本文來源于網頁設計愛好者web開發社區http://www.html.org.cn收集整理，歡迎訪問。如果要表示一對多的對象結構，我們可以采用如下的方式（表明了一個入庫單的結構，這個入庫單包含了入庫單頭和相關明細）：
public class form : persistencecapable
{
private entitydata form;
private formdetail formdetail;
#region 構造函數
public form() : this(true)
{}
public form(bool autoinit)
{
form=entityprototypemanager.getemptyentity("form");
if(autoinit)
form.newrecord("form");
}
public form(entitydata entity)
{
form=entity;
}
#endregion
#region 屬性
public string formid
{
get{return form["formid","form"].tostring();}
set{form["formid","form"]=value;}
}

{
get{return form.getdatetime("formtime","form");}

}
public formdetail formdetail
