pass an arry from c# to VBA

C dll code

namespace PassInts
{
public class changeInts
{

public int passInteger(int i)
{
return i + 11;
}

public int[] passArray(int[]i)
{
int[] k = new int [i.Length];

for (int ii = 0; ii < i.Length; ii++)
{
k[ii] =i[ii] + 11;
}
return k;
}
}
}

vb form code

Imports PassInts
Public Class Form1
Public passInts As New changeInts

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer = passInts.passInteger(5)
ListBox1.Items.Clear()
ListBox1.Items.Add(i)
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim k() As Integer = {5, 4, 2, 3, 7}
Dim i() As Integer = passInts.passArray(k)
ListBox1.Items.Clear()
For Each j As Integer In i
ListBox1.Items.Add(j)
Next
End Sub
End Class

Thanks,

this was my first ideas too,
but this doesn't work either, so I tried to pass it as a reference parameter.

Dim i() as Integer ' i has to be an array
Dim a() as Integer

i =  csharp.passArray ( a() )
