C# 在C中从main调用异步函数#

我正试着用C#对

async wait

进行思考。我已经编写了这个小的windows控制台应用程序，它有两个文件

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);
        }
    }
}

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();

        }
    }
}

Program.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);
        }
    }
}

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

downloadFileAsync（）

。我已经创建了

下载程序
对象“d”。但是，由于它是main，并且返回类型必须为void，所以不可能。这有什么办法

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