Add CSS, JS, Meta tags in asp.net background

The following is how to add CSS, JS, and Meta tags from the Asp.net backend. We write them as functions here for easy use later. If the function is placed in the page class, the Page parameter is optional.

First import the namespace 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);
        }
