c# ToList question

Hi all,

I have a simple problem:

I want to get the .Min and .Max value of various lists. I Already get the value but one for every list but I would just need one value out of all.

Same as flatten the bounds component in GH. I think .ToList is the right way but dont get it to work.

I think I could get the value using a tree instead of a list and flatten the tree,but maybe I am totally wrong and someone can offer a nicer and claener way to reach this.

Ah, and yes flattening the points input would surely work but for the sake of learning it would be nice see another way

thanks in advance!

Using tree access is one way to go (I think the best way).

private void RunScript(DataTree<Point3d> pts, Curve crv, Interval Target, ref object A, ref object B, ref object C)
{
Component.Message = "CrvClosestPt";

double min = double.MaxValue;
double max = double.MinValue;
List<double> distances = new List<double>();

foreach (Point3d point in pts.AllData())
{
double parameter;
crv.ClosestPoint(point, out parameter);
Point3d cp = crv.PointAt(parameter);
double localDistance = cp.DistanceTo(point);

distances.Add(localDistance);
min = Math.Min(min, localDistance);
max = Math.Max(max, localDistance);
}

A = distances;
B = min;
C = max;
}
