嵌入式语句的流畅NHibernate错误

Question

这是我的代码;

    public ActionResult Login(User user, string returnUrl)
    {
        using (ISession session = FluentNHibernateConnect.OpenSession())

        var users = session.QueryOver<User>()
        .Where(user.Nick == "asd")
        .And(user.Password == "1234")
        .List();

    }

问题是什么。 var和.where（user.nick ==“asd”）红线？

库;

• System.Web.Mvc;
• 的System.Web;

Answer 1

where方法采用表达式：

var users = session.QueryOver<User>()
    .Where(user => user.Nick == "asd")
    .And(user => user.Password == "1234")
    .List();
