    protected void ReadFile()     //读取文件夹，文件
    {
        string savePath = @"common";
        StringBuilder outstring = new StringBuilder();
        string absSavePath = Server.MapPath(savePath);
        string[] Directorys = Directory.GetDirectories(absSavePath + @"/" + Page.User.Identity.Name);
        //for (int i = 0; i < Directorys.Length; i++)
        //{
        //    Response.Write(Directorys[i] + "
");
        //}
        //Response.Write("Directorys count：" + Directorys.Length + "个 
---------
");
        string[] Files = Directory.GetFiles(absSavePath + @"" + Page.User.Identity.Name, "*");
        outstring.Append("

");
        for (int i = 0; i < Files.Length; i++)
        {
            if (Path.GetFileName(Files[i]) != "Thumbs.db")
            {
                outstring.Append("
• 
  " + Path.GetFileName(Files[i]) + "
");
            }
        }
        outstring.Append("

");
        Response.Write(outstring.ToString());
    }

//删除文件
        string[] strpicname = Request["imgids"].Split(new char[] { ',' });
        for (int i = 0; i < strpicname.Length; i++)
        {
            File.Delete(Server.MapPath(strpicname[i].ToString()));
        }

//循环遍历复选框
