this can be done using the below method in the page load method of the site.

HtmlLink subcss = new HtmlLink();
        subcss.Href = name of css file as sting;
        subcss.Attributes.Add("rel", "stylesheet");
        subcss.Attributes.Add("type", "text/css");
        Page.Header.Controls.Add(subcss);
