帮我看下监视封包的程序，为什么获取的封包有重复？

[pyz8000]

网上找到了RawSocket类，"C#下的Raw Socket编程实现网络封包监视"的代码
我在百度上输入“asdlkfjaslkdhfgasdf" 然后用程序监视“asdlkfjaslkdhfgasdf”
结果会有很多"asdlkfjaslkdhfgasdf"的数据包，
抓到的封包总有重复，为什么？
应该只有一个“asdlkfjaslkdhfgasdf”才对，最多二个，一个是我发送，另一个是接收，
可我抓到了十几个
我用commview软件就只有一个数据包，请高手帮忙

private void btRun_Click(object sender, System.EventArgs e)
{
	string sIp = Dns.GetHostByName(Dns.GetHostName()).AddressList[0].ToString();
	RawSocket rs = new RawSocket();
	rs.CreateAndBindSocket(sIp);
	rs.PacketArrival += new RawSocket.PacketArrivedEventHandler(GoSJB);
	rs.Run();
}
private void GoSJB(Object sender, RawSocket.PacketArrivedEventArgs e)
{
	string s="";
	//s = Encoding.GetEncoding("gb2312").GetString(e.ReceiveBuffer);
	s = Encoding.Default.GetString(e.ReceiveBuffer);
	if (s.Replace(tbFindText.Text, "").Length != s.Length)
	{
		s = s.Replace("\0", "");
		tbText.Text += s + "----------------------"+ e.DestinationAddress + ":"+ e.DestinationPort + e.OriginationAddress + ":"+ e.OriginationPort +"-------------------------------";
		StringBuilder sb = new StringBuilder();
		for (int i = 0; i < e.PacketLength; i++)
		{
			s = Convert.ToString(e.ReceiveBuffer[i], 16);
			if (s.Length==1)
				s = "0"+s;
			sb.Append(s + " ");
		}
		tb16.Text += sb.ToString().ToUpper() + "------------------------" + e.DestinationAddress + ":" + e.DestinationPort + e.OriginationAddress + ":" + e.OriginationPort + "-----------------------------";
		tbFBS.Text=(int.Parse(tbFBS.Text)+1).ToString();
	}
}

lz,RawSocket 类能共享下吗,我找了几个好象都不全

好啊，等我改对了，我在发源码让大家下载啊
