ASP.NET获取IP与MAC[usingC#]


获取服务器的IP地址方法以DNS法较为简单实用,如下:
using System.Net;
private void ButtonIP_Click(object sender, System.EventArgs e)
{
System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;
if ( addressList.Length>1)
{TextLIP.Text = addressList[0].ToString();
TextSIP.Text = addressList[1].ToString();
}
else
{
TextLIP.Text = addressList[0].ToString();
TextSIP.Text = "没有可用的连接";
}
}
获取服务器的IP地址与MAC地址另一方法如下:
using System.Management;
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();
TextMAC.Text = stringMAC.ToString();
string[] IPAddresses = (string[]) MO["IPAddress"];
if(IPAddresses.Length > 0)
stringIP = IPAddresses[0];
TextIP.Text = stringIP.ToString();
}
}
获取客户端本机的IP地址相当简易,方法如下:
using System.Net;
TextIP.Text=Page.Request.UserHostAddress;
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
{
///
/// Class1 的摘要说明。
/// 获取本机上网IP和内网IP
///
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:/[(?[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;
}
}
}
