上传附件功能？

Question

有哪位仁兄实现过类似于163邮箱那样的添加附件功能啊，就是选择完文件后就能直接上传

Answer 1

 System.IO.File.Copy(FileName, phyPath, true);FileName//你的文件路径
phyPath //你要复制到服务器的路径.或者你就用FileUpload控件

Answer 2

动态添加rows,模仿网易邮箱添加附件功能.<script language=javascript> 
             
    function AddRow() 
    {     
        var newRow = document.getElementById("row").cloneNode(true);                 
       table1.appendChild(newRow);                 
    } 
</script>http://www.cnblogs.com/tangdebing/archive/2008/01/08/728954.html
