c# - 如何在 Windows 10 和 > .net 4.5 中用 c# 枚举音频输入设备？

Question

如何获取 Windows 系统上已安装音频输入设备的列表？ 操作系统:Windows(10) 框架:.Net >= 4.5 语言:c#

我已经尝试过使用这个:

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

 ManagementObjectCollection objCollection = objSearcher.Get();

但这给了我所有设备的列表，我只需要输入设备列表

您可以使用 DirectSoundCaptureEnumerate :

using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;
public class DirectSoundDevices
{
    [DllImport("dsound.dll", CharSet = CharSet.Ansi)]
    static extern void DirectSoundCaptureEnumerate(DSEnumCallback callback, IntPtr context);
    delegate bool DSEnumCallback([MarshalAs(UnmanagedType.LPStruct)] Guid guid,
        string description, string module, IntPtr lpContext);
    static bool EnumCallback(Guid guid, string description, string module, IntPtr context)
    {
        if (guid != Guid.Empty)
            captureDevices.Add(new DirectSoundDeviceInfo(guid, description, module));
        return true;
    }
    private static List<DirectSoundDeviceInfo> captureDevices;
    public static IEnumerable<DirectSoundDeviceInfo> GetCaptureDevices()
    {
        captureDevices = new List<DirectSoundDeviceInfo>();
        DirectSoundCaptureEnumerate(new DSEnumCallback(EnumCallback), IntPtr.Zero);
        return captureDevices;
    }
}
public class DirectSoundDeviceInfo
{
    public DirectSoundDeviceInfo(Guid guid, string description, string module)
    { Guid = guid; Description = description; Module = module; }
    public Guid Guid { get; }
    public string Description { get; }
    public string Module { get; }
}

您还可以使用 waveInGetDevCaps但对于设备名称，它返回设备名称的前 32 个字符。
