class vs interface

[future3839]

hi, could you please some one tell me when should I use interface? what is it,exactly?

[Luc Pattyn]

No thanks. If one answers one such question, you'll be back asking about inner classes, abstract classes, patterns, inversion of control, and many more. Get yourself an introductory book to C# and study it, there is much to learn, and it doesn't make sense for anyone to write it down here piece by piece. Now when you have a specific question relating to some code of yours, we all will be willing to help you out. :)

Please use <PRE> tags for code snippets, they preserve indentation, improve readability, and make me actually look at the code.

Always.

Go to a CLASS or INTERFACE with a book! Better still, CP Archive has This[^] article.

Ditto what everyone else has said. Also, I think at your stage of learning it is very informative to look closely at some of the existing interfaces in the framework, and how they are implemented. An example, one of many off the top of my head, is say IComparable and/or IComparable<T>. Then read the msdn blurb on the List<T>.Sort() method, and think about how implementing one of those interfaces in some class you design makes it possible to sort a list of instances of that class. Again, I am not contradicting the good advice given by the previous posts, I am simply saying that studying some of the built-in interfaces and finding examples of their usage can be ONE aid to understanding interfaces in general.
