classes

I am new in C# programming and in OOP. I need to dive into web applications for my company, and I need to do it fast and correct.

So even that I know ASP.NET MVC is the way to go, I want to start with some simple applications with ASP.NET Webforms and then advance to MVC logic.

Also regarding my db classes: I plan to create common database classes in order to be able to use them either from WinForms or ASP.NET applications.

I also know that the way to go is to learn about ORM and EF. BUT I also want to start from where I am feeling comfortable and that is the traditional ADO.NET way.

So about my Data Access Layer classes:

Should I return my results in datasets or arraylists/lists?
Should my methods do their own connect/disconnect from the db, or have separate methods and let the application maintain the connection?

Dynamic Type to do away with Reflection

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
