Compile-time tree structure

Question

I want to get values ​​from a tree stored in another system. For instance:

GetValue("Vehicle.Car.Ford.Focus.Engine.Oil.Color")

To avoid entering errors and invalid keys, I want to check the name at compile time by creating an object or class with a tree structure in it:

GetValue(Vehicle.Car.Ford.Focus.Engine.Oil.Color)

Is there an easy way to do this in C # without creating classes for each node tree? Can I use anonymous classes or subclasses? Should I automatically generate code?

                        public static readonly string Color =

    {
         public static readonly string Color =

Answer 3

Try the following:

var Vehicle = new { Car = new { Ford = new { Focus = new { Engine = new { Oil = new {Color = "Red"}}}}}};

Now you can get each value with intellisence.

Although I prefer the @dtb approach. However, I think my approach is pretty easy.

You might find a way to do this using the C # extension methods: http://msdn.microsoft.com/en-us/library/bb383977.aspx

But there is probably no way out of any automatic code generation
