Hello,
If i add to my arraylist some phone numbers
How do i

1. Check for the phone numbers that dont meet the lenght requirement
2. Remove the unwanted numbers

Here is part of my code


class Program
{
static void Main(string[] args)
{
ArrayList Phone_numbers = new ArrayList(); Phone_numbers.Add(new numbers("USA"));
((USA)Phone_numbers[0]).colNumber.Add(new Number("Johnson", 12));

((USA)Phone_numbers[0]).colNumber.Add(new Number("Michael", 14));

((USA)Phone_numbers[0]).colNumber.Add(new Number("John", 15));


Phone_numbers.Add(new numbers("UK"));
((UK)Phone_numbers[1]).colNumber.Add(new Number("Johnson", 19));

((UK)Phone_numbers[1]).colNumber.Add(new Number("Michael", 17));

((UK)Phone_numbers[1]).colNumber.Add(new Number("John", 14));

Yes O !

It all depends on your Numbers and Number classes and how they work. We have no idea because we don't have the code. You are just using the ArrayList, it appears, to hold a list of Numbers objects, so you'd need to see what properties and methods are available in your Numbers and Number classes to validate them and/or remove and edit them. This really has nothing to do with an ArrayList.
