Grasshopper VB Component Path and Item Access

Hi Folks,

I know this has to be super easy, but it's been eluding me...I have a long list of strings in grasshopper in the following (shortened) structure:

{0}

  (0) x.xxxx, y.yyyy

  (1) x.xxxx, y.yyyy

  (2) x.xxxx, y.yyyy

{1}

  (0) x.xxxx, y.yyyy

  (1) x.xxxx, y.yyyy

  (2) x.xxxx, y.yyyy

I would like to use a VB script component to spit out a list of strings in the following format so I can save them in a CSV file:

0, x.xxxx, y.yyyy

0, x.xxxx, y.yyyy

0, x.xxxx, y.yyyy

1, x.xxxx, y.yyyy

1, x.xxxx, y.yyyy

1, x.xxxx, y.yyyy

I've searched around the discussion board and found the following code snippet:

Private Sub RunScript(ByVal x As DataTree(Of Object), ByVal y As DataTree(Of Object), ByRef A As Object)
    Dim zones As New List(Of String)
    Dim table As New List(Of Int32)
    For i As Int32 = 0 To x.BranchCount - 1
      Dim path As Grasshopper.Kernel.Data.GH_Path = x.path(i)
      If (table.Contains(path(0))) Then Continue For
      table.Add(path(0))
      For j As Int32 = 0 To x.DataCount 'DataCount returns all items in tree?!
        zones.Add(path(0).ToString())
      Next
    Next
    A = zones
  End Sub

I modified it a bit by nesting another for-next loop to spit out the repeating path index. I was hoping that x.DataCount would return the number of items in that particular path, but it appears to return the total number of items in the tree.

The question: How do I return the number of individual entities in a particular path?

Is there a simpler way, perhaps without scripting?

And, in general, where's a good go-to to find a list of GH classes and their methods as well as explanations. If I saw it all in one place, it might be easier for me to understand how this is all structured, rather than seeing little bits here and there...

Thanks!
