获取IP和MAC
1. 在ASP.NET中专用属性：
获取服务器电脑名：Page.Server.ManchineName
获取用户信息：Page.User
获取客户端电脑名：Page.Request.UserHostName
获取客户端电脑IP：Page.Request.UserHostAddress
2. 在网络编程中的通用方法：
获取当前电脑名：static System.Net.Dns.GetHostName()
根据电脑名取出全部IP地址：static System.Net.Dns.Resolve(电脑名).AddressList
也可根据IP地址取出电脑名：static System.Net.Dns.Resolve(IP地址).HostName
3. 系统环境类的通用属性：
当前电脑名：static System.Environment.MachineName
当前电脑所属网域：static System.Environment.UserDomainName
当前电脑用户：static System.Environment.UserName
获取客户端IP:
using System.Net.NetworkInformation;
using System.Net.Sockets;
using System.Net;
1.
NetworkInterface[] NetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
int i=NetworkInterfaces.Length;
foreach (NetworkInterface NetworkIntf in NetworkInterfaces)
{
IPInterfaceProperties IPInterfaceProperties = NetworkIntf.GetIPProperties();
UnicastIPAddressInformationCollection UnicastIPAddressInformationCollection = IPInterfaceProperties.UnicastAddresses;
int j = UnicastIPAddressInformationCollection.Count;
foreach (UnicastIPAddressInformation UnicastIPAddressInformation in UnicastIPAddressInformationCollection)
{
if (UnicastIPAddressInformation.Address.AddressFamily == AddressFamily.InterNetwork)
{
Console.WriteLine(UnicastIPAddressInformation.Address);

else {
Console.WriteLine("不对！");
}
}
}
2.
IPHostEntry myHost = new IPHostEntry();
myHost = Dns.GetHostEntry(Dns.GetHostName());
for (int i = 0; i < myHost.AddressList.Length; i++)
{
string str = "本地主机IP地址->" + myHost.AddressList[i].ToString() + "\r";
}

System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;
获取MAC地址:
using System.Runtime.InteropServices;
[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=m
acinfo.ToString("X");
if(mac_src == "0")大连休闲
{
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！" + "<br>");
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));
}
}
}
Response.Write ("欢迎来自IP为"+userip+ "<br>" + ",MAC地址为"+mac_dest+"的朋友！"
+  "<br>");
}无法获取ip地址
catch(Exception err)
{
Response.Write(err.Message);
}
}
