Answer 1

it is works for me

        using System;

        using System.Threading;
        using System.Threading.Tasks;

        namespace TaskTest2
        {

            class Program
            {
                static ManualResetEvent mre = new ManualResetEvent(false);
                static void Main(string[] args)
                {

                   mre.Set();
                   Task.Factory.StartNew(() =>
                    {
                        while (true)
                        {
                            Console.WriteLine("________________");
                            mre.WaitOne();
                        }

                    } );

                    Thread.Sleep(10000);
                    mre.Reset();
                    Console.WriteLine("Task Paused");
                    Thread.Sleep(10000);
                    Console.WriteLine("Task Will Resume After 1 Second");
                    Thread.Sleep(1000);
                    mre.Set();

                    Thread.Sleep(10000);
                    mre.Reset();
                    Console.WriteLine("Task Paused");


                    Console.Read();
                }
            }
        }
