1. 添加CSS样式: Style style = new Style();
style.ForeColor = System.Drawing.Color.Navy;
style.BackColor = System.Drawing.Color.LightGray;
this.Header.StyleSheet.CreateStyleRule(style, null, "body");
2. 链接外部的CSS样式表: HtmlLink link = new HtmlLink();
link.Attributes.Add("type", "text/css");
link.Attributes.Add("rel", "stylesheet");
link.Attributes.Add("href", "~/newstyle.css");
this.Header.Controls.Add(link);
方法3 aa.aspx.cs public string m_StyleSrc = string.Empty; //公共变量 ,样式文件路径
private void Page_Load(object sender, System.EventArgs e) {
m_StyleSrc = "../xxx.css"; //页面加载时赋值 }
}
aa.aspx <LINK href="<%=m_StyleSrc%>" type="text/css" rel="stylesheet">
方法4 下面这个方法没试过,不知是否能用
protected void Page_Onload(object sender, EventArgs e) {
Page.StyleSheetTheme = "../css/infomore.css";
}
方法5 页面：
<link href="" rel="stylesheet" type="text/css" id="css" runat="server"/>
后台
this.css.Href = "css文件路径";
