VB .NET doesn't have control arrays so I presume you're using VB 6. There a control array has LBound and UBound properties that give its lower and upper bounds. For example, this code loops through the text box array named txtData:
For i = txtData.LBound To txtData.UBound
txtData.Text = ""
Next i
If the array might be missing elements (i.e. you deleted one), see:

Ha, im sorry, my actual code is
dim lbl as label
do while ctr < 10
lbl=new label
lbl.setbounds(x...)
me.addcontrols(lbl)
loop
' i actually want to remove the 10 instances of the label.
I try me.removecontrols, but i only remove it the added controls and not the instances.
so please

How about:
For i As Integer = Me.Controls.Count - 1 To 0 Step -1
If TypeOf Me.Controls(i) Is Label Then
Me.Controls.RemoveAt(i)
End If
Next
