Windows IoT Raspberry Pi 3 C# 保存设备设置

Question

我想知道如何为我选择的 USB 设备保存我的用户配置。每当我重新启动设备时，它将按照我之前选择的方式加载。 是保存在本地还是usb存储？

此应用说明Store and retrieve settings and other app data 是否适用于提到的应用数据类型适用于 USB 适配器？

更新：

当我从列表框中选择 USB 适配器时，我相应地设置了相应的选定设备。

        private void audioCaptureList_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            recordPlayer.AudioDevice = captureDeviceList[audioCaptureList.SelectedIndex];
        }

        private void audioRenderList_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            mediaPlayer.AudioDevice = renderDeviceList[audioRenderList.SelectedIndex];

        }

您的设置可以保存为Local app data。即使您重新启动设备，这些数据也不会改变。但是注意：the lifetime of the app data is tied to the lifetime of the app. If the app is removed, all of the app data will be lost as a consequence。

您可以像这样存储和检索本地应用数据：

    Windows.Storage.ApplicationDataContainer localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;

    private void StoreButton_Click(object sender, RoutedEventArgs e)
    {
        var selection = ConnectDevices.SelectedItems;
        var entry = (DeviceListEntry)selection[0];
        var device = entry.DeviceInformation;

        localSettings.Values["SelectedUsbDeviceId"] =  device.Id;
        localSettings.Values["SelectedUsbDeviceName"] = device.Name;
    }

    private void RetrieveButton_Click(object sender, RoutedEventArgs e)
    {
        Object deviceId = localSettings.Values["SelectedUsbDeviceId"];
        Object deviceName = localSettings.Values["SelectedUsbDeviceName"];
    }
