在后台引入外部CSS文件

    protected void Page_Load(object sender, EventArgs e)

         {             if (!Page.IsPostBack)              {                  HtmlLink link = new HtmlLink();                  link.Attributes.Add("type", "text/css");                  link.Attributes.Add("rel", "stylesheet");                  link.Attributes.Add("href", url);//url为css路径                 this.Page.Header.Controls.Add(link);              }          }
