Use of Switch Statement and Ternarry operator with Statement Lambda using C#

The below code will show the way to use Switch Statement and Ternary operator with Statement Lambda using C#

using System;
using System.Collections.Generic;
using System.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var personData = new List<PersonMaster>();

            //populating some data
            Enumerable
                .Range(1, 10)
                .ToList()
                .ForEach(
                            i =>
                            personData.Add(new PersonMaster
                            {
                                PersonID = i,
                                PersonName = string.Concat("Person ", i),
                                Age = 14+i
                            })
                        );

            //Use of Statement Lambda
            var eligiblePersonData = new List<EligiblePerson>();

            personData
        .ToList()
        .ForEach(i =>
        {

           switch(i.Age < 18 ? 0:1) // note the way the ternarry operator is used inside the switch statement as an expression
            {
                case 0:
                    Console.WriteLine("Mr. {0} is not eligible to case vote as his age is {1} which is under 18", i.PersonName, i.Age);
                    break;
                case 1:
                    eligiblePersonData.Add(new EligiblePerson
                    {
                        PersonID = i.PersonID,
                        PersonName = i.PersonName,
                        Age = i.Age
                    });
                    break;
            }
        });

            Console.ReadKey();
        }
    }

    //The main person model
    public class PersonMaster
    {
        public int PersonID { get; set; }
        public string PersonName { get; set; }
        public int Age { get; set; }

    }

    //Eligible Person Model
    public class EligiblePerson
    {
        public int PersonID { get; set; }
        public string PersonName { get; set; }
        public int Age { get; set; }
    }
