推荐答案

什么是MMDevice： https://wiki.videolan.org/Documentation:Modules/mmdevice/ [ ^ ]



重要性： Vista Core Audio API Master Volume Control [ ^ ]



如何使用它： http://msdn.microsoft.com/en-us/library/windows/desktop/dd316556(v = vs.85）.aspx [ ^ ]

what is MMDevice :https://wiki.videolan.org/Documentation:Modules/mmdevice/[^]

Importance of it : Vista Core Audio API Master Volume Control[^]

How to Use it :http://msdn.microsoft.com/en-us/library/windows/desktop/dd316556(v=vs.85).aspx[^]

问题是关于C＃。

MMDeviceEnumerator的示例用法可以在 http://naudio.codeplex.com上的C＃开源项目NAudio中找到。 / 使用最新来源 NAUDIO来源 [ ^ ]。

一旦你引用项目

The question was regarding C#.
An example usage of MMDeviceEnumerator can be found in the C# open source project NAudio at http://naudio.codeplex.com/ with the latest source at NAUDIO Source[^].
Once you reference the project with

#using NAudio.CoreAudioAPI

然后您可以使用以下内容枚举您的音频设备...

then you can enumerate your audio devices with the following...

var deviceEnum = new MMDeviceEnumerator();
var devices = deviceEnum.EnumerateAudioEndPoints(DataFlow.All, DeviceState.Active).ToList();

MMDeviceEnumerator定义如下：

The MMDeviceEnumerator is defined as follows:

/// <summary>
/// implements IMMDeviceEnumerator
/// </summary>
[ComImport, Guid("BCDE0395-E52F-467C-8E3D-C4579291692E")]
class MMDeviceEnumeratorComObject
{
}

如果你在注册表中查找GUID引用，它将在文件MMDevAPI.dll中实现

and if you look up the GUID reference in the registry, it is implemented in the file MMDevAPI.dll

如上所述，但CoreAudioAPI中的API不是全部在首都



使用NAudio.CoreAudioApi;

As above but the API in CoreAudioAPI is not all in capitals

using NAudio.CoreAudioApi;
