动态加载CSS文件

方法一:

<HEAD>

<title>WebForm1</title>

</HEAD>

private void Button1_Click(object sender, System.EventArgs e)

{Page.RegisterStartupScript("css",@"<script>mycss.styleSheet.addImport(\'stylesheet1.css\')</script>");

}

方法二:--- 戏子的方法..嘻..抄来的...

<HEAD>

<title>WebForm1</title>

<asp:placeholder id="myplaceholder" runat="server"></asp:placeholder>

</HEAD>

private void Button2_Click(object sender, System.EventArgs e)

{

System.Web.UI.Control a = Page.FindControl("myplaceholder");

System.Web.UI.HtmlControls.HtmlGenericControl objLink = new HtmlGenericControl("LINK");

objLink.Attributes.Add("rel","stylesheet");

objLink.Attributes.Add("type","text/css");

objLink.Attributes.Add("href","StyleSheet1.css");

objLink=objLink;

a.Controls.Add(objLink);

}

[注] asp:placeholder 这是控件是主要是起"占位符的做用"
