打开文件从共享，传输后台传输

Question

我创建了一个应用程序，可以从私人服务器下载pdf文件并将其存储在"shared/transfers"目录中。关键是:pdf文件是完全隐藏的，我无法看到我下载的pdf, adobe reader应用程序也无法识别它

Answer 1

我刚刚用默认启动器打开了下载的文件，试试这个

StorageFolder folder = await ApplicationData.Current.LocalFolder.GetFolderAsync("Shared");    //I'm accessing the shared folder from LocalFolder
StorageFolder subfolder = await folder.GetFolderAsync("Transfers");    //Here i'm accessing transfers folder from shared folder
StorageFile bqfile = await subfolder.GetFileAsync("Your filname");    //here accesing the file from transfers folder.
await Windows.System.Launcher.LaunchFileAsync(bqfile);    // launching the file with default launcher.
