数据缓加载和绑定表的特别方式

代码：

namespace BusinessLogic.BusinessObject<br /> {<br /> [Serializable]<br /> [System.Data.Linq.Mapping.Table(Name = "Task")]<br /> public class BusiTask : KLimsCore.Model.Task<br /> {<br /> private BusiSampleCollection busiSamples;<br /> public BusiSampleCollection BusiSamples<br /> {<br /> get<br /> {<br /> if (busiSamples == null)<br /> {<br /> busiSamples = new BusiSampleCollection();<br /> if (this.ID != 0)<br /> {<br /> busiSamples.FillCollection("TaskID=" + this.ID.ToString());<br /> }<br /> }<br /> return busiSamples;<br /> }<br /> set<br /> {<br /> busiSamples = value;<br /> }<br /> }</p> <p> public override string GetTableName()<br /> {<br /> return base.GetTableName();<br /> }</p> <p> }<br /> } 

重点在：

get<br /> {<br /> if (busiSamples == null)<br /> {<br /> busiSamples = new BusiSampleCollection();<br /> if (this.ID != 0)<br /> {<br /> busiSamples.FillCollection("TaskID=" + this.ID.ToString());<br /> }<br /> }<br /> return busiSamples;<br /> } 

另外

[System.Data.Linq.Mapping.Table(Name = "Task")]

指明了与数据库哪个表绑定。
