asp.net 获取客户端IP与mac(MSN)

获取客户端IP:

以下为引用的内容： private string GetClientIP()

   {

   string result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

   if (null == result || result == String.Empty)

   {

     result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

   }

asp?date=11-24&s=1227514233" class="logo" border="0" onload="return imgzoom(this,550);" style="cursor: pointer;" onclick="javascript:window.open(this.src);"/>   if (null == result || result == String.Empty)

   {

     result = HttpContext.Current.Request.UserHostAddress;

   }

   return result;

   }

获取MAC地址:

以下为引用的内容： DllImport("Iphlpapi.dll")]

   private static extern int SendARP(Int32 dest,Int32 host,ref Int64 mac,ref Int32 length);

   [DllImport("Ws2_32.dll")]

   private static extern Int32 inet_addr(string ip);

   private void Page_Load(object sender, System.EventArgs e)

   {

   // 在此处放置用户代码以初始化页面

   try

   {

     string userip=Request.UserHostAddress;

     string strClientIP = Request.UserHostAddress.ToString().Trim();

     Int32 ldest = inet_addr(strClientIP); //目的地的ip

     Int32 lhost = inet_addr("");   //本地服务器的ip

     Int64 macinfo = new Int64();

     Int32 len = 6;

     int res = SendARP(ldest,0, ref macinfo, ref len);

     string mac_src=macinfo.ToString("X");

     if(mac_src == "0")

     {

     if(userip=="127.0.0.1")

       Response.Write ("正在访问Localhost!");

     else

       Response.Write ("欢迎来自IP为" + userip + "的朋友！" + "

");

     return;

     }

     while(mac_src.Length<12)

     {

     mac_src = mac_src.Insert(0,"0");

     }

     string mac_dest="";

     for(int i=0;i<11;i++)

     {

     if (0 == (i % 2))

     {

       if ( i == 10 )

       {

       mac_dest = mac_dest.Insert(0,mac_src.Substring(i,2));

       }

       else

       {

       mac_dest ="-" + mac_dest.Insert(0,mac_src.Substring(i,2));

       }

     }

     }

­

//方法二

using System.Text.RegularExpressions;

using System.Diagnostics;

public class test

{

         public test

         {}

         public static string GetCustomerMac(string IP) //para IP is the client's IP

         {

               string dirResults="";

               ProcessStartInfo psi   = new ProcessStartInfo();

               Process proc = new Process();

               psi.FileName = "nbtstat";

               psi.RedirectStandardInput = false;

               psi.RedirectStandardOutput = true;

               psi.Arguments = "-A " + IP;

               psi.UseShellExecute = false;

               proc = Process.Start(psi);

               dirResults = proc.StandardOutput.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;

           }

             else

           {

                 reg=new Regex("Host not found",RegexOptions.IgnoreCase|RegexOptions.Compiled);

                 mc=reg.Match(dirResults);

             if(mc.Success)

             {

                 return "Host not found!";

             }

             else

             {

                 return "";

             }

       }

   }

}

这种方法有些地方得好好摸索，不然看不懂的

获取服务器的IP地址方法以DNS法较为简单实用，如下：

   using System.Net;

­

private void ButtonIP_Click(object sender, System.EventArgs e)

   {  

     System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;

     if ( addressList.Length>1)

     {   TextLIP.Text = addressList[0].ToString();

           TextSIP.Text = addressList[1].ToString();

     }

     else

     {

           TextLIP.Text = addressList[0].ToString();

           TextSIP.Text = "没有可用的连接";

     }

   }

获取服务器的IP地址与MAC地址另一方法如下：

­

­

以下为引用的内容：     using System.Management;

­

   string stringMAC = "";

   string stringIP = "";

   ManagementClass MC = new ManagementClass "Win32_NetworkAdapterConfiguration");

   ManagementObjectCollection MOC= MC.GetInstances();

  

   foreach(ManagementObject MO in MOC)

   {

     if ((bool)MO["IPEnabled"] == true)

     {

     stringMAC += MO["MACAddress"].ToString();

     TextMAC.Text = stringMAC.ToString();

     string[] IPAddresses = (string[]) MO["IPAddress"];

     if(IPAddresses.Length > 0)

     stringIP = IPAddresses[0];

     TextIP.Text = stringIP.ToString();

     }

   }

获取客户端本机的IP地址相当简易，方法如下：

以下为引用的内容： using System.Net;

­

TextIP.Text=Page.Request.UserHostAddress;

如要获取客户端本机的MAC地址就相对复杂些，得导入调用两个API
