错误如下！！

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:<class name="Entitys.login, Entitys" table="login" 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; }
      }
