问题描述

嗨伙计


任何人都可以指点我的方向，如何制作一个可用于新ASP的

数据层。 NET 2.0数据组件

（GridView等）？


我问的原因是因为我希望完全拥有我的数据层

单独组装。但是，这似乎不太可能。让我来解释....


每个描述如何做到这一点的网站似乎都遵循相同的模式 -

网站的一半谈论数据层的方式然后，当它出现一个例子时，他们会直接在页面上删除一个SQLDataSource或一个ObjectDataSource

。我在这里遗漏了一些东西 - 对我来说这不是数据

层。


另外，当你在ASP.NET应用程序中创建一个DataSet时，你得到的方法与普通程序集中的DataSet不同。
方法。事实上，在一个ASP.NET

DataSet中，你甚至没有得到任何C＃代码，这意味着你不能在

普通代码中使用它（所以你不能围绕它创建一个包装器。它还意味着

ASP.NET组件不能使用程序集DataSet（因为它不会生成插入和删除方法） - 它只会生成"&的GetData QUOT;并且

更新。


我想我错过了一些信息，所以如果你能够支持
就可以了帮助！


谢谢

Hi folks

Can anyone point me in the direction of any information on how to make a
data layer which will work with the new ASP.NET 2.0 data components
(GridView, etc)?

The reason I ask is because I want to have my data layer in a totally
separate assembly. However, this doesn''t seem possible. Let me explain....

Every site which describes how to do this seems to follow the same pattern -
half the site talks about how data layers are great, etc. Then, when it
comes to an example, they drop an SQLDataSource or an ObjectDataSource
directly on the page. Am I missing something here - to me this isn''t a data
layer.

Also, when you create a DataSet in an ASP.NET application, you get different
methods to that of a DataSet in a normal assembly. In fact, in an ASP.NET
DataSet you don''t even get any C# code which means that you can''t use it in
normal code (so you can''t create a wrapper around it). It also means that
ASP.NET components won''t work with an assembly DataSet (since it doesn''t
generate Insert and Delete methods) - it only generates "GetData" and
"Update".

I think I am missing some chunk of information so would be great if you
could help!

Thanks

Will

推荐答案

是当你设计一个你想要抽象的灵活架构时，所有拖放设计师的东西都不实用或不可用。


如果你想要它做得对，你需要自己完成这一切，而不需要

设计师为你做这一切。自己写下插入/更新/删除/选择

语句等。

Yes, all the drag and drop designer stuff is not practical or usable when
you are designing a flexible architecture that you want to abstract.

If you want it done right, you need to do it all yourself without having the
designer do it all for you. Write your insert/update/delete/select
statements yourself, etc.

是ObjectDataSource是为多层设计的。


" Bruce Barker"写道：

Yes ObjectDataSource is designed for multi-layers.
