c#中关于改网页上文字的方法,急!!!
网址后面有个about_us.aspx?id=141,这id 141是怎么回事啊,但是我看他网页代码里是
<body>
<form id="form1" runat="server">
<div class="mainbox cont">
<uc5:top ID="top1" runat="server" />
<div class="homeUrl">
<asp:SiteMapPath ID="SiteMapPath1" runat="server"
SiteMapProvider="XmlSiteMapProvider">
</asp:SiteMapPath>
</div>
<div class="bodyc">
