Question

我如何获得可用的声音设备列表？我的意思是那个形象。

enter image description here

我想在组合框中使用它。我的意思是：

麦克风
Stereo Mix
Line In
..等等..

但必须真的是因为系统根据语言本地化系统更改了设备的名称，这就是我需要的。

例如，我的语言是Microphone，名为Mikrofon，Stereo Mix =Směšovač立体声

enter image description here

我需要获得这些设备名称，没有别的

可以制作一些示例代码吗？

Answer 1

这就是我需要的......

    [DllImport("winmm.dll", SetLastError = true)]
    static extern uint waveInGetNumDevs();

    [DllImport("winmm.dll", SetLastError = true, CharSet = CharSet.Auto)]
    public static extern uint waveInGetDevCaps(uint hwo, ref WAVEOUTCAPS pwoc, uint cbwoc);

    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
    public struct WAVEOUTCAPS
    {
        public ushort wMid;
        public ushort wPid;
        public uint vDriverVersion;
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 64)]
        public string szPname;
        public uint dwFormats;
        public ushort wChannels;
        public ushort wReserved1;
        public uint dwSupport;
    }

    public static string[] GetSoundDevices()
    {
        uint devices = waveInGetNumDevs();
        string[] result = new string[devices];
        WAVEOUTCAPS caps = new WAVEOUTCAPS();
        using (StreamWriter sw = new StreamWriter("appdata/audio/name"))
        {
            for (uint i = 0; i < devices; i++)
            {
                waveInGetDevCaps(i, ref caps, (uint)Marshal.SizeOf(caps));
                result[i] = caps.szPname;
                sw.WriteLine(caps.szPname);
            }
            return result;
        }
    }

..但是每一行都缩短了，我不能全部写完。

如何修改列出整个名称的代码？

谢谢！

使用它对我有用

using NAudio.CoreAudioApi;

MMDeviceEnumerator names = new MMDeviceEnumerator();
var devices = names.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.Active);            
foreach (var device in devices)
    MessageBox.Show(device.friendlyName);

以下代码可帮助您获取音频设备列表

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));
        }
    }

现在，您可以使用for-each枚举列表。

输出将是这样的，

从列表中获取标题值。这是简单的文本解析问题;）

C＃中的捕获设备列表（例如麦克风，立体声混音......）
