c# - 如何使用 C# 检测连接到我的机器的摄像头

Question

我能够知道连接到我的 PC 的声音设备和 USB 设备，但无法找到连接到我的机器的相机。使用下面的代码获取声音设备

Console.WriteLine("Win32 SoundDevices\r\n===============================");
            ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * from Win32_SoundDevice");
            foreach (ManagementObject soundDevice in searcher.Get())
            {
                //Console.WriteLine("Device found: {0}\n", soundDevice.ToString());
                Console.WriteLine("Device found: {0}\n", soundDevice.GetPropertyValue("ProductName"));
            }
            Console.WriteLine("Search complete.");

我编写了一个对我来说效果很好的解决方案。该方法在我的笔记本电脑上找到了两个 USB 摄像头和一个集成摄像头。

private static async Task ListAllCamerasAsync()
{
    ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM win32_PNPEntity WHERE PnPClass='Camera'");
    var collection = await Task.Run(() => { return searcher.Get(); });
    var cameraIndex = 0;
    foreach (ManagementObject cameraDevice in collection)
    {
        Console.WriteLine($"Camera {cameraIndex}: {cameraDevice["Name"]}");
        cameraIndex++;
    }
}
