由网友(国际美男)分享简介：我有以下的code：Dim ipAdd As IPAddress = Dns.GetHostEntry(strHostname).AddressList(0)Dim strIP As String = ipAdd.ToString()当我转换为字符串，而不是IPv4地址192.168.1.0一样或类似的，我得到IP...

我有以下的code：

Dim ipAdd As IPAddress = Dns.GetHostEntry(strHostname).AddressList(0)
Dim strIP As String = ipAdd.ToString()

当我转换为字符串，而不是IPv4地址192.168.1.0一样或类似的，我得到IPv6版本：FD80 :: 5dbe：5d89：E51B：D313地址

When I convert to String instead of an IPv4 address like 192.168.1.0 or similar I get the IPv6 version: fd80::5dbe:5d89:e51b:d313 address.

有没有一种方法可以让我返回从ip地址类型IPv4地址？

Is there a way I can return the IPv4 address from IPAddress type?

感谢

推荐答案

而不是无条件地采取AddressList中的第一个元素，你可以采取的第一个IPv4地址：

Instead of unconditionally taking the first element of the AddressList, you could take the first IPv4 address:

var address = Dns.GetHostEntry(strHostname)
                 .AddressList
                 .First(ip => ip.AddressFamily == AddressFamily.InterNetwork);
