Divide surface and find the curvature underneath every single point

Hello…

I am working on the project. I want to divide the surface and find curvature underneath of every single point on the surface. I know interrelations (c# script) would be needed in this task.

I have tried following step..

1.Divide the surface in small parts(UV points)

2.Get the isocurves

3.In c#script

    3.1 get each isocurve (U ISO or V ISO)

    3.2 get the curvature at every small step on the isocurve (but don’t how to find curvature in c# script)

Can somebody guide me (especially in script part) or correct me or share his/her ideas?

I am new to grasshopper.

Thanks in advance.
