这是一个模仿我的实际案例流程的程序:

using System;
using System.Threading.Tasks;

namespace TestAsync
{
    interface IInterface
    {
        Task<int> DoSomething(int i);
    }

    class MyClass : IInterface
    {
        public async void MainAsync()
        {
            var i = 1;
            Console.WriteLine("Start MainAsync:" + i);
            var t = DoSomething(i);
            Console.WriteLine("After DoSomething: " + i );
            i = await t;
            Console.WriteLine("Done waiting: " + i);
        }

        public async Task<int> DoSomething(int i)
        {
            i = i + 1;
            Console.WriteLine("In Something:" + i);
            await Task.Delay(1000);
            Console.WriteLine("After Long Process: " + i);
            return i;
        }
    } …
