so let's do just that and implement the IEnumerable Interface
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
namespace pc.linq01
{
class Person
{
public string
FirstName { get; set; }
public string LastName
{ get; set; }
public string Fullname
{
get { return $"{FirstName} {LastName}"; } }
public Person(string
FirstName, string LastName)
{
this.FirstName = FirstName;
this.LastName = LastName;
}
}
class People : IEnumerable<Person>
{
Person[] ppl;
public IEnumerator<Person> GetEnumerator()
{
for (int i = 0; i
< ppl.Length; i++)
yield return ppl[i];
}
IEnumerator IEnumerable.GetEnumerator()
{
return GetEnumerator();
}
public People(params Person[] ppl) {
this.ppl = ppl;
}
}
class Program
{
static void Main(string[] args)
{
var ppl = new People(new Person("Pawel", "Chooch"),
new Person("Magda","Tyvoniuk"),
new Person("Jake","Tyvonuik"),
new Person ("Adam","Chooch"));
var choochs1 = from p in ppl
where p.LastName == "Chooch"
select p;
var choochs2 = ppl.Where(p => p.LastName == "Chooch");
foreach (var c in choochs1)
Console.Write(c.Fullname+ " ");
Console.WriteLine("\n");
foreach (var c in choochs2)
Console.Write(c.Fullname + " ");
Console.WriteLine("\n");
}
}
}
