Too many arguments to '' in VB.net - vb.net

Question

I'm trying to save from list field that have more than one data on it, how to save all of it at once?
I've try this code
Dim detail As New Detail
Dim detailBr As New DetailBridge
Dim i As Integer
For i = 0 To lstProduct.Items.Count - 1
detail = detailBr.Insert(Convert.ToInt32(ddlGroup.SelectedValue), lstProduct.Items(i).Value) 'error was here
Next
but I got an error in lstProduct.Items(i).Value the error said
Too many arguments to '...'
I'm not sure what the error is.
can anyone help? Thanks for advice.
UPDATE : detailBr is class and the code is
Public Function Insert(ByVal GroupID As Integer, ByVal ProductID As String) As Boolean
Dim iResult As Integer
Dim arrColumn() As String = {"GroupID", "ProductID"}
Dim arrValue() As Object = {GroupID, ProductID}
oConn.Open()
Dim SQLString As String = GenInsert("DetailGroup", arrColumn, arrValue)
Try
iResult = SCommand.Execute(SQLString, oConn)
Catch ex As Exception
Throw ex
Finally
oConn.Close()
End Try
If iResult > 0 Then
Return True
Else
Return False
End If
End Function

The problem here is with the GenInsert Function. Its last two arguments are arrays.
Dim arrColumn() As String = {"GroupID", "ProductID"}
Dim arrValue() As Object = {GroupID, ProductID}
Dim SQLString As String = GenInsert("DetailGroup", arrColumn, arrValue)
A procedure can define only one parameter array, and it must be the last parameter in the procedure definition. MSDN
In simple words you can have only one parameter as array in GenInsert function either arrColumn or arrValue
However, to solve your current problem you can use two dimensional array as parameter as in passing-two-dimensional-array-through-functions and MSDN: Arrays as Return Values and Parameters
