Within a component we can use AuthorizeView but what is the equivalent when we need to check if user is authorized in code?

You can inject the AuthenticationStateProvider into a component as demonstrated in the docs.

This also works:

AuthenticationState can be used. Wrap the <Router> in a <CascadingAuthenticationState> component and do something like this in your component:

@code {
    [CascadingParameter]
    private Task<AuthenticationState> authStateTask {get; set;}

   protected override async Task OnInitializedAsync()
    {
        var authstate = await authStateTask;
        var someRole = authstate.User.Claims.Single(c => c.Type == "your_role").Value;

       //if role is OK do something....
    }
}
