在Windows 8 App中将文件保存在Assets文件夹中

Question

I am developing an App for Windows Store. I have to save a recorded media as "file1.mp3" into the Assets folder without opening the save file prompt. I used the following code

StorageFile file = await Windows.ApplicationModel.Package.Current.InstalledLocation.CreateFileAsync(@"Assets\\file1.mp3",Windows.Storage.CreationCollisionOption.ReplaceExisting);

However the system returns an "access denied" error. The file has to be saved in the Assets directory only and I do not want to use FileSavePicker . Please Help.

Thanks

Your package folder is read-only. Use your app data folders from Windows.Storage.ApplicationData.Current instead, wherein you'll find a LocalFolder and TemporaryFolder (also RoamingFolder but an mp3 would exceed the 100KB roaming limit). Then you can use either folder's CreateFileAsync.
