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 voidButtonIP_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;

stringstringMAC= "";
stringstringIP= "";
ManagementClassMC= new ManagementClass "Win32_NetworkAdapterConfiguration");
ManagementObjectCollectionMOC=MC.GetInstances();

foreach(ManagementObjectMOinMOC)
{
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
