<LINK rel="stylesheet" type="text/css" href="" id="mycss">
</HEAD>

private void Button1_Click(object sender, System.EventArgs e)
        {Page.RegisterStartupScript("css",@"<script>mycss.styleSheet.addImport('stylesheet1.css')</script>");
        } 

方法二:--- 戲子的方法..嘻..抄來的...<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  這是控制項是主要是起"預留位置的做用"
