AutoCAD .NET :: Insert Block With Attributes In Existing Table

I'm creating a routine to fill in my terminal strips. This routine worked perfectly in Vba but I'm now rewriting it for .NET...The problem is that I want to insert a block with attributes into different cells.The tables already exists. Below my function, I'm stuck on this part

Dim lonReturnedIds = FunBlockId() ' Calls the function FunBlockID to get the ID's of the attributes
' 0 = BlockID
' 1 = AttributeID of KleurB
' 2 = AttributeID of KleurO
TS.Cells(i, intPosition).Contents.Add()
TS.Cells(i, intPosition).Contents(0).BlockTableRecordId = lonReturnedIds(0)
TS.Cells(i, intPosition).SetBlockAttributeValue(lonReturnedIds(1), strCableConductor2WriteFirst)

Public Function Fun_StripUp(ByVal Po3dXY As Point3d, ByVal str_CableName As String, ByVal Str_CableConductor As String, ByVal strCable Conductor 2 Write As String, ByVal strCableConductor2WriteFirst As String, ByVal intPosition As Integer) As StringDim tAcadDoc As ApplicationServices.Document = ApplicationServices.Application.DocumentManager.MdiActiveDocumentDim myDB As.
