UWP如何获得StorageDevice的可用空间和容量?

问题描述

在我的UWP应用中，我使用此构造来获取所有StorageDevices的列表:

in my UWP app I use this construction to get list of all StorageDevices:

List<StorageFolder> list = new List<StorageFolder>();
var selector = Windows.Devices.Portable.StorageDevice.GetDeviceSelector();

var devices = await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(selector);

foreach (Windows.Devices.Enumeration.DeviceInformation device in devices)
    {
        // Get device root folder
        StorageFolder rootFolder = Windows.Devices.Portable.StorageDevice.FromId(device.Id);
        list.Add(rootFolder);
    }

RemovableItems.DataContext = new RemovableStorageViewModel(list);

如何获得此设备的自由空间和容量?我尝试从文件夹道具 rootFolder.Properties.RetrievePropertiesAsync(new List< string>())中获取它，但是缺少该道具.

推荐答案

我尝试做同样的事情没有成功.Microsoft出于某些原因省略了这些属性.希望下一个SDK更新能够解决这个问题.

I've tried without success to do the same thing. Microsoft has omitted those properties for some reason. Hoping that the next SDK update will address this.
