代碼如下:
    protected void ReadFile()     //讀取文件夾，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] + " <br/ >");
        //}
        //Response.Write("Directorys count：" + Directorys.Length + "個  <br/ >--------- <br >");
        string[] Files = Directory.GetFiles(absSavePath + @"" + Page.User.Identity.Name, "*");
        outstring.Append("<ul>");
        for (int i = 0; i < Files.Length; i++)
        {
            if (Path.GetFileName(Files[i]) != "Thumbs.db")
            {
                outstring.Append("<li><img src=/"common/" + Path.GetFileName(Files[i]) + "/" style=/"width:100px;height:100px;/" /><br/><input type=/"checkbox/" value=/"common/" + Path.GetFileName(Files[i]) + "/" name=/"picname/" onclick=/"getpicid();/" id=/"imgid" + i.ToString() + "/" /><label for=/"imgid" + i.ToString() + "/">" + Path.GetFileName(Files[i]) + "</label></li>");
            }
        }
        outstring.Append("</ul>");
        Response.Write(outstring.ToString());
    }

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

代碼如下:
//循環遍歷復選框
<script language="javascript" type="text/javascript" defer="defer">
    var imgnum = document.getElementsByTagName("input");
    var imgids = "";
