本文告訴大家如何在 dotnet core 獲取 Mac 地址

因?yàn)樵?dotnetcore 是沒有直接和硬件相關(guān)的，所以無法通過 WMI 的方法獲取當(dāng)前設(shè)備的 Mac 地址

但是在 dotnet core 可以使用下面的代碼拿到本機(jī)所有的網(wǎng)卡地址，包括物理網(wǎng)卡和虛擬網(wǎng)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(yùn)行代碼，下面是控制臺(tái)

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(wǎng)卡，從堆棧網(wǎng)找到的方法獲取當(dāng)前有活躍的 ip 的網(wǎng)卡可以通過先判斷是不是本地巡回網(wǎng)絡(luò)等，然后判斷有沒有網(wǎng)絡(luò)

foreach (NetworkInterface adapter in nics.Where(c =>
 c.NetworkInterfaceType != NetworkInterfaceType.Loopback && c.OperationalStatus == OperationalStatus.Up))

獲取當(dāng)前的網(wǎng)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(gè)才是需要的網(wǎng)卡
 }

簡(jiǎn)單輸出網(wǎng)卡使用 adapter.GetPhysicalAddress().ToString() 輸出，如果需要輸出帶連接的請(qǐng)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(diào)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(shí)輸出是一個(gè)網(wǎng)卡

NetworkInterface.GetPhysicalAddress Method (System.Net.NetworkInformation)

PhysicalAddress Class (System.Net.NetworkInformation)
