运行结果：

 

主要使用了四种方式来获取:

一、C#直接调用DirectX来获取麦克风名称

public static List<string> GetAudioDevicesList()
       {
           var audioDevices = new CaptureDevicesCollection();
           var deviceNames = new List<string>();
           for (int i = 0; i < audioDevices.Count; i++)
           {
               var guid = (audioDevices[i]).DriverGuid;
               if (guid == Guid.Empty)
               {
                   continue;
               }
               deviceNames.Add(audioDevices[i].Description);
           }
           return deviceNames;
       }

二、使用NAudio来获取
