获取音频设备的列表，并使用C＃选择一个 [英] Get list of audio devices and select one using c#

问题描述

我在Windows中使用C＃创建基于桌面应用程序。

Hi I am creating a desktop based application in windows using C#.

我要显示所有可用的音频功放和名单;在2个不同的组合框视频设备。
从组合框中选择的任何设备将设置特定的设备作为默认的

I have to show list of all available audio & video devices in 2 different combo boxes. Selecting any device from combo box will set that particular device as the default one

我使用WMI。

code来获得可用的音频设备列表：

Code to get list of available audio devices:

ManagementObjectSearcher mo = 
      new ManagementObjectSearcher("select * from Win32_SoundDevice");

foreach (ManagementObject soundDevice in mo.Get())
{
     String deviceId = soundDevice.GetPropertyValue("DeviceId").ToString();
     String name  = soundDevice.GetPropertyValue("Name").ToString();

  //saving the name  and device id in array
} 

如果我尝试设置设备是这样的：

if i try to set the device like this:

 using (RegistryKey audioDeviceKey = 
Registry.LocalMachine.OpenSubKey(audioDevicesReg
   + @"\" + audioDeviceList.SelectedText.ToString(), true)){}

我得到异常：

System.Security.SecurityException occurred in mscorlib.dll

现在我有几个问题：

1) How to set the selected device as the default audio device?
2) The array contains device name as : "High Definition audio device" 
even when I have attached a headset.
3) I want the list as speaker,headset etc...How to get that?

任何人可以点我在正确的方向？

can anybody point me in the right direction?
