modeling

Hi,

I have a few classes:

Article
-------
Content
ID

Magazine
--------
Name
Code

And 3 tables in database:

Articles
Magazines
ArticlesInMagazines (two fields: IDArticle and CodeMagazine)

In my app, I've got a module to manage Articles, and a datagridview to relate their associated magazines

DataGridView has twofields:

MagazineCode
IsPublished (indicates articles which have been published in this magazine).

The same article can be in many magazines (1:n)

How would you implement on model ?

Article have to has a field : List ?? I am concerned because Magazine associates Articles

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
