Question

As I’m building my first UI program in C#, I am facing some troubles!
Assuming I have two Classes (Country, City) then I set each new Country object in An ArrayList created before and named CountryList as following:

public static ArrayList CountryList = new ArrayList();

Country c1 = new Country(string name); // Creating Country object

CountryList.Add(c1); // Store the Object c1 in ArrayList

As every Country has its own Cities so I can’t create an ArrayList to store all City objects together !
Then, I want like a Sub-ArrayList in ArrayList.

Answer 1

How about this?

public class City
{
  public string Name {get; set;}
}

public class Country 
{ 
  public string Name {get; set;}

  public List<City> Cities {get; set;}
}
