void GetActiveMacAddress(string separator = "-") { NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces(); //Debug.WriteLine("Interface information for {0}.{1} ", // computerProperties.HostName, computerProperties.DomainName); if (nics == null || nics.Length < 1) { Debug.WriteLine(" No network interfaces found."); return; } var macAddress = new List<string>(); //Debug.WriteLine(" Number of interfaces .................... : {0}", nics.Length); foreach (NetworkInterface adapter in nics.Where(c => c.NetworkInterfaceType != NetworkInterfaceType.Loopback && c.OperationalStatus == OperationalStatus.Up)) { //Debug.WriteLine(""); //Debug.WriteLine(adapter.Name + "," + adapter.Description); //Debug.WriteLine(string.Empty.PadLeft(adapter.Description.Length, '=')); //Debug.WriteLine(" Interface type .......................... : {0}", adapter.NetworkInterfaceType); //Debug.Write(" Physical address ........................ : "); //PhysicalAddress address = adapter.GetPhysicalAddress(); //byte[] bytes = address.GetAddressBytes(); //for (int i = 0; i < bytes.Length; i++) //{ // // Display the physical address in hexadecimal. // Debug.Write($"{bytes[i]:X2}"); // // Insert a hyphen after each byte, unless we are at the end of the // // address. // if (i != bytes.Length - 1) // { // Debug.Write("-"); // } //} //Debug.WriteLine(""); //Debug.WriteLine(address.ToString()); IPInterfaceProperties properties = adapter.GetIPProperties(); var unicastAddresses = properties.UnicastAddresses; if (unicastAddresses.Any(temp => temp.Address.AddressFamily == AddressFamily.InterNetwork)) { var address = adapter.GetPhysicalAddress(); if (string.IsNullOrEmpty(separator)) { macAddress.Add(address.ToString()); } else { macAddress.Add(string.Join(separator, address.GetAddressBytes())); } } } }
上面的方法不僅是在 dotnet core 可以使用,在 dotnet framework 程序同樣調用,但是在 dotnet framework 還可以通過 WMI 獲取
在 dotnet framework 使用 WMI 獲取 MAC 地址方法
var managementClass = new ManagementClass("Win32_NetworkAdapterConfiguration"); var managementObjectCollection = managementClass.GetInstances(); foreach (var managementObject in managementObjectCollection.OfType<ManagementObject>()) { using (managementObject) { if ((bool) managementObject["IPEnabled"]) { if (managementObject["MacAddress"] == null) { return string.Empty; } return managementObject["MacAddress"].ToString().ToUpper(); } } }
輸出的格式是 5A:15:31:73:B0:9F 同時輸出是一個網卡
NetworkInterface.GetPhysicalAddress Method (System.Net.NetworkInformation)
PhysicalAddress Class (System.Net.NetworkInformation)
