Get root directory razor page

Question

I built html helper to change class attribute based on current page. When using MVC, I can get the value for Controller and Action by using this method

string actualAction = (string) html.ViewContext.RouteData.Values["action"];
string actualController = (string) html.ViewContext.RouteData.Values["controller"];

Using razor pages , I can get the razor page endpoint by using this code

var rv = html.ViewContext.RouteData.Values;

string page = $"{rv["page"]}".ToLowerInvariant();

So I will get the value such like /admin/dashboard , /admin/configuration/add-user , /admin/configuration/list-user and etc.

At the endpoint, I want to know what is the first directory name. Following my example, the admin is a root directory.

Is there is a .Net core function handles this? or need to customize?

You can use the HttpContext . Check here on how to access it, depending where you are: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/http-context?view=aspnetcore-3.1

Then access the path from the context request:

Context.Request.Path

To use it from the view

@{
    var path = Context.Request.Path;
    ...
}
