c#使用windows的命令nbtstat获得MAC地址

        public static string GetRemoteMacByNetBIOS(string clientIP)

        {

            string ip = clientIP;

            if ( ip == "127.0.0.1")

                ip = GetLocalIP()[0];

            string dirResults="";

            ProcessStartInfo psi  = new ProcessStartInfo();

            Process proc = new Process();

            psi.FileName = "nbtstat.exe";

            //psi.RedirectStandardInput = false;

            psi.RedirectStandardOutput = true;psi.RedirectStandardError=true;

            psi.Arguments = "-A " + ip;

            psi.UseShellExecute = false;

            proc = Process.Start(psi);

            dirResults = proc.StandardOutput.ReadToEnd();

            string error = proc.StandardError.ReadToEnd();

            proc.WaitForExit();

            dirResults=dirResults.Replace("\r","").Replace("\n","").Replace("\t","");

 

            Regex reg=new Regex("Mac[ ]{0,}Address[ ]{0,}=[ ]{0,}(?((.)*?))__MAC",RegexOptions.IgnoreCase|RegexOptions.Compiled);

            Match mc=reg.Match(dirResults+"__MAC");

 

            if(mc.Success)

            {

                return mc.Groups["key"].Value.ToUpper();

            }

            else

            {                  

               return "";

            }

        }

使用此方法需要足够的操作系统的权限。在Web中,可以将ASP.net用户加入 管理员组。

对于上面两个地方都用到的GetLocalIP是一个获取本机IP的方法：

        public static string[] GetLocalIP()

        {

            string hostName = Dns.GetHostName();

            IPHostEntry ipEntry=Dns.GetHostByName(hostName);

            IPAddress[] arr=ipEntry.AddressList;

            string[] result = new string[arr.Length];

            for(int i=0;i

            {

                result[i] = arr[i].ToString(); 

            }

            return result;

        }
