ASP.NET - path to use to reference .CSS and .JS

Question

I have a Master Page in the root of my project. I have Content Pages throughout my project and in subfolders referencing this Master Page. What is the correct way to reference my .CSS and .JS files if I always want them to be relative to the root?

Here is how I'm doing it now:

link href="/common/css/global.css"
script src="/common/javascript/global.js"

But that breaks the link. I tried without the leading "/" but that didn't work on my pages in the subfolders.

Answer 1

I would use something like

Server.ResolveClientUrl("~/common/css/global.css")

This will get a proper url for you at all times.

Example:

Per the comment this would be full usage.

<link type="text/css" rel="stylesheet" 
    href='<%= Server.ResolveClientUrl("~/common/css/global.css") %>' />

According to comments, other validated usage, no "error CS1061: 'System.Web.HttpServerUtility' does not contain a definition" error:

    <script type="text/javascript" 
src="<%= Page.ResolveUrl("~/Scripts/YourScript.js") %>" ></script>

Also is important to always put the closing tag .
