//得到本机内网IP

string s = "";//定义一个变量，用来记录IP地址
System.Net.IPAddress[] addressList = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName()).AddressList;//获取IP地址列表
for (int i = 0; i < addressList.Length; i++)//遍历IP地址列表
{
    s += addressList[i].ToString() + "\n";//获得遍历到的IP地址
}
//s就是本机内网ip

获取外网IP一定要借助WEB页面吗。。就没有不访问WEB的方法？

用的是访问ip138，然后抓取内容分析的原理啊，也不错，呵呵
