c# ienumerable for code example

Example 1: c# loop through list

using System;
using System.Collections.Generic;
 
namespace forgetCode {
    class program {
        public static void Main() {
 
            List<int> list = new List<int>();
            list.Add(1);
            list.Add(2);
            list.Add(3);
 
            foreach (int item in list) { // Loop through List with foreach
                Console.WriteLine(item);
            }
 
            for (int i = 0; i < list.Count; i++) { // Loop through List with for
                Console.WriteLine(list[i]);
            }
        }
    }
}

/*
Outputs:
1
2
3
1
2
3
*/

Example 2: c# implement ienumerable t

using System.Collections;

class MyObjects : IEnumerable<MyObject>
{
    List<MyObject> mylist = new List<MyObject>();

    public MyObject this[int index]  
    {  
        get { return mylist[index]; }  
        set { mylist.Insert(index, value); }  
    } 

    public IEnumerator<MyObject> GetEnumerator()
    {
        return mylist.GetEnumerator();
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return this.GetEnumerator();
    }
}
