这段代码是同步的还是异步的？

Question

namespace SampleThreadTaskClass
{
    class Program
    {
        static void Main(string[] args)
        {           
            Task task = new Task(ProcessDataAsync);
            task.Start();

            Console.WriteLine("Enter any key");

            string input = Console.ReadLine();
            Console.WriteLine("You entered: " + input);

            Console.ReadLine(); 
        }

        static async void ProcessDataAsync()
        {
            for (int i = 0; i < 20; i++)
            {
                Thread.Sleep(500);
                Console.WriteLine("processing... " + i);
            }
        }
    }
}

是的。是的。thread.sleep()不是异步的。

参见说明:https://msdn.microsoft.com/en-us/library/hh156528.aspx#示例

尝试delay,然后可以在前面添加await,

await Task.Delay(10000);
