示例1: Initialize
public async Task Initialize(ICamera camera, IStorage storage)
{
this.camera = camera;
this.storage = storage;
var cacheFolder = KnownFolders.PicturesLibrary;
this.dropFolder = await cacheFolder.GetFolderAsync("securitysystem-cameradrop");
this.dropFolderWatcher = dropFolder.CreateFileQuery();
var images = await this.dropFolderWatcher.GetFilesAsync();
var orderedImages = images.OrderByDescending(x => x.DateCreated);
this.newestImage = orderedImages.FirstOrDefault();
this.dropFolderWatcher.ContentsChanged += DropFolderWatcher_ContentsChanged;
this.allJoynBusAttachment = new AllJoynBusAttachment();
this.producer = new SecuritySystemProducer(this.allJoynBusAttachment);
this.allJoynBusAttachment.AboutData.DefaultAppName = Package.Current.DisplayName;
this.allJoynBusAttachment.AboutData.DefaultDescription = Package.Current.Description;
this.allJoynBusAttachment.AboutData.DefaultManufacturer = Package.Current.Id.Publisher;
this.allJoynBusAttachment.AboutData.SoftwareVersion = Package.Current.Id.Version.ToString();
this.allJoynBusAttachment.AboutData.IsEnabled = true;
this.producer.Service = this;
this.producer.Start();
}示例2: GetFolderSize
public static async Task<double> GetFolderSize(StorageFolder folder)
{
// Query all files in the folder. Make sure to add the CommonFileQuery
// So that it goes through all sub-folders as well
var folders = folder.CreateFileQuery(CommonFileQuery.OrderByName);
// Await the query, then for each file create a new Task which gets the size
var fileSizeTasks = (await folders.GetFilesAsync()).Select(async file => (await file.GetBasicPropertiesAsync()).Size);
// Wait for all of these tasks to complete. WhenAll thankfully returns each result
// as a whole list
var sizes = await Task.WhenAll(fileSizeTasks);
// Sum all of them up. You have to convert it to a long because Sum does not accept ulong.
var folderSize = sizes.Sum(l => (long)l);
return folderSize;
}示例3: GetMediaFromFolder
private static async Task<IReadOnlyList<StorageFile>> GetMediaFromFolder(StorageFolder folder,
CommonFileQuery query)
{
