asp.net 在后台向前台head中添加 js、css引用的操作

 HtmlGenericControl js = new HtmlGenericControl("script");

js.Attributes["type"] = "text/javascript";

js.Attributes["src"] = "js/jquery.validate.js";

HtmlGenericControl mes = new HtmlGenericControl("script");

mes.Attributes["type"] = "text/javascript";

mes.Attributes["src"] = "js/jquery.validate.messages_cn.js";

HtmlMeta meta1 = new HtmlMeta();

meta1.Name = "keywords";

meta1.Content = "L****";

HtmlMeta meta2 = new HtmlMeta();

meta2.Name = "description";

meta2.Content = "********";

Page.Header.Controls.Add(js);

Page.Header.Controls.Add(mes);

Page.Header.Controls.Add(meta1);

Page.Header.Controls.Add(meta2);

　　//如果你发现没有系统自带的方法或属性用如下方法：

HtmlGenericControl mes = new HtmlGenericControl("标签");

 mes.Attributes["属性"] = "**";

 mes.Attributes["属性"] = "***";
