How to Get a Sublist in C#

Question

I have a List and i need to take a sublist out of this list. Is there any methods of List available for this in .NET 3.5?

Answer 1

Your collection class could have a method that returns a collection (a sublist) based on criteria passed in to define the filter. Build a new collection with the foreach loop and pass it out.

Or, have the method and loop modify the existing collection by setting a "filtered" or "active" flag (property). This one could work but could also cause poblems in multithreaded code. If other objects deped on the contents of the collection this is either good or bad depending of how you use the data.
