如何使用C＃中的代码更改网络设置（IP地址，DNS，WINS，主机名）

我正在为要用作其他计算机备份的计算机开发向导。替换现有计算机时，需要设置其IP地址，DNS，WINS和主机名以匹配要替换的计算机。

.net（C＃）中是否有一个库可以让我以编程方式进行此操作？

有多个NIC，每个NIC需要单独设置。

谢谢TimothyP的示例。它使我朝正确的方向前进，快速的回复真是棒极了。

谢谢balexandre。您的代码是完美的。我很着急，已经修改了示例TimothyP链接到的示例，但是我希望早点编写您的代码。

我还开发了使用类似技术更改计算机名称的例程。我会在以后发布它，因此，如果您想知道更新的信息，请订阅此RSS提要。经过一番清理，我可能会在今天晚些时候或星期一起来。
