How to put a conditional-dynamic stylesheet in header ASP.net C#

I want to add this to my masterpage:




But I want the set the "clinicblue7.css" part in the c# code. I am currently adding other stylesheets dynamically using this method. How do I do a similar thing with the above referenced code.

System.Web.UI.HtmlControls.HtmlLink link = new HtmlLink();
        link.Attributes.Add("media", "screen and (min-device-width: 481px)");
        link.Href = "Css/" + value + ".css";
        link.Attributes.Add("type", "text/css");
        link.Attributes.Add("rel", "stylesheet");
        Page.Header.Controls.Add(link);

Use this concept (Please let me know how it is):

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Request.Browser.Browser == "IE")
{
System.Web.UI.HtmlControls.HtmlLink link = new HtmlLink();
link.Attributes.Add("media", "screen and (min-device-width: 481px)");
link.Href = "Css/" + value + ".css";
link.Attributes.Add("type", "text/css");
link.Attributes.Add("rel", "stylesheet");
Page.Header.Controls.Add(link);
}
}
}

Thanks, but I am just looking to use the code I referenced to see that the browser is Internet Explorer and to use a specified stylesheet that I will specify dynamically in the code behind. This will have no end user interaction.

You can't determine the client browser by using c# or vb.net.
You have to use client side scripts only.

Yeah, I don't want to use c# to determine the browser. I just want to dynamically specify what style sheet to use if that browser condition is met in the head section of html.

this:



is what I will be using but I need to change the name of the css based on other things happening.
