获得从Dns.GetHostEntry IPv4地址（） [英] Get IPv4 addresses from Dns.GetHostEntry()

问题描述

我有一些在这里code上的IPv4机器的伟大工程，但我们构建服务器（在IPv6）的失败。简而言之：

I've got some code here that works great on IPv4 machines, but on our build server (an IPv6) it fails. In a nutshell:

IPHostEntry ipHostEntry = Dns.GetHostEntry(string.Empty);

该文档GetHostEntry说，传递的String.Empty将让你的本地主机的IPv4地址。这就是我想要的。问题是，它的返回字符串:: 1：我们的IPv6的机器，我相信这是IPv6的地址

The documentation for GetHostEntry says that passing in string.Empty will get you the IPv4 address of the localhost. This is what I want. The problem is that it's returning the string "::1:" on our IPv6 machine, which I believe is the IPv6 address.

这是任何其他的IPv4机执行ping本机提供了一个很好的IPv4地址...和做一个平-4计算机名从本身提供了正确的IPv4地址....但定期查验其从本身赋予:: 1：

Pinging the machine from any other IPv4 machine gives a good IPv4 address... and doing a "ping -4 machinename" from itself gives the correct IPv4 address.... but pinging it regularly from itself gives "::1:".

我怎样才能获得IPv4的这台机器，从本身？

How can I get the IPv4 for this machine, from itself?

推荐答案

你看<一href="http://msdn.microsoft.com/en-us/library/system.net.iphostentry.addresslist%28VS.80%29.aspx">all地址的在返回，丢弃的<一的那些href="http://msdn.microsoft.com/en-us/library/system.net.ipaddress.addressfamily%28VS.80%29.aspx">family InterNetworkV6 ，只保留IPv4的那些？

Have you looked at all the addresses in the return, discard the ones of family InterNetworkV6 and retain only the IPv4 ones?
