[solved] Argument out of range exception on SynchronizeFolder()

Aug 9, 2012 at 4:54 PM


i try to synchronize a local folder with dropbox, but i run into a problem with an ArgumentOutOfRange exception. Dose anyone know a solution for this failure?

Two folders, one on my local disk, on in dropbox.

If the local folder contains a file, that is not available in the dropbox folder, the synchronize copys the file correct into dropbox. If a file exists only in dropbox and not in the local folder, the Synchronize() method throws an argument out of range exception. I tried to sync a HelloWorld.txt file ...


        public void SyncFolder(SaveGameFolder folder)
            ICloudDirectoryEntry root = _dropBoxStorage.GetRoot();

            bool folderExist = root.FileSystemEntryExits(folder.GameName);

            if (!folderExist)
                ICloudDirectoryEntry entry = _dropBoxStorage.GetRoot();
                _dropBoxStorage.CreateFolder(folder.GameName, entry);

            ICloudDirectoryEntry gameFolder = _dropBoxStorage.GetFolder(folder.GameName, root);
            DirectoryInfo info = new DirectoryInfo(folder.FolderPath);

            _dropBoxStorage.SynchronizeFolder(info, gameFolder, CloudStorage.SyncFolderFlags.Synchronize);

You should open an own thread for your question. Your reply dose not solve my reported problem ...

I found a solution on the sourcecode -> patches screen. The checkin 11540 solved the issue for me.
