C＃獲取本地IP（多個接口）本地MAC地址

Question

我有4個以太網接口，在我的電腦（獲得由ipconfig信息/全部）

例如：
1）IP：192.168.15.161 ，MAC：00-E2-4C-98-18-89
2）IP：172.168.11.126，MAC：00-FF-4C-98-18-44
3）IP：10.0.13.136，MAC：00-EE-89-98-13-44
4）IP：195.22.18.146，MAC：00-12-89-98-13-33

我需要一個返回功能給定IP時的MAC地址。

例如getMacByIP("192.168.15.161")將返回"00-E2-4C-98-18-89"

使用arp不工作的地方！

例如arp -a不會與MAC
給本地地址於是所有的問題/像here答案是沒有幫助我。

在問這個問題之前，我在網上搜了很多。

這個答案：（link）不幫助我

public static string GetMacAddressUsedByIp(string ipAddress) 
    { 
     var ips = new List<string>(); 
     string output; 

     try 
     { 
      // Start the child process. 
      Process p = new Process(); 
      // Redirect the output stream of the child process. 
      p.StartInfo.UseShellExecute = false; 

      p.StartInfo.RedirectStandardOutput = true; 
      p.StartInfo.UseShellExecute = false; 
      p.StartInfo.CreateNoWindow = true; 
      p.StartInfo.FileName = "ipconfig"; 
      p.StartInfo.Arguments = "/all"; 
      p.Start(); 
      // Do not wait for the child process to exit before 
      // reading to the end of its redirected stream. 
      // p.WaitForExit(); 
      // Read the output stream first and then wait. 
      output = p.StandardOutput.ReadToEnd(); 
      p.WaitForExit(); 

     } 
     catch 
     { 
      return null; 
     } 

     // pattern to get all connections 
     var pattern = @"(?xis) 
(?<Header> 
    (\r|\n) [^\r]+ : \r\n\r\n 
) 
(?<content> 
    .+? (?= ((\r\n\r\n)|($))) 
)"; 

     List<Match> matches = new List<Match>(); 

     foreach (Match m in Regex.Matches(output, pattern)) 
      matches.Add(m); 

     var connection = matches.Select(m => new 
     { 
      containsIp = m.Value.Contains(ipAddress), 
      containsPhysicalAddress = Regex.Match(m.Value, @"(?ix)Physical \s Address").Success, 
      content = m.Value 
     }).Where(x => x.containsIp && x.containsPhysicalAddress) 
     .Select(m => Regex.Match(m.content, @"(?ix) Physical \s address [^:]+ : \s* (?<Mac>[^\s]+)").Groups["Mac"].Value).FirstOrDefault(); 

     return connection; 
    } 

因爲如果我使用，例如，中國版本的Windows，正則表達式將無法正常工作！

這裏是一個建議的解決方案，做你的要求爲：

void Main() 
{ 
    Console.WriteLine(GetMacByIP("192.168.15.161")); // will return "00-E2-4C-98-18-89" 
} 

public string GetMacByIP(string ipAddress) 
{ 
    // grab all online interfaces 
    var query = NetworkInterface.GetAllNetworkInterfaces() 
     .Where(n => 
      n.OperationalStatus == OperationalStatus.Up && // only grabbing what's online 
      n.NetworkInterfaceType != NetworkInterfaceType.Loopback) 
     .Select(_ => new 
     { 
      PhysicalAddress = _.GetPhysicalAddress(), 
      IPProperties = _.GetIPProperties(), 
     }); 

    // grab the first interface that has a unicast address that matches your search string 
    var mac = query 
     .Where(q => q.IPProperties.UnicastAddresses 
      .Any(ua => ua.Address.ToString() == ipAddress)) 
     .FirstOrDefault() 
     .PhysicalAddress; 

    // return the mac address with formatting (eg "00-00-00-00-00-00") 
    return String.Join("-", mac.GetAddressBytes().Select(b => b.ToString("X2"))); 
}
