c++ or c# class opening

Question

I used to write:

window.size.X=19;
window.size.Y=39;
window.location.X=29;
window.location.Y=79;

But it would be much easier to open class before modyfing it like:

window{
    size{
        X=19;
        Y=39;
    }
    location{
        X=29;
        Y=79;
    }
}

That would reduce code size ,it would read more easily and clearly
and take much less disc space.
Words are not repeating that many times.

Is class opening like one in example above possible in c++ or c#?
Is there any language that would allow class opening?

Answer 1

I dont think you can use that exact syntax but you could do something like this in C#. I used the WPF window class not exactly the same as yours

        Window window = new Window()
        {
            RenderSize = new Size()
            {
                Height = 100,
                Width = 200
            },
            WindowStartupLocation = WindowStartupLocation.CenterScreen
        };
