Calculating the distance between 2 points in c#

Question

I am trying to sort out a method to calculate the distance between 2 points in c#.

This is the code I have been trying though I fear the answer I get is not correct.

Answer 1

You can use DbGeography for spatial calculation. It has DbGeography.Distance method which is used to calculate the distance between two gps points.

Otherwise, try Ref: Harversine Formula to calculate the distance between two points.
