asp获取手机mac_asp.net 获取客户端IP与mac

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";

}

}
