推荐答案

这里是一种检索所有声音设备的方法:

Here is a way to retrieve all sound devices:

ManagementObjectSearcher objSearcher = new ManagementObjectSearcher(
           "SELECT * FROM Win32_SoundDevice");

ManagementObjectCollection objCollection = objSearcher.Get();

foreach (ManagementObject obj in objCollection)
{
  foreach (PropertyData property in obj.Properties)
  {
    Console.Out.WriteLine(String.Format("{0}:{1}", property.Name, property.Value));
  }
}
