已搞定
string dirPath = System.Configuration.ConfigurationManager.AppSettings["dbbackuppath"];
        if (Directory.Exists(dirPath))
        {
            //获得目录信息
            DirectoryInfo dir = new DirectoryInfo(dirPath);
            //获得目录文件列表
            FileInfo[] info = dir.GetFiles("*.zip");
            Array.Sort(info, new FileComparer());             gridview1.DataSource = info;
            gridview1.DataBind();
        }
    
    private class FileComparer : IComparer
    {
        public FileComparer()
        {
        }
        public int Compare(object x, object y)
        {
            FileInfo infoX = x as FileInfo;
            FileInfo infoY = y as FileInfo;
            if (infoX.CreationTime > infoY.CreationTime)
                return -1;
            if (infoX.CreationTime < infoY.CreationTime)
                return 1;
            else
                return 0;
            
        }
    }
