I use vb.net and datagridview.
I want to check the DataGridView.SelectedRows in main form first, then user will leave the DataGridView,
i will store the rows index in array and pass to option form. After user chick the option form (OptionForm.show) and do something.

But i also some of technology problem. I don't know how can pass an array to other form store it and define a unknow array to pass , store.
The below is not finish code.
Anyone can give some of idea to me.....Thank you~~~


Public Class MainForm
Public tempRowArray As ArrayList

Private Sub AccessrightDataGridView_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles AccessrightDataGridView.Leave
tempRowArray = New ArrayList
tempRowArray.Clear()
For Each r As DataGridViewRow In AccessrightDataGridView.SelectedRows
tempRowArray.Add(r.Index)
Next

OptionForm.AccessRightPassRowNo = tempRowArray.Count ' (error)my problem in this, i don't know how to pass the unknow array number in right method
OptionForm.AccessRightPassRowArray = tempRowArray '(error)my problem in this
End Sub

Private Sub BtnBatch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnBatch.Click
OptionForm.Show()
End Sub
