如何分辨功能NHibernate没有映射类属性 [英] How to tell Fluent NHibernate not to map a class property

问题描述

我有一个用流利的NHibernate映射一类，但我想在类的属性之一，由映射被忽略。

使用类和映射下面我得到这个错误：

<强> *以下类型可能不能用作代理：
iMasterengine.Data.Model.Calendar：方法get_HasEvents应该是虚拟的*

  //我的课
公共类日历：IEntity {
    公共虚拟INT标识{搞定;私人集; }
    公共虚拟字符串名称{;组; }
    公共虚拟字符串SITEID {搞定;组; }
    公共虚拟的IList＆LT; CalendarEvent＆GT;活动得到{;组; }
    //忽略此属性
    公共BOOL HasEvents {{返回Events.Count＆GT; 0; }}
}//我的映射
公共类CalendarMap：ClassMap＆LT;日历和GT; {
    公共CalendarMap（）{
    ID（X =＆GT; x.Id）;
    地图（X =＆GT; x.Name）;
    地图（X =＆GT; x.SiteId）;
    的hasMany（X =＆GT; x.Events）.Inverse（）;
        //我该怎么把这里要告诉NHibernate的
        //不理我HasEvents的财产？
    }
}
 

解决方案

  map.IgnoreProperty（P =＆GT; p.What）;
 

I have a class that is mapped in fluent nhibernate but I want one of the classes properties to be ignored by the mapping.

With class and mapping below I get this error:

*The following types may not be used as proxies: iMasterengine.Data.Model.Calendar: method get_HasEvents should be virtual*

//my class
public class Calendar : IEntity {
    public virtual int Id { get; private set; }
    public virtual string Name { get; set; }
    public virtual string SiteId { get; set; }
    public virtual IList<CalendarEvent> Events { get; set; }
    //ignore this property
    public bool HasEvents { get { return Events.Count > 0; } }
}

//my mapping
public class CalendarMap : ClassMap<Calendar> {
    public CalendarMap() {
    	Id(x => x.Id);
    	Map(x => x.Name);
    	Map(x => x.SiteId);
    	HasMany(x => x.Events).Inverse();
        //what do I put here to tell nhibernate
        //to ignore my HasEvents property?
    }
}

解决方案

map.IgnoreProperty(p => p.What);
