C# NHibernate在匹配DateTime对象时遇到问题

我在ASP.NET MVC中有这个简单的操作

    [HttpGet]
    public IEnumerable<EventDTO> Get(int bed, DateTime date)
    {
        using (var session = DBSessionFactory.OpenSession())
        {
            return session.Query<Event>()
                .Where(e =>
                    e.Bed.Id == bed
                    && e.Date == date)
                .ToList()
                .Select(x => Mapper.Map<EventDTO>(x))
                .ToList();
        }
    }

关于DateTime/Time/DateTimeOffset/Date数据类型，我总是明确地告诉映射中的预期类型，因为从缺少日期类型的底层属性类型.Net推断时可能会有一些歧义

通常对于db DateTime，我在属性映射上指定NHibernate类型的时间戳。请参阅可用类型列表。根据您的用例，有许多可能的类型可供选择。

您也可以指定一些非NHibernate类型，如前所述。

这是从哪里来的输入字符串“10:00:00”的格式不正确。。。。。在我看来，这不太像NH，但mapperI认为Keith可能是对的，同时你能为你的事件类发布你的流畅的map/XML映射吗？添加事件类定义可能也会有帮助。异常调用堆栈将帮助检查Keith是否正确。@sh1rts我添加了事件类。看一看。@Frédéric我添加了堆栈跟踪。看一看，DB中引起问题的列不是DATETIME，而是一个时间字段。使用.CustomTypeTimeAsTimeSpan；解决了这个问题。非常感谢。
