C# get object type

Like in gdscript the result of a raycast is a dictionary.
But is there a more elegant way to check if the hit object is of certain type?
Using "is" to check the type or GetType() always returns Godot.Variant

Character is the class inherited from CharacterBody3D.

This works, but I really don't like it. :/

        if (raycastResult.TryGetValue("collider", out var colliderVariant))
        {

            var collider = colliderVariant.AsGodotObject() as Character;

            if (collider != null)
            {
                GD.Print("Char");
            }
            else
            {
                GD.Print("Collider is not a Character, it's a " + colliderVariant.GetType());
            }
        }
