c# - UnAuthorizedAccessException on StorageFolder.GetFolderFromPathAsync while having access through FilePicker -


i try read files network location. keep getting unauthorizedaccessexception.

i pick storagefolder through storagefolder.getfolderfrompathasync listing files throws exception.

when pick same folder through folderpicker works.

so tried pinpointing problem code:

folderpicker picker = new folderpicker(); picker.filetypefilter.add("*");  storagefolder pickedfolder = await picker.picksinglefolderasync(); if (pickedfolder != null) {     var pickedfolderlist = await pickedfolder.getfilesasync();     var count = pickedfolderlist.count;     if (count > 0)     {         storagefolder folder = await storagefolder.getfolderfrompathasync(pickedfolder.path);         var pathfolderlist = await folder.getfilesasync(); //exception         if (pathfolderlist.count == count)         {              processfolder(folder);         }     } }

the exception thrown @ marked line variable pathfolderlist set. while had listed same folder few lines above.

i have set these capabilities:

<capabilities>   <capability name="internetclient" />   <capability name="privatenetworkclientserver"/>   <uap:capability name="enterpriseauthentication"/>   <uap:capability name="removablestorage"/> </capabilities>

what missing?

your app doesn't have access path. permission access file handled via storagefolder returned picker.

instead of line try create new storagefolder pickedfolder

storagefolder folder = await storagefolder.getfolderfrompathasync(pickedfolder.path);

just use pickedfolder itself:

var pathfolderlist = await pickedfolder.getfilesasync(); //exception

i went in more detail in blog entry skip path: stick storagefile
