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
