关于留言本的实现，请各位高手帮我填写关键代码
我在网上下载了一个留言本的代码，由于是VB 语言，我想改为c#
index.aspx 文件如下：
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.
<script runat="server">
</script>
<html xmlns="http://www. >

<style type="text/css">

.style12 {font-size: 14px}
.style13 {color: #666666; font-size: 14px; }
-->
</style>
