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
一个获取本机内网和外网IP的公用类
using System; using System.IO; using System.Net; using System.Text; using System.Text.RegularExpressions; namespace ipip { /// <summary> /// Class1 的摘要说明。 /// 获取本机上网IP和内网IP /// </summary> public class Class1 { private string strgetIP; public Class1() { // netIP(); getIP(); }
public string renetIP() {return netIP();}//返回网络IP
public string regetIP() {return strgetIP;}//返回内网IP
static string netIP() { Uri uri = new Uri("http://www.ikaka.com/ip/index.asp");//查本机网络IP的网页 HttpWebRequest req = (HttpWebRequest)WebRequest.Create(uri); req.Method = "POST"; req.ContentType = "application/x-www-form-urlencoded"; req.ContentLength = 0; req.CookieContainer = new CookieContainer(); req.GetRequestStream().Write(new byte [0], 0, 0); HttpWebResponse res = (HttpWebResponse)(req.GetResponse()); StreamReader rs = new StreamReader(res.GetResponseStream(), Encoding.GetEncoding("GB18030")); string s = rs.ReadToEnd(); rs.Close(); req.Abort(); res.Close(); Match m = Regex.Match(s, @"IP:\[(?<IP>[0-9\.]*)\]"); if (m.Success) return m.Groups["IP"].Value; string strnetIP= string.Empty; return strnetIP; }
public string getIP()//注意与static 的区别 { System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;//获取本机内网IP
strgetIP = addressList[0].ToString(); return strgetIP; }
}
