这段代码可以将点分隔的ip地址转换成长整形数字，非常实用
public static long ConvertIPToLong(string ipAddress)
{
// code from http://www.75271.com
System.Net.IPAddress ip;
if (System.Net.IPAddress.TryParse(ipAddress, out ip))
{
byte[] bytes = ip.GetAddressBytes();
return (long)
(
16777216 * (long)bytes[0] +
65536 * (long)bytes[1] +
256 * (long)bytes[2] +
(long)bytes[3]
)
;
}
else
return 0;
}
