 var task = Task.Run(() =>
            {
                System.Threading.Thread.Sleep(1000 * 40);
                Console.Write("111");
            });
            var taskSuccess = task.Wait(1000 * 30);
            if (!taskSuccess)
            {
                Console.WriteLine(task.IsCompleted);
                Console.Write("222");
            }

 结果：

False　　222　

var task = Task.Run(() =>
            {
                System.Threading.Thread.Sleep(1000 * 20);
                Console.WriteLine("111");
            });
            var taskSuccess = task.Wait(1000 * 30);
            if (!taskSuccess)
            {
                Console.WriteLine(task.IsCompleted);
                Console.Write("222");
            }
            else
            {
                Console.WriteLine(task.IsCompleted);
                Console.WriteLine("333");
            }
