index was out of bounds error in vb.net script

Question

I am having the index was out of bounds error for the following script. I have 1 input column and 11 output columns added to the SSIS Script component. The data types for all of them are string. Not sure where I am going wrong. Thanks in Advance.

Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
    Dim strRow As String
    Dim strColSeperator As String
    Dim rowValues As String()
    strRow = Row.Line.ToString()
    If strRow.Contains("-") Then
        strColSeperator = ("-")
    ElseIf strRow.Contains(";") Then
        strColSeperator = ";"
    End If

    rowValues = Row.Line.Split(CChar(strColSeperator))
    Row.Invoices = rowValues.GetValue(0).ToString()
    Row.Detail = rowValues.GetValue(1).ToString()
    Row.Date = rowValues.GetValue(2).ToString()
    Row.Something1 = rowValues.GetValue(3).ToString()
    Row.Something2 = rowValues.GetValue(4).ToString()
    Row.SomeNumber = rowValues.GetValue(5).ToString()
    Row.CustomerName = rowValues.GetValue(6).ToString()
    Row.InvoiceNumber = rowValues.GetValue(7).ToString()
    Row.InvoiceNumber2 = rowValues.GetValue(8).ToString()
    Row.InvoiceNumber3 = rowValues.GetValue(9).ToString()
    Row.InvoiceNumber4 = rowValues.GetValue(10).ToString()

End Sub

Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer) 
    Dim strRow As String 
    Dim strColSeperator As Char ' <== Char instead of string 
    Dim rowValues As String() 

    strRow = Row.Line.ToString() 
    If strRow.Contains("-") Then 
        strColSeperator = "-"c ' <== the 'c' denotes a Char literal
    ElseIf strRow.Contains(";") Then 
        strColSeperator = ";"c 
    End If 

    rowValues = strRow.Split(strColSeperator) ' <== Now CChar is obsolete
    MsgBox("rowValues length = " & rowValues.Length) ' <== Check to see if it's really as long as expected!
    Row.Invoices = rowValues(0) ' <== Use the array indexer instead of GetValue and ToString
    Row.Detail = rowValues(1) 
    Row.Date = rowValues(2) 
    Row.Something1 = rowValues(3)
    Row.Something2 = rowValues(4)
    Row.SomeNumber = rowValues(5)
    Row.CustomerName = rowValues(6)
    Row.InvoiceNumber = rowValues(7)
    Row.InvoiceNumber2 = rowValues(8)
    Row.InvoiceNumber3 = rowValues(9)
    Row.InvoiceNumber4 = rowValues(10)
End Sub
