c# - Windows Phone 8.1 access file in Documents folder -

i'm new windows phone development, , not using silverlight or wpf. copy file "links.txt" windows phone folder @ "\documents\" , want access , content in file, i'm getting access denied error. click on package.appxmanifest file select "capabilities" tab, don't see "documents library access" me check it. matter fact don't see "... library access" showing. below code:

string filename = "\\documents\\links.txt"; string parentpath = applicationdata.current.localfolder.path; string filepath = path.combine(parentpath, filename); storagefile file = await storagefile.getfilefrompathasync(filepath); 

any suggestion how can read file? thanks.

updates:

it seems code above not work, when using code below , change folder "music" instead of "documents" check capabilities "musiclibrary", it's working.

 var folder = knownfolders.musiclibrary;  var file = await folder.getfileasync("links.txt");  var read = await fileio.readtextasync(file); 

thanks!
