Here's a link that shows how to get Rhinoscript through a VB.net plugin.  I imagine this could be modified to work from the GH script component.

Yeah ,Cool!

But I still have two question,one is what the algorithm of the SurfaceCurvatureAnalysis Function?And how to get use Rhinoscript from .Net plugin  in Rhino 5?

I've been looking at the code for this, but I'm not great at reading C++. It seems to me though that the algorithm is nothing more advanced than creating an analysis mesh for the surface (or using the one that already exists) and then just finding the highest and lowest curvature of all mesh vertices. Analysis meshes in Rhino store curvature data.

 

This basically amounts to just sampling the curvature a lot and then finding the extreme samples.

Here's another link from the developer page.  The code is C# but it shows the method.
