VS2005中的类型化数据集 [英] Typed DataSets in VS2005

问题描述

大家好，


这篇文章与我之前关于DLL的

配置文件的帖子有点相关。

有没有人知道如何使用VS2005的新DataSet

设计器创建类型化数据集，但能够通过

配置配置连接字符串文件？设计者似乎将连接字符串硬编码到

数据集本身，这是不对的。


由VS2005创建的类型化数据集附带一个dll.config文件看起来好像是b $ b，好像它正在尝试做类似的事情，并且在编译时使用

可执行文件，但是改变那里的连接字符串

似乎没有任何效果。我们已经看到很多人问这个问题，但是还没有找到任何人接听它。

提前谢谢


Peter

解决方案

VSS 2005支持自动生成dataaccess图层..在这种情况下

你是可以自由更改硬编码连接字符串的代码，这样它就会从配置文件中读取它（显然你必须再次更改

代码）再次创建/编辑数据集。


在我的观点中，如果你是快速概念演示或工作的话，自动生成的代码是非常好的原型..但是如果你想要开发一个真正可扩展的大型系统，那么我宁愿

建议你拥有自己的数据访问层，的确可以从数据访问应用程序块或企业库获得一些

的帮助。

你会得到那个c有可能开发一个灵活的数据访问层..我用我的经验告诉你这个，如果你使用自动生成的代码

你有时会遇到瓶颈问题你的代码..

你的意思是说只需通过VSS IDE创建一个类型化的DataSet

连接字符串??


我在这里错过了一些东西.. ??谁能在这里帮助我.. ??

Hi all,

This post is sort of tangentially related to my earlier posts on
configuration files for DLLs.

Does anyone know how to create typed DataSets using VS2005''s new DataSet
designer, but with the ability to configure the connection string via a
config file? The designer seems to hard-code the connection string into the
dataset itself, which just can''t be right.

The typed DataSets created by VS2005 comes with a dll.config file that looks
as though it''s trying to do something like that, and which is put with the
executable at compile time, but altering the connection string in there
doesn''t appear to have any effect. We''ve seen lots of people asking this
question, but haven''t found anyone answering it yet.
Thanks in advance

Peter

VSS 2005 support auto generating the dataaccess layer .. and in that case
you are free to change the code where it hardcode the connection string so
that it will read it from a config file (obviously you have to change the
code again if you have to create/ edit the dataset again.

In my view point the automatically generated code is very good if you are
heading toward a quick concept demo or a working prototype.. but if you are
looking to develop a real extensible large-scale system, then I rather
advice you to have your own data access layer, indeed you may have some
assistance from the Data access Applcation Blocks or enterprise library.
There you will get that chance of developing a flexible dataaccess layer.. I
am telling this with my experience and if you go with the auto geneated code
you will at times drive in to bottleneck of your code..

Thanks Nirosh, but I''m not sure I understood all that.

I''m only talking about a typed DataSet: not about the entire data access
layer - which we code ourselves and which uses many typed datasets. At
least that was the case until now. If typed datasets now have the
connection string hard coded into them, we''ll definitely not be using them
any more - for security reasons apart from anything else.

You mean to say that just creating a typed DataSet via VSS IDE add the
connection string to it??

Am I missing some thing here.. ?? can anyone else assist me here..??
