       1、获取当前系统麦克风音量       

 

private int GetCurrentMicVolume()
{
    int volume = 0;
    var enumerator = new MMDeviceEnumerator();

    //获取音频输入设备
    IEnumerable captureDevices = enumerator.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.Active).ToArray();
    if (captureDevices.Count() > 0)
    {
        MMDevice mMDevice = captureDevices.ToList()[0];
        volume = (int)(mMDevice.AudioEndpointVolume.MasterVolumeLevelScalar*100);
    }
    return volume;
 }

     2、设置当前系统麦克风音量 volume 取值 0-100

       

private void SetCurrentMicVolume(int volume)
{
   var enumerator = new MMDeviceEnumerator();
   IEnumerable captureDevices = enumerator.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.Active).ToArray();
   if (captureDevices.Count() > 0)
   {
      MMDevice mMDevice = captureDevices.ToList()[0];
      mMDevice.AudioEndpointVolume.MasterVolumeLevelScalar = volume/100.0f;
   }
}
