请问如何编程得到本地区的域名服务器地址(DNS)?

[NowCan]

什么是本地区的域名服务器？
如果是本机设置，用Iphelp就可以。

这是以前的一点资料，我贴给你
/////////////////////////////////////////////////////////////////////////////////
通过注册表只能来读取参数！！所有对注册表的修改都需要重新引导！！
方法是通过通过WinExec("netsh -c interface ip dump >c:\interface.txt")的方式可以导出配置脚本后修改interface.txt文件后将该文件倒入：WinExec("netsh -f c:\\interface.txt").
但是你也可以查下资料看看可不可以通过netsh直接修改DNS。我只知道修改IP,GATEWAY,METRIC等没有修改过DNS :)
(注:要求OS为WIN2000)
/////////////////////////////////////////////////////////////////////////////////
Win2k中通过控制台添加一个新的DNS以后会在system32\dns下产生一个域名.dns的文件,并且在注册表中也添加了相应的键值.但是通过api添加的函数就不太清楚了.
