C#中获取服务器IP，客户端IP以及网卡物理地址

 客户端ip:
 Request.ServerVariables.Get("Remote_Addr").ToString();
 客户端主机名:
 Request.ServerVariables.Get("Remote_Host").ToString();
 客户端浏览器IE：
 Request.Browser.Browser;
 客户端浏览器 版本号：
 Request.Browser.MajorVersion;
 客户端操作系统：
 Request.Browser.Platform;
 服务器ip:
 Request.ServerVariables.Get("Local_Addr").ToString();
 服务器名：
 Request.ServerVariables.Get("Server_Name").ToString();
 如果你想进一步了解ServerVariables，可以用
 foreach(String o in Request.ServerVariables){
 Response.Write(o+"="+Request.ServerVariables[o]+"<br>");
 }
 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(); //获取网卡的地址
        string[] IPAddresses = (string[]) MO["IPAddress"]; //获取本地的IP地址
        if(IPAddresses.Length > )
        stringIP = IPAddresses[];
        Response.Write(stringMAC+"/"+stringIP);
      }
    }
 asp.net+c#如何获取客户端网卡的MAC地址？
 //要引用到以下两个命名空间
 using System.Diagnostics;
 using System.Text.RegularExpressions;

 //获取远程客户端的网卡物理地址（MAC）
 public string GetMac(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,}(?<key>((.)*?))__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 "";
 }
 }
 }

 //在页面上打印出客户端的网卡物理地址（MAC）
 Response.Write(this.GetMac(Request.UserHostAddress.ToString()));

  获取cpu序列号,硬盘ID,网卡MAC地址
 private void GetInfo()
   {
    string cpuInfo = "";//cpu序列号
    ManagementClass cimobject = new ManagementClass("Win32_Processor");
    ManagementObjectCollection moc = cimobject.GetInstances();
    foreach(ManagementObject mo in moc)
    {
     cpuInfo = mo.Properties["ProcessorId"].Value.ToString();
     Response.Write ("cpu序列号："+cpuInfo.ToString ());
    }

    //获取硬盘ID
    String HDid;
    ManagementClass cimobject1 = new ManagementClass("Win32_DiskDrive");
    ManagementObjectCollection moc1 = cimobject1.GetInstances();
    foreach(ManagementObject mo in moc1)
    {
     HDid = (string)mo.Properties["Model"].Value;
     Response.Write ("硬盘序列号："+HDid.ToString ());
    }

    //获取网卡硬件地址

    ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
    ManagementObjectCollection moc2 = mc.GetInstances();
    foreach(ManagementObject mo in moc2)
    {
     if((bool)mo["IPEnabled"] == true)
      Response.Write("MAC address\t{0}"+mo["MacAddress"].ToString());
     mo.Dispose();
    }
   }
