Answer 2

给你贴个Kindeditor里的FileManager的代码 你自己瞧吧public static string FileManager(HttpContextBase hc)
        {
            context = hc;
            string aspxUrl = context.Request.Path.Substring(0, context.Request.Path.LastIndexOf("/") + 1);            //根目录路径，相对路径            //根目录URL，可以指定绝对路径，比如 http://www.yoursite.com/attached/
            string rootUrl = aspxUrl + rootPath;
            //图片扩展名
            string currentPath = "";
            string currentUrl = "";
            string currentDirPath = "";
            string moveupDirPath = "";            //根据path参数，设置各路径和URL
            string path = context.Request.QueryString["path"];
            path = string.IsNullOrEmpty(path) ? "" : path;
            if (path == "")
            {
                currentPath = context.Server.MapPath(rootPath);
                currentUrl = rootUrl;
                currentDirPath = "";
                moveupDirPath = "";
            }
            else
            {
                currentPath = context.Server.MapPath(rootPath) + path;
                currentUrl = rootUrl + path;
                currentDirPath = path;
                moveupDirPath = Regex.Replace(currentDirPath, @"(.*?)[^\/]+\/$", "$1");
            }            //排序形式，name or size or type
            string order = context.Request.QueryString["order"];
            order = string.IsNullOrEmpty(order) ? "" : order.ToLower();            //不允许使用..移动到上一级目录
            if (Regex.IsMatch(path, @"\.\."))
            {
                context.Response.Write("访问被拒绝。");
                context.Response.End();
            }
            //最后一个字符不是/
            if (path != "" && !path.EndsWith("/"))
            {

                context.Response.End();
