 thnk you, didn't use linq.

i've done :

 

using (isolatedstoragefile isostore = isolatedstoragefile.getuserstoreforapplication())

       .
       .
       .

    using (isolatedstoragefilestream isostream = new isolatedstoragefilestream(settingfilepath, filemode.open, isostore))
	{
        isostream.position = 0;
        xmlreader xmlreader;
        xmlreader = xmlreader.create(isostream);
