MAC address to IP Address on Same LAN in C#
提问by Kazoom
Is there a way to find mapping between MAC address to IP address in C#. i think RARP should be able to do that, is there an API available in C# for that
有没有办法在 C# 中找到 MAC 地址到 IP 地址之间的映射。我认为 RARP 应该能够做到这一点，C# 中是否有可用的 API

Why not spawn a process to invoke rarpand read in the input stream from the process's output? That's a real cheap simple and cheerful way of doing it...top-of-my-head, it goes something like this:
为什么不产生一个进程来调用rarp和从进程的输出中读取输入流？这是一种真正便宜的简单而愉快的方法……在我的脑海中，它是这样的：
System.Diagnostics.ProcessStartInfo ps = new System.Diagnostics.ProcessStartInfo("arp", "-a");
ps.CreateNoWindow = false;
ps.RedirectStandardOutput = true;
using (System.Diagnostics.Process proc = new System.Diagnostics.Process())
{
proc.StartInfo = ps;
proc.Start();
System.IO.StreamReader sr = proc.StandardOutput;
while (!proc.HasExited) ;
string sResults = sr.ReadToEnd();
}
Then it's a matter of parsing the sResultsto get the MAC address.
然后就是解析sResults得到MAC地址的问题。

You can use this class
你可以使用这个类
internal class IPAndMac
{
public string IP { get; set; }
public string MAC { get; set; }
}
public class IPMacMapper
{
private static List<IPAndMac> list;
private static StreamReader ExecuteCommandLine(String file, String arguments = "")
{
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.CreateNoWindow = true;
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.FileName = file;
startInfo.Arguments = arguments;
Process process = Process.Start(startInfo);
return process.StandardOutput;
}
private static void InitializeGetIPsAndMac()
{
if (list != null)
return;
var arpStream = ExecuteCommandLine("arp", "-a");
List<string> result = new List<string>();
while (!arpStream.EndOfStream)
{
var line = arpStream.ReadLine().Trim();
result.Add(line);
}
list = result.Where(x => !string.IsNullOrEmpty(x) && (x.Contains("dynamic") || x.Contains("static")))
.Select(x =>
{
string[] parts = x.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);
return new IPAndMac { IP = parts[0].Trim(), MAC = parts[1].Trim() };
}).ToList();
}
public static string FindIPFromMacAddress(string macAddress)
{
InitializeGetIPsAndMac();
return list.SingleOrDefault(x => x.MAC == macAddress).IP;
}
public static string FindMacFromIPAddress(string ip)
{
InitializeGetIPsAndMac();
return list.SingleOrDefault(x => x.IP == ip).MAC;
}
}
and use it as
并将其用作
var ipAddress = IPMacMapper.FindIPFromMacAddress("mac-address");
var macAddress = IPMacMapper.FindMacFromIPAddress("ip-address");

In case you are looking for an API based approach and are not able to do a Process.Start() take a look at this:
如果您正在寻找基于 API 的方法并且无法执行 Process.Start() ，请查看以下内容：
http://www.codeproject.com/KB/IP/host_info_within_network.aspx
http://www.codeproject.com/KB/IP/host_info_within_network.aspx
It allows mapping of hostname, IP address and MAC address.
它允许映射主机名、IP 地址和 MAC 地址。
