1. 在ASP.NET中专用属性:
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;

NetworkInterface[] NetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
int i=NetworkInterfaces.Length;
foreach (NetworkInterface NetworkIntf in NetworkInterfaces)
暴风男{

UnicastIPAddressInformationCollection UnicastIPAddressInformationCollection = IPInterfaceProperties.UnicastAddresses;
int j = UnicastIPAddressInformationCollection.Count;
foreach (UnicastIPAddressInformation UnicastIPAddressInformation in UnicastIPAddressInformationCollection)
刘洋演员{
if (UnicastIPAddressInformation.Address.AddressFamily == AddressFamily.InterNetwork)
