在 C# 中从 main 调用异步函数 [重复]

Question

我正在尝试用 C# 围绕 async await 转转。我编写了这个有两个文件的小型 Windows 控制台应用程序。

Downloader.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace AsyncAwait
{
    public class Downloader
    {

        public async Task DownloadFilesAsync()
        {
            // In the Real World, we would actually do something...
            // For this example, we're just going to print file 0, file 1.
            await DownloadFile0();
            await DownloadFile1();
        }
        public async Task DownloadFile0()
        {
            Console.WriteLine("Downloading File 0");
            await Task.Delay(100);
        }

        public async Task DownloadFile1()
        {
            Console.WriteLine("Downloading File 1");
            await Task.Delay(100);
        }
    }
}

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace AsyncAwait
{
    class Program
    {
        static void Main(string[] args)
        {
            Downloader d = new Downloader();

        }
    }
}

我只想从我的main 调用函数DownloadFilesAsync()。我创建了Downloader 对象'd'。但是，由于它是 main 并且返回类型必须为 void，因此这是不可能的。有什么办法解决这个问题？

Answer 1

 Task.Run(async () => { await d.DownloadFilesAsync();}).Wait();
