Nhibernate QueryOver Orderby [英] Nhibernate QueryOver Orderby

问题描述

我正在尝试在 queryover 调用中解耦 orderby，但这无法编译

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;
}

我猜有一种方法可以做到这一点，以某种方式将 asc 引入 linq 表达式?感谢您的帮助！

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

推荐答案

这不是 IQueryOver 的工作方式...要使其编译，您必须执行以下操作:

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;
}

这没什么意义，因为它只是 OrderBy 的一个愚蠢的包装器.

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