Question

What is the best or easier container I could use to retrieve the the last entry position ?

Or there are not better or easier than using Count ? is it ok to rely on count ?

Example:

List<Class> myList = new List<Class>();
int lastEntry = myList.Count - 1;
Message.Box(myList[lastEntry].Name);

There is no concurrent write to this list mainly reading.

Answer 1

Using Count is fine for List<T> — or anything else that implements ICollection<T> or ICollection — but you have an off-by-one error in your code. It should be…

int lastEntry = myList.Count - 1;    // index is zero-based
