The ToArray<TSource>(IEnumerable<TSource>) method forces immediate query evaluation and returns an array that contains the query results. You can append this method to your query in order to obtain a cached copy of the query results.
ToList<TSource> has similar behavior but returns a List<T> instead of an array.
