Combining CSS files depending on the request domain?

Question

I have an application with several tenants, and I'm trying to determine the simplest ways to manage CSS files depending on the URL of any incoming request.

I think I can have some conditional logic inside RegisterBundles () that takes Url as a string and binds accordingly:

public static void RegisterBundles(BundleCollection bundles, string tenant = null) {
     if (tenant == "contoso"){
           bundles.Add(new StyleBundle("~/contoso.css") 
     }
}

But I do not know how to pass a string to RegisterBundles, even if it is possible, or the correct solution. Any help here would be amazing.

Answer 1

RegisterBundles . ASP.net -CSS ( HttpContext.Cache).

, RegisterBundles, .

:

@Styles.Render("~/Content/" + ViewBag.TenantName)

Edit:

, TenantName ViewBag , . - Styles.Render(), , .

public static class TenantStyles
{
    public static IHtmlString Render(params string[] paths)
    {
        var tenantName = "test"; //get tenant name from where its currently stored
        var tenantExtension = "-" + tenantName;
        return Styles.Render(paths.Select(i => i + tenantExtension).ToArray());
    }
}

@TenantStyles.Render("~/Content/css")

{bundle} - {tenant}, ~/Content/css-test. .
