asp.net 後台新增CSS、JS、Meta標籤

下面是從Asp.net 後台加入CSS、JS、Meta標籤的寫法，我們這裡寫成函式方便以後使用。如果函數放在頁面類別中， Page參數也可以不要。

先導入命名空間 using System.Web.UI.HtmlControls;

/// <summary>
 /// 添加JS脚本链接
        /// </summary>
        /// <param name="page">页面</param>
        /// <param name="url">路径</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脚本内容
        /// </summary>
        /// <param name="page">页面</param>
        /// <param name="content">脚本内容</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样式链接
        /// </summary>
        /// <param name="page">页面</param>
        /// <param name="url">路径</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样式内容
        /// </summary>
        /// <param name="page">页面</param>
        /// <param name="content">样式内容</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标签
        /// </summary>
        /// <param name="page">页面</param>
        /// <param name="name">Meta名字</param>
        /// <param name="content">Meta内容</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);
        }
