Best way to programmatically configure network adapters in .NET
提问by TimK
I have an application written in C# that needs to be able to configure the network adapters in Windows. I have this basically working through WMI, but there are a couple of things I don't like about that solution: sometimes the settings don't seem to stick, and when the network cable is not plugged in, errors are returned from the WMI methods, so I can't tell if they really succeeded or not.
我有一个用 C# 编写的应用程序，它需要能够在 Windows 中配置网络适配器。我基本上通过 WMI 进行了这项工作，但有一些我不喜欢该解决方案的地方：有时设置似乎不固定，并且当未插入网线时，WMI 会返回错误方法，所以我不知道他们是否真的成功了。
I need to be able to configure all of the settings available through the network connections - Properties - TCP/IP screens.
我需要能够通过网络连接 - 属性 - TCP/IP 屏幕配置所有可用设置。
What's the best way to do this?

You could use Processto fire off netshcommands to set all the properties in the network dialogs.
你可以使用Process火过的netsh命令来设置在网络对话框中的所有属性。
eg: To set a static ipaddress on an adapter
例如：在适配器上设置静态 ipaddress
netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0 192.168.0.1 1
To set it to dhcp you'd use
要将其设置为 dhcp，您将使用
netsh interface ip set address "Local Area Connection" dhcp
To do it from C# would be
从 C# 中做到这一点将是
Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo("netsh", "interface ip set address \"Local Area Connection\" static 192.168.0.10 255.255.255.0 192.168.0.1 1");
p.StartInfo = psi;
p.Start();
Setting to static can take a good couple of seconds to complete so if you need to, make sure you wait for the process to exit.
设置为静态可能需要几秒钟才能完成，因此如果需要，请确保等待进程退出。

I can tell you the way the trojans do it, after having to clean up after a few of them, is to set registry keys under HKEY_LOCAL_MACHINE. The main ones they set are the DNS ones and that approach definitely sticks which can be atested to by anyone who has ever been infected and can no longer get to windowsupdate.com, mcafee.com etc.
我可以告诉你，木马的做法是在一些木马之后不得不清理之后，就是在HKEY_LOCAL_MACHINE下设置注册表项。他们设置的主要是 DNS 的，这种方法肯定会坚持下去，任何曾经被感染过并且无法再访问 windowsupdate.com、mcafee.com 等的人都可以证明这一点。

with the help of @PaulB's answers help
在@PaulB 的回答帮助下
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo("netsh", "interface ip set address " + nics[0].Name + " static 192.168." + provider_ip + "." + index + " 255.255.255.0 192.168." + provider_ip + ".1 1");
p.StartInfo = psi;
p.StartInfo.Verb = "runas";
p.Start();
