c# - 如何获取媒体设备信息？

Question

我正在使用MediaDevicesNuGet 包来识别连接到计算机的所有媒体设备。我不确定我如何获得MediaStorageInfo，例如它可以容纳多少空间或有多少可用空间。

我的代码片段：

var mediadevices = mediadevice.GetDevices();
MediaStorageInfo info = new MediaStorageInfo();
foreach (var device in mediadevices)
{
    ulong cap = info.Capacity
    ulong freespace = info.FreespaceInObjects;   
}

手册建议：

var devicess = MediaDevice.GetDevices();
using (var device = devicess.First(d => d.FriendlyName == "My Cell Phone"))
{
    device.Connect();

    // get list of available storages (SD-Card, Internal Flash, ...)
    var objects = device.FunctionalObjects(FunctionalCategory.Storage);
    MediaStorageInfo infoss = GetStorageInfo(objects.First());
    ulong size = infoss.FreeSpaceInBytes;

    device.Disconnect();
}

似乎丢失了GetStorageInfo，因为错误指出无法解决并且当前联系人中不存在。我不确定如何将我的传递MediaDevice给MediaStorageInfo. 任何建议都有帮助。谢谢！

只是改变：

GetStorageInfo(objects.First());

至

device.GetStorageInfo(objects.First())

它应该看起来像这样：

var devicess = MediaDevice.GetDevices();
using (var device = devicess.First(d => d.FriendlyName == "My Cell Phone"))
{
    device.Connect();

    // get list of available storages (SD-Card, Internal Flash, ...)
    var objects = device.FunctionalObjects(FunctionalCategory.Storage);
    MediaStorageInfo infoss = device.GetStorageInfo(objects.First());
    ulong size = infoss.FreeSpaceInBytes;

   device.Disconnect();
}
