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

为什么不生成一个进程来调用rarp
并从进程的输出中读入输入流?这是一种真正廉价的简单而愉快的方式......我的头脑,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(); }
然后解析sResults
以获取MAC地址。

您可以使用此课程
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;
}
}
并将其用作
var ipAddress = IPMacMapper.FindIPFromMacAddress("mac-address");
var macAddress = IPMacMapper.FindMacFromIPAddress("ip-address");

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:

它允许映射主机名,IP地址和MAC地址。
