以编程方式启用/禁用连接

Question

在Windows 7上,我可以通过"网络连接管理器"面板启用和禁用连接(在系统设置中).

如何在C#中以编程方式执行此操作？谢谢

您可以通过利用WMI和Win32_NetworkAdapter WMI类在C#中实现此目的.Win32_NetworkAdapter类具有可在选定网络接口上执行的启用和禁用方法.

可以在此处找到使用示例:

简而言之,执行此操作的步骤是:

1. 从VS命令提示符生成类的包装器

   mgmtclassgen Win32_NetworkAdapter /L CS -p NetworkAdapter.cs

2. 单步执行适配器:

   SelectQuery query = new SelectQuery("Win32_NetworkAdapter", "NetConnectionStatus=2");
   ManagementObjectSearcher search = new ManagementObjectSearcher(query);
   foreach(ManagementObject result in search.Get()) {
    NetworkAdapter adapter = new NetworkAdapter(result);
    // Identify the adapter you wish to disable here. 
    // In particular, check the AdapterType and 
    // Description properties.
    // Here, we're selecting the LAN adapters.
    if (adapter.AdapterType.Contains("Ethernet 802.3")) {
       adapter.Disable();
    }
   }
