Method called by asp.net to dynamically add style sheets in the back end

This article shows an example of how asp.net dynamically adds style sheet calls in the back end.Share it for your reference.The implementation is as follows:

HtmlLink CssControl = new HtmlLink();
CssControl.Href = url;
CssControl.Attributes.Add("rel", "stylesheet");
CssControl.Attributes.Add("type", "text/css");
page.Header.Controls.Add(CssControl);

I hope that the description in this paper will be helpful to everyone's asp.net program design.
