Here's a little snippet I use to extend a generic List class to have similar capabilites to the Stack class.
The Stack<T> class is great but it lives in its own world under System.Object. Wouldn't it be nice to have a List<T> that could do the same? Here's the code:
1: public static class ExtensionMethods
2: {
3: public static T Pop<T>(this List<T> theList)
4: {
5: var local = theList[theList.Count - 1];
6: theList.RemoveAt(theList.Count - 1);
7: return local;
8: }
9:
10: public static void Push<T>(this List<T> theList, T item)
11: {
12: theList.Add(item);
13: }
14: }
It's a simple extension but I've found it useful, hopefully you will too! Enjoy.
