The following types may not be used as proxies:
Entitys.login: method get_Upwd should be virtual
Entitys.login: method get_id should be virtual
Entitys.login: method get_Uname should be virtual
Entitys.login: method set_Uname should be virtual
Entitys.login: method get_LastTime should be virtual
Entitys.login: method set_Upwd should be virtual
Entitys.login: method set_id should be virtual
Entitys.login: method set_LastTime should be virtual

引起问题的原因:

NHibernate 1.2 默认为类启用了延迟加载功能

解决方法：

方法1.在映射文件 class 标签中添加 Lazy="false" 属性

例: lazy="false">

方法2.为每个实体类的属性成员 添加 “ virtual ” 修饰符；

例:

public virtual int id
{
get { return m_id; }
set { m_id = value; }
}
