如何根据日期每天返回不同的图像

Question

我想根据c＃中的日期返回30张图片 可能吗 ？ 像那样

Bitmap bmp = new Bitmap(DateTime.Now.ToString().Substring(0, 2).ToString() + ".png");

Answer 1

尝试这样的事情

     const string FOLDER = @"c:\temp";
    static void Main(string[] args)
    {
        DirectoryInfo info = new DirectoryInfo(FOLDER);
        FileInfo[] files = info.GetFiles("*.png", SearchOption.TopDirectoryOnly);
        DateTime today = DateTime.Now;
        string[] filteredFiles = files.Where(x => x.LastWriteTime >= today.AddDays(-30)).Select(y => y.FullName).ToArray();
    }
