Question

我尝试使用C＃创建一个简单地接受网络适配器配置的工具，然后我可以重新配置它们。

我本可以准备好如何获得：

IP地址
子网掩码
默认网关
DNS主要和次要。

但是我已经坚持了一周如何设置适配器的上层细节（给定NIC适配器名称）。

伪代码：

setNIC(NIC_AdapterName, ip, submask, DGW, DNS1, DNS2)
{
    NIC_AdapterName.ip = ip;
    NIC_AdapterName.subnetmask = submask;
    .
    .
    .
    // and so on
}

使用System.Management命名空间
