C#. IEnumerable и Ienumerator

Posted on 23.08.2017 by Stanislav_Panteleev

To support foreach in some classes – see example below Ok

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace IEnumerable123
{
    class Program
    {
        static void Main(string[] args)
        {

            Garage carLot = new Garage();
            foreach (Car c in carLot) { Console.WriteLine(c.Name); } // <<< Here !!!
            Console.ReadLine();

        }
    }


    public class Garage: IEnumerable
    {

        private Car[] carArray = new Car[4];

        public Garage() {

            carArray[0] = new Car("name1");
            carArray[1] = new Car("name2");
            carArray[2] = new Car("name3");
            carArray[3] = new Car("name4");
        }

        public IEnumerator GetEnumerator() {

            return carArray.GetEnumerator();
        }

    }

    public class Car {
        public string Name{get; set;}
        public Car(string aname){ Name = aname; }
    }

}

using System;

using System.Collections;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace IEnumerable123

{

class Program

{

static void Main(string[] args)

{

Garage carLot = new Garage();

foreach (Car c in carLot) { Console.WriteLine(c.Name); } // <<< Here !!!

Console.ReadLine();

}

public class Garage: IEnumerable

{

private Car[] carArray = new Car[4];

public Garage() {

carArray[0] = new Car("name1");

carArray[1] = new Car("name2");

carArray[2] = new Car("name3");

carArray[3] = new Car("name4");

}

public IEnumerator GetEnumerator() {

return carArray.GetEnumerator();

}

public class Car {

public string Name{get; set;}

public Car(string aname){ Name = aname; }

}

Not Ok

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace IEnumerable123
{
    class Program
    {
        static void Main(string[] args)
        {

            Garage carLot = new Garage();
            foreach (Car c in carLot) { Console.WriteLine(c.Name); } // Garage should support IEnumerator
            Console.ReadLine();

        }
    }


    public class Garage
    {

        private Car[] carArray = new Car[4];

        public Garage() {

            carArray[0] = new Car("name1");
            carArray[1] = new Car("name2");
            carArray[2] = new Car("name3");
            carArray[3] = new Car("name4");
        }


    }

    public class Car {
        public string Name{get; set;}
        public Car(string aname){ Name = aname; }
    }

}

using System;

using System.Collections;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace IEnumerable123

{

class Program

{

static void Main(string[] args)

{

Garage carLot = new Garage();

foreach (Car c in carLot) { Console.WriteLine(c.Name); } // Garage should support IEnumerator

Console.ReadLine();

}

public class Garage

{

private Car[] carArray = new Car[4];

public Garage() {

carArray[0] = new Car("name1");

carArray[1] = new Car("name2");

carArray[2] = new Car("name3");

carArray[3] = new Car("name4");

}

public class Car {

public string Name{get; set;}

public Car(string aname){ Name = aname; }

}
