Header中添加/title/Meta tages/CSS

设置Title ：

this.Header.Title="Title PAGE";

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);
