You can add header links to CSS files in ASP.Net codebehind classes like this:

HtmlLink link = new HtmlLink();
link.Href = "Cases/EditStyles.css";
link.Attributes.Add("type", "text/css");
link.Attributes.Add("rel", "stylesheet");
this.Header.Controls.Add(link);

You can iterate through the header controls beforehand to see if it is already there. The example shown is from a Page_Load in one of my projects and is inside a conditional expression that only adds the EditStyles.css if the page is supposed to be in "Edit" mode.

For ClientScriptManager.RegisterClientScriptBlock and ClientScriptManager.RegisterClientScriptResource, they have equivalent functions for checking if they've already been registered (e.g., IsClientScriptrResourceRegistered).
