使用NAudio，您可以执行以下操作：

using NAudio.CoreAudioApi;
.....
//  download NAudio.dll from https://github.com/naudio/NAudio/releases
//  and add it as Reference to the project

var devEnum = new MMDeviceEnumerator();
var defaultDevice = devEnum.GetDefaultAudioEndpoint(DataFlow.Render, Role.Multimedia);
var volume = defaultDevice.AudioEndpointVolume;
float leftVolumePercent = volume.Channels[0].VolumeLevelScalar * 100;
float rightVolumePercent = volume.Channels[1].VolumeLevelScalar * 100;
float masterVolumePercent = volume.MasterVolumeLevelScalar * 100;

此article演示了如何在没有外部框架的情况下实现这些目标。
