从共享打开文件，传输后台传输

Question

我创建了一个从私人服务器下载pdf文件的应用程序，并将其存储在“shared / transfers”目录中。关键是：pdf文件是完全隐藏的，我看不到我已下载的pdf，adobe reader app也无法识别它

Answer 1

我刚用默认启动器打开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.

我认为这符合您的要求。
