c#_DataTree_alternate selection of Objects

Hello,
I have divided the curves by length factor. I want to select the output points alternatively. I am able to sort them alternatively using DataTree. Since all the branch item counts are not same, last few points I am not able to select.
Any help in this regard would be great!

ps.1) I am pretty new to c# and trying out data tree in c# for the first time. I would like to know more about it, if there is any material out on this please let me know.

    DataTree < Point3d > pD1 = new DataTree();
    DataTree < Point3d > fD1 = new DataTree();

// bC1 is list of curves

for(int k = 0; k < bC1.Count; k++)
{
  Point3d[] p1;
  bC1[k].DivideByLength(0.5, true, out p1);
  GH_Path gP1 = new GH_Path(k); 
  pD1.AddRange(p1, gP1);
}
for(int l = 0; l < pD1.BranchCount; l++)
{
  for(int m = 0;m < pD1.Branch(3).Count;m += 2)
  {
    GH_Path gF1 = new GH_Path(l); 
    fD1.Add(pD1.Branch(l)[m], gF1);
  }
}

B = pD1;
C = fD1;
