是否可以从Windows Forms应用程序内的HttpContent流下载文件？

using System;
using System.Net.Http;
using System.Threading.Tasks;

public class Program
{
    public static async Task Main()
    {
        using (HttpClient client = new HttpClient())
        {
            HttpResponseMessage response = await client.GetAsync("http://example.com/file.txt");
            if (response.IsSuccessStatusCode)
            {
                HttpContent content = response.Content;
                using (var fileStream = System.IO.File.Create("downloaded_file.txt"))
                {
                    await content.CopyToAsync(fileStream);
                }
                Console.WriteLine("文件下载完成。");
            }
            else
            {
                Console.WriteLine("文件下载失败。");
            }
        }
    }
}
