Von VBA in C#

Kann mir bitte jemand beim Umformen des Codes von VBA in C# helfen?

Sub subAuslesen(NodX As node)
Dim NodItem As node

i = 0

    Do Until NodX Is Nothing
            i = i + 1
            m = (i * 10)
            'strPosNummer = funIntPosnummer(Left(NodX, 6))
            subDatenEintragen NodX.Parent.Text, NodX.Text, m

            If NodX.Child Is Nothing Then
            Else
                Set NodItem = NodX.Child

                Do Until NodItem Is Nothing
                    m = m + 1
                    subDatenEintragen NodItem.Parent.Text, NodItem.Text, m
                    Set NodItem = NodItem.Next
                Loop
            End If
        Set NodX = NodX.Next
    Loop

End Sub

Private Sub subEbeneErstellen()
    Dim rsa As ADODB.Recordset
    Dim strKey, strKeyParent, strText As String

    Set cnn = CurrentProject.Connection
    Set rsa = New Recordset
    Set F = Me

    strSQL = strSQLBauen(Me.txtBaugruppe)
    rsa.Open strSQL, cnn, adOpenDynamic, adLockReadOnly

    Set nod = F.treStueLi.Nodes.Add(, , "a" & Me.txtBaugruppe, Me.txtBaugruppe)
    nod.Expanded = True
    Do Until rsa.EOF
        If Left(rsa!ident, 1) = "5" Then
            m = m + 1
            strKey = "b_" & m & "_" & rsa!ident
            strKeyParent = "a" & Me.txtBaugruppe
            strText = rsa!ident & " " & rsa!Ben1 & " ~ " & rsa!Count
            Set nod = F.treStueLi.Nodes.Add(strKeyParent, tvwChild, strKey, strText)
        End If
        rsa.MoveNext
    Loop
    rsa.Close
    cnn.Close
    Set rsa = Nothing
End Sub

Auch habe ich ein Problem damit, wie ich folgendes initialisieren soll:

Dim nod As MSComctlLib.node
Dim F As Form
