c# - TrySetWallpaperImageAsync always returns false even though I'm using Application LocalFolder -


the trywallpaperimageasync method returns false , not set wallpaper. if @ question: trysetwallpaperimageasync() returns false, see fix relocating image application's localfolder. doing here, reason wallpaper still not being changed. cause method fail?

string name = "wallpaper.jpg"; var file = await storagefile.getfilefrompathasync($"{applicationdata.current.localfolder.path}\\{name}"); var success = await setwallpaperasync(file);  async task<bool> setwallpaperasync(storagefile fileitem) {     bool success = false;     if (userprofilepersonalizationsettings.issupported())     {         userprofilepersonalizationsettings profilesettings = userprofilepersonalizationsettings.current;         success = await profilesettings.trysetlockscreenimageasync(fileitem);     }     return success; }

there documented limitation api when dealing duplicate filenames.

if file trying set wallpaper has same name current wallpaper, system ignore request , no-op operation (returning false).

you should use unique filename when setting wallpaper ensure gets set correctly.
