Nhibernate QueryOver Orderby

问题

I'm trying to decouple the orderby on a queryover call and this doesn't compile

protected static void AddOrder<T>(IQueryOver<T, T> criteria, Expression<Func<object>> expression )
{
  criteria.OrderBy(expression).Asc;
}

I'm guessing there is a way to do this, somehow bringing in the asc into the linq expression? Thanks for the help!

回答1:

That's not how IQueryOver works... to make it compile, you'd have to do the following:

protected static IQueryOver<T, T> AddOrder<T>(IQueryOver<T, T> criteria,
                                              Expression<Func<object>> expression)
{
    return criteria.OrderBy(expression).Asc;
}

Which makes little sense, as it's just a dumb wrapper for OrderBy.
