How to mark every point?

Good day,
a mathematical or logical question rather than a direct coding one. How do I write an extract from a worksheet where points are stored but with an unknown number?

List<MapPoint> lineMapPoints = new List<MapPoint>() {  //At this point, write some clever positioning };

I do not know if I explained it enough, if there were any ambiguities feel free to ask me :)

Thank you all for any advice

Improve:
I would like to list all the points from the list, even if I don't know their number. For example pts[0] we know that is the first point
pts[numPts - 1] indicates last

But I don´t know how to write other points whether you need 30 or just 2 in between

What I have tried:

List<MapPoint> lineMapPoints = new List<MapPoint>() {  pts[numPts/2], pts[numPts - 1] , pts[0] };

I have tried this but it is seriously insufficient to solve :D

numpts= number of points int
pts= points

Improve: My solution contains only the first, last and half point (but this is insufficient)

Not even close.
I have no idea at all what you are trying to achieve, much less what you have tried and why it didn't work.

Solution 1

If you want to add all points to your loop, you could just initialize your list and then add your points with AddRange. It would look something like this:

C#

List<MapPoint> lineMapPoints = new List<MapPoint>();
lineMapPoints.AddRange(pts);
