Predicate to search a List<List<Point>>?

[Insider1984]

Hi there. I have a List<List<Point>> (maybe this is a bad idea but i need 2D array with speed).

The problem I have is search for points inside this array. I know that I should use a Predicate but the only example I found (interestingly enough) is from Microsoft and they are using an Array[] Points.

I think I'm very close but need help with one peice of code inside the predicate, the P coming in.... is that the point from my list of lists or is it the point that I'm trying to find on?

How do I do the comparison? Also see if their is a way below to make this easier.....

                            Nullable<Point> temppoint = new Nullable<Point>(new Nullable<Point>(new Point(pointX - 1, pointY)));
                            int temp = tempDefectBlob[tempDefectBlob.Count].Find(temppoint,PointMatch);



//later in the code:
    private static bool PointMatch(Point p)
    {
        if (p.X == ?????? %% p.Y == ???????)
        {
            return true;
        }
        else
        {
            return false;
        }
    }

Should I use a List<Point[]> instead?

Well, for the outer most List, item type is List<Point>, so you need to search for List, not Point. I presume that the code should look something like this:

List<List<Point>>   points;

foreach (List<Point> list in points)
{
    if (list.find(test_point))
        return true;
}
return false;

When you do it, do it right.
