IEnumerable Interface

Comment

/*
IEnumrable interface:

has a single method, "GetEnumerator" a single method that allows you to iterate over your class object using foreach.

You must implement this function.
*/

// For example, we will implement the IEnumerable interface in our home-made collection.

public class MyCollection:IEnumerable
  {
    private readonly int[] _list;

    public MyCollection(int size)
    {
      _list = new int[size];
    }
    
    public IEnumerator GetEnumerator()
    {
      foreach (var item in _list)
      {
        yield return item;
      }
    }
  }
  public class Program
  {
    static void Main(string[] args)
    {
      MyCollection list = new MyCollection(5);
      foreach (var variable in list)
        Console.WriteLine(variable); // 0 0 0 0 0
    }
  }
