asp.net 获取客户端IP与mac

2010-05-25 11:17 561 查看

以下为引用的内容：
private string GetClientIP()
{
string result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (null == result || result == String.Empty)
{
result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
}

if (null == result || result == String.Empty)
{
result = HttpContext.Current.Request.UserHostAddress;
}
return result;
}

获取MAC地址:

以下为引用的内容：
DllImport("Iphlpapi.dll")]
private static extern int SendARP(Int32 dest,Int32 host,ref Int64 mac,ref Int32 length);
[DllImport("Ws2_32.dll")]
private static extern Int32 inet_addr(string ip);

private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
try
{
string userip=Request.UserHostAddress;
string strClientIP = Request.UserHostAddress.ToString().Trim();
Int32 ldest = inet_addr(strClientIP); //目的地的ip
Int32 lhost = inet_addr(""); //本地服务器的ip
Int64 macinfo = new Int64();
Int32 len = 6;
int res = SendARP(ldest,0, ref macinfo, ref len);
string mac_src=macinfo.ToString("X");
if(mac_src == "0")
{
if(userip=="127.0.0.1")
Response.Write ("正在访问Localhost!");
else
Response.Write ("欢迎来自IP为" + userip + "的朋友！" + "
");
return;
}

while(mac_src.Length<12)
{
mac_src = mac_src.Insert(0,"0");
}

string mac_dest="";

for(int i=0;i<11;i++)
{
if (0 == (i % 2))
{
if ( i == 10 )
{
mac_dest = mac_dest.Insert(0,mac_src.Substring(i,2));
}
else
{
mac_dest ="-" + mac_dest.Insert(0,mac_src.Substring(i,2));
}
}
}

//方法二
using System.Text.RegularExpressions;
using System.Diagnostics;
public class test
{
public test
{}
public static string GetCustomerMac(string IP) //para IP is the client's IP
{
string dirResults="";
ProcessStartInfo psi = new ProcessStartInfo();
Process proc = new Process();
psi.FileName = "nbtstat";
psi.RedirectStandardInput = false;
psi.RedirectStandardOutput = true;
psi.Arguments = "-A " + IP;
psi.UseShellExecute = false;
proc = Process.Start(psi);
dirResults = proc.StandardOutput.ReadToEnd();
proc.WaitForExit();
dirResults=dirResults.Replace("/r","").Replace("/n","").Replace("/t","");

Regex reg=new Regex("Mac[ ]{0,}Address[ ]{0,}=[ ]{0,}(?((.)*?)) __MAC",RegexOptions.IgnoreCase|RegexOptions.Compiled);
Match mc=reg.Match(dirResults+"__MAC");

if(mc.Success)
{
return mc.Groups["key"].Value;
}
else
{
reg=new Regex("Host not found",RegexOptions.IgnoreCase|RegexOptions.Compiled);
mc=reg.Match(dirResults);
if(mc.Success)
{
return "Host not found!";
}
else
{
return "";
}
}
}
}

这种方法有些地方得好好摸索，不然看不懂的

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：

以下为引用的内容：
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：

以下为引用的内容：
using System.Net;

TextIP.Text=Page.Request.UserHostAddress;
