Question

I have a list of points which I am using to add points.

I have two approaches but I just want to know which one is better.

Following is the code for first approach:

 List<Point> borderPoints = new List<Point>();

                Point p1 = new Point(0, 0);
                Point p2 = new Point(Width, 0);

                borderPoints.AddRange(new[] { p1, p2 });

in the second approach I add the points like below:

 borderPoints.Add(p1);
 borderPoints.Add(p2);

I have to add the points four times, so which approach I should follow and why, or it doesn’t matter, it’s just the case of style ?

Answer 1

You are right.
In your situation it is more a case of your programming style.

Add() is simple and convenient in cycles while
AddRange() looks more elegant when used at once.

Thinking about performance:

AddRange() adds an array of previously created tree nodes to the collection while Add() adds a new tree node to the collection (MSDN documentation).

So if you are only adding just 4 of nodes or adding nodes infrequently, use the Add().
