ASP.NET获取IP与MAC地址的方法

获取服务器的IP地址方法以DNS法较为简单实用，如下：

private void ButtonIP_Click(object sender, System.EventArgs e)

{

Syste m.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;
