Asp.net 后台添加CSS、JS、Meta标签的写法，我这里写成函数方便以后使用。如果函数放在页面类中， Page参数也可以不要。
首先导入命名空间 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); }
