Shortest route between multiple points

Question

I need to find the shortest route between multipe points. Let\'s say that I have these four points:

var startPoint = new Point(1, 1);
var pointsToGoPast = new Li         


        

Answer 1

Can be solved simply if you have SQL server

select geography :: Point(@PointALatitude, @PointALongitude, 4326).STDistance(geography::Point(@PointBLatitude, @PointBLongitude, 4326))

Result is returned in meters so just divide by 1000 for Km or 1609.344 for Miles
