ASP.net得到服务器的IP地址

[SKY徐]

我的服务器在局域网中, 我想要得到服务器外网的IP地址,请帮助. 谢谢!

如果是通过ip138得到再输出, 就不用说了.
如果是得到是局域网的IP,如:192.168.1.* 这不用说了,
请求帮助, 谢谢!!!!!!

是不是代理服务器？

string userIp = Request.UserHostAddress.ToString();
string ipa=Request .ServerVariables ["REMOTE_ADDR"];
this.Label1.Text = userIp+"a"+ipa;
//主机ip
string hostip = Dns.GetHostName();
IPAddress[] ips;
ips = Dns.GetHostAddresses(hostip);
foreach (IPAddress ip in ips)
{
this.TextBox1.Text = ip.ToString ();

不访问外网服务器，你得不到。因为到底通过了多少个路由器、Proxy，不确定。

你必须访问外网服务器，然后通过返回结果带回来IP。这跟访问IP138是一个意思。

[以专业开发人员为伍]

这就好象是说，想知道自己的人品，那么先看看别人怎么说....！

你的服务器就算是能访问最近的路由器，也不一定能从这个路由器上知道外网地址啊。因为从一个局域网（比如很多城域网宽带网络）到互联网的出口在哪里，不是靠访问本机或者你办公室里的路由器可以决定的。
