Answer 1

private string GetFolderInfo(string path)
        {
            if (Directory.Exists(path)) //判断文件夹是否存在
            {
                //if (Directory.GetFileSystemEntries(path).Length == 0) //判断是否有子文件夹
                //    Response.Write("Folder " + path + " is empty");
                //else
                //{
                    string[] subdirectoryEntries = Directory.GetDirectories(path);
                    foreach (string subdirectory in subdirectoryEntries) //遍历文家夹
                    {
                        string[] fileNames = Directory.GetFiles(subdirectory); //获取该文家夹下得所有文件
                        foreach (string file in fileNames) //遍历文件
                        {
                           Response.Write(file);
                           rs = new ResourceServices();
                           if (rs.IsNull(System.IO.Path.GetFileName(file)) == null) //判断是否存在数据库
                           {
                               if (File.Exists(file))
                               {
                                   File.Delete(file);//删除图片
                                   Response.Write(" ----- 删除");
                               }
                                /*
                                * 处理遍历文件
                                * */
                            }
                            Response.Write("<br>");
                        }
                        GetFolderInfo(subdirectory);
                    //}

将图片命名：1.jpg、2.jpg......
拖一个Timer控件，双击进入事件
int MaxNumber=10;//假设共10张图片
ViewState["number"]=ViewState["number"]%MaxNumber+1；
Image1.ImageUrl=string。Format("../Image/{0}.jpg",viewSate["number"]);
