Answer 1

试试这样

     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();
    }
