public class form : persistencecapable
{
private entitydata form;
private formdetail formdetail;
#region 构造函数
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 属性
public string formid
{
get{return form["formid","form"].tostring();}
set{form["formid","form"]=value;}
}
public datetime formtime
{
get{return form.getdatetime("formtime","form");}
set{form["formtime","form"]=value;}
}
public formdetail formdetail
{
get
{
if(formdetail==null)
{
formdetail=new formdetail(form);
}
return formdetail;
}
}
#endregion
#region persistencecapable 成员
public int objectcount
{
get
{
return form.entitycount;
}
}
public entitydata entitydata
{
get
{
return form;
}
set
{
form=value;
}
}
public bool next()
{
return form.next("form");
}
public void first()
{
form.first("form");
}
public void addnew()
{

}
#endregion
}
