1.使用Literal控件。
Literal与Label非常相似，区别在于Label会在输出后加上<span></span>标记，而Literal不会添加任何多余的标记。看代码：
前台：
<asp:Literal ID="ltPageTitle" runat="server" />
<asp:Literal ID="ltPagekeywords" runat="server" />
<asp:Literal ID="ltPagedescrip tion" runat="server" />
后台：
<asp:Literal ID="ltPageTitle" runat="server" />
<asp:Literal ID="ltPagekeywords" runat="server" />
<asp:Literal ID="ltPagedescrip tion" runat="server" />
ltPageTitle.Text = "<title>页面标题</title>";
ltPagekeywords.Text = "< name="keywords" content="关键词">";
ltPagedescrip tion.Text = "< name="descrip tion" content="内容描述">";
效果一定会让你满意的！
2. 使用H t m l M e t a类
设置Title ：
this .Header.Title = " 这是个Title测试 " ;
如果用了MasterPage可以这样用：
this .Page.Title = SiteMap.CurrentNode.Title;
动态设置Style：
Style style = new Style();style.ForeColor = System.Drawing.Color.Navy;style.BackColor = System.Drawing.Color.LightGray; // Add the style to the header for the body of the page this .Header.StyleSheet.CreateStyleRule(style, null , " body " );
动态加样式表：
HtmlLink link = new HtmlLink();link.Attributes.Add( " type " , " text/css " );link.Attributes.Add( " rel " , " stylesheet " );link.Attributes.Add( " href " , " ~/newstyle.css " ); this .Header.Controls.Add(link);
动态加meta tags ：
// Render: <meta name="keywords" content="Some words listed here" /> HtmlMeta meta = new HtmlMeta();meta.Name = " keywords " ;meta.Content = " Some words listed here " ; this .Header.Controls.Add(meta); // Render: <meta name="robots" content="noindex" /> meta = new HtmlMeta();meta.Name = " robots " ;meta.Content = " noindex " ; this .Header.Controls.Add(meta); // Render: <meta name="date" content="2006-03-25" scheme="YYYY-MM-DD" /> meta = new HtmlMeta();meta.Name = " date " ;meta.Content = DateTime.Now.ToString( " yyyy-MM-dd " );meta.Scheme = " YYYY-MM-DD " ; this .Header.Controls.Add(meta);
