C#Task中await和.Result和GetAwaiter().GetResult()方法的区别

await不会阻塞调用它的线程，而GetAwaiter().GetResult()和.Result则会阻塞调用它的线程，但都会阻塞当前线程

        private  static  void Main()
        {
            Console.WriteLine("开始");
            test1();
            Console.WriteLine("第一个任务结束了");
            test2();
            Console.WriteLine("第二个任务结束了");
            test3Async();
            Console.WriteLine("第三个任务结束了");
            Console.ReadKey();
        }  

        public static void test1()
        {
            Console.WriteLine("第一个任务开始了");
            Task.Run(() =>
            {
                Thread.Sleep(1000);
                Console.WriteLine(1111);
                
            }).GetAwaiter().GetResult();
            Console.WriteLine("第一个任务快完了");
            Thread.Sleep(2000);
        }
        public static async Task<bool> test2Async()
        {
            Console.WriteLine("第二个任务开始了");
            Thread.Sleep(1000);
            Console.WriteLine(2222);
            return true;
        }

        public static async Task test3Async()
        {
            Console.WriteLine("第三个任务开始了");
            await Task.Run(() =>
            {
                Thread.Sleep(1000);
                Console.WriteLine(3333);
            });
            Console.WriteLine("第三个任务快完了");
            Thread.Sleep(2000);
        }
        public static void test2()
        {
            var a = test2Async().Result;
            Console.WriteLine("第二个任务快完了");
            Thread.Sleep(2000);
        }

如有错误，恳请指正！！！
