C# Task async 한정자와 await 연산자 사용하기.

using System;
using System.Threading.Tasks;

namespace ThreadNTask
{
    class Program
    {
        static void Main(string[] args)
        {
            Caller();

            Console.ReadLine();
        }

        async static private void MyMethodAsync(int count)
        {
            Console.WriteLine("C");
            Console.WriteLine("D");

            await Task.Run(async() =>
            {
                for(int i = 1; i < count; i++)
                {
                    Console.WriteLine($"{i}/{count}.");
                    await Task.Delay(1000);
                }
            });

            Console.WriteLine("G");
            Console.WriteLine("H");
        }

        static void Caller()
        {
            Console.WriteLine("A");
            Console.WriteLine("B");

            MyMethodAsync(3);

            Console.WriteLine("E");
            Console.WriteLine("F");
