如何构建一个空的DeviceInformationCollection？

using Windows.Devices.Enumeration;

DeviceInformationCollection emptyCollection = await Task.FromResult<DeviceInformationCollection>(null);

using System;
using System.Threading.Tasks;
using Windows.Devices.Enumeration;

namespace DeviceInformationCollectionExample
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // 构建一个空的DeviceInformationCollection
            DeviceInformationCollection emptyCollection = await Task.FromResult<DeviceInformationCollection>(null);

            // 添加模拟设备信息到集合中
            emptyCollection = new DeviceInformationCollection();
            emptyCollection.Add(new DeviceInformation("Device1", "Device1Id", DeviceInformationKind.Device));

            // 打印集合中的设备信息
            foreach (DeviceInformation device in emptyCollection)
            {
                Console.WriteLine($"Device Name: {device.Name}, Device Id: {device.Id}, Device Kind: {device.Kind}");
            }
        }
    }
}
