下面是從Asp.net 后臺添加CSS、JS、Meta標簽的寫法，我們這里寫成函數方便以后使用。如果函數放在頁面類中， Page參數也可以不要。
首先導入命名空間 using System.Web.UI.HtmlControls;

??????? /// <summary>
??????? /// 添加JS腳本鏈接
??????? /// </summary>
??????? /// <param name="page">頁面</param>
??????? /// <param name="url">路徑</param>
??????? public void AddJS(System.Web.UI.Page page, string url)
??????? {
??????????????? HtmlGenericControl jsControl = new HtmlGenericControl("script");
??????????????? jsControl.Attributes.Add("type", "text/javascript");
??????????????? jsControl.Attributes.Add("src", url);
??????????????? page.Header.Controls.Add(jsControl);
??????? }
??????? /// <summary>
??????? /// 添加JS腳本內容
??????? /// </summary>
??????? /// <param name="page">頁面</param>
??????? /// <param name="content">腳本內容</param>
??????? public void AddScript(System.Web.UI.Page page, string content)
??????? {
??????????????? HtmlGenericControl scriptControl = new HtmlGenericControl("script");
??????????????? scriptControl.Attributes.Add("type", "text/javascript");
??????????????? scriptControl.InnerHtml = content;
??????????????? page.Header.Controls.Add(scriptControl);
??????? }
??????? /// <summary>
??????? /// 添加CSS樣式鏈接
??????? /// </summary>
??????? /// <param name="page">頁面</param>
??????? /// <param name="url">路徑</param>
??????? public void AddCss(System.Web.UI.Page page, string url)
??????? {
??????????????? HtmlLink link = new HtmlLink();
??????????????? link.Href = url;
??????????????? link.Attributes.Add("rel", "stylesheet");
??????????????? link.Attributes.Add("type", "text/css");
??????????????? page.Header.Controls.Add(link);
??????? }
??????? /// <summary>
??????? /// 添加CSS樣式內容
??????? /// </summary>
??????? /// <param name="page">頁面</param>
??????? /// <param name="content">樣式內容</param>
??????? public void AddStyle(System.Web.UI.Page page, string content)
??????? {
??????????????? HtmlGenericControl styleControl = new HtmlGenericControl("style");
??????????????? styleControl.Attributes.Add("type", "text/css");
??????????????? styleControl.InnerHtml = content;
??????????????? page.Header.Controls.Add(styleControl);
??????? }
??????? /// <summary>
??????? /// 添加Meta標簽
??????? /// </summary>
??????? /// <param name="page">頁面</param>
??????? /// <param name="name">Meta名字</param>
??????? /// <param name="content">Meta內容</param>
??????? public void AddMeta(System.Web.UI.Page page, string name, string content)
??????? {
??????????????? HtmlMeta meta = new HtmlMeta();
??????????????? meta.Name = name;
??????????????? meta.Content = content;
??????????????? page.Header.Controls.Add(meta);
??????? }
