检测是否插入耳机，或不通过C＃堵塞 [英] Detect if headphones are plugged in or not via C#

问题描述

有没有比如如何检测是否插入耳机，或不通过C＃堵塞。

There is no example how to detect if headphones are plugged in or not via C#.

我想应该是一些事件......

I assume should be some event for that...

有一定道理使用WMI？

Does make sense to use WMI?

 ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\cimv2",
                                                                  "SELECT * FROM Win32_SoundDevice");

foreach (ManagementObject queryObj in searcher.Get())
{
    Console.WriteLine("-----------------------------------");
    Console.WriteLine("Win32_SoundDevice instance");
    Console.WriteLine("-----------------------------------");
    Console.WriteLine("StatusInfo: {0}", queryObj["StatusInfo"]);
}

会有人如此高兴规定的？

Would anyone be so pleased to provide it?

感谢您！

推荐答案

检测这种变化是可以通过使用的 IMMDeviceEnumerator :: RegisterEndpointNotificationCallback 方法。

Detecting changes of this kind is possible by using the IMMDeviceEnumerator::RegisterEndpointNotificationCallback method.

当你要处理这在C＃中，您将需要它已经被阿科什Mattiassich实现的托管包装。你可以在这里找到一个thourough例如：托管包装周围MMAudioDeviceApi

As you want to handle this in C# you will need a managed wrapper which has already been implemented by Akos Mattiassich. You can find a thourough example here: Managed Wrapper around MMAudioDeviceApi

他说：

该程序可以在选定的设备和它玩测试声音自动更新上的变化如表。通过控制面板或在物理上插入新的设备的情况下。

The program can play test sound on selected devices and it updates the list automatically on changes eg. through the control panel or in case of plugging new device physically.
