编程方式启用/禁用连接 [英] Programmatically Enable / Disable Connection

问题描述

在Windows 7上我可以启用和通过网络连接管理器面板（系统设置）禁用连接。

on Windows 7 I can enable and disable connections via the Network Connections Manager panel (in system settings).

如何在C＃中做到这一点编程？谢谢

How can I do this programmatically in C#? Thanks

推荐答案

您可以在C＃中通过利用WMI和Win32_NetworkAdapter这WMI类实现这一目标。 。Win32_NetworkAdapter类有启用并可以选择的网络接口上执行禁用方法

You can achieve this in C# by leveraging WMI and the Win32_NetworkAdapter WMI class. The Win32_NetworkAdapter class has Enable and Disable methods which can be executed on a selected network interface.

用法的例子可以在这里找到：

简单地说，步骤要做到这一点是：

Briefly, steps to do this are:

1. 生成从VS类的包装命令提示符

1. Generate a wrapper for the class from VS command prompt

mgmtclassgen Win32_NetworkAdapter /L CS -p NetworkAdapter.cs

通过适配器步进：

Stepping through the adapters:

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();
 }
}
