如何将关系数据导入对象？ [英] How to get relational data into an object?

问题描述

是否存在将关系数据从

数据库和对象中获取的模式或最佳实践？


有问题的对象具有公共属性看起来像这样：


_stringName

cfgObjects的_ArrayList

_DateTime

_Integer


cfgObject如下所示：


_stringCfgName

_ArrayList1 of strings

_ArrayList2 of strings

_bool1

_bool2

初始化这些对象的数据存储在带有
$ b $的类型化数据集中b约束和关系。


我想我可以填充一个DataTable并在

对象的构造函数中迭代它但是，作为C＃的新手，我的猜测是那里有一些

模式或练习，甚至是FCL中的一些课程，它们有更好的方式。


是否有标准（或更好）的方法从关系数据中获取对象？


提前致谢。

Is there a Pattern or best Practice for getting relational data out of a
database and into an object?

The object in question has public properties that look like this:

_stringName
_ArrayList of cfgObjects
_DateTime
_Integer

the cfgObject looks like this:

_stringCfgName
_ArrayList1 of strings
_ArrayList2 of strings
_bool1
_bool2

The data that initializes these objects is stored in a typed DataSet with
constraints and relations.

I suppose I could populate a DataTable and iterate through it in the
object''s constructor but, as a newbie to C#, my guess is there''s some
pattern or practice out there, or even some class in the FCL, that has a
better way.

Is there a standard (or better) way to get an object from relational data?

Thanks in advance.

推荐答案

Google for C＃ORM或OR / M - 对象关系映射，和实体对象，

等。

有很多要涵盖的内容！如果确定有人会用他们最喜欢的

方法和产品插入...

新闻：AN ****************************** @ comcast.com。 ..

Google for C# ORM or OR/M - object-relational mapping, and "entity objects",
and the like.
There''s a lot to cover! If sure people will chime in with their favorite
methods and products...

你好deko，


只是为了添加到Mike post abt O / R mapping I建议使用NHibernate和

CodeSmith与第三方模板

Hello deko,

Just to add to Mike post abt O/R mapping I recomend to use NHibernate and

CodeSmith听起来很棒（它应该是100美元）。我会试用

版本旋转。


感谢您的提示。

CodeSmith sounds great (it ought to be for 100 bucks). I''ll take the trial
version for a spin.

Thanks for the tip.
