You could try creating a extension method something like this. (haven't tested this)

public static ITypeSearch<T> AllCategoriesMatch<T>(this ITypeSearch<T> search, IEnumerable<int> categories) where T : ICategorizable
{
      foreach (var category in categories)
      {
          search = search.Filter(p => p.Category.Match(category));
      }
            return search;
}

and in your query

_client.Search<ArticlePage>().AllCategoriesMatch(selectedCategories)
