本文实例讲述了C#编程实现QQ界面的方法。分享给大家供大家参考，具体如下：
步骤:
1.新建一个页面,假如说叫VerticalMenu
2.把html代码copy到html代码区
3.把LoadTopMenu方法copy到cs代码区
4.运行即可
1.html代码
<STYLE type="text/css">
A:link {}{ COLOR: #000000; FONT-SIZE: 12px; TEXT-DECORATION: none}
A:visited {}{ COLOR: #000000; FONT-SIZE: 12px; TEXT-DECORATION: none}
A:hover {}{ COLOR: #006CD9; FONT-SIZE: 12px; TEXT-DECORATION: none}
BODY {}{ FONT-SIZE: 12px;}
TD {}{ FONT-SIZE: 12px; line-height: 150%}
</STYLE>
