Create ASP.NET VB Web Service with Array

Hi all, I'm new at the web service development thing...and hopefully someone can help me design a basic web service that does the following:

Receives three pieces of data:

- OrderID (Int32)
- OrderStatus (String, 1)
- OrderDate (DateTime)

Now, if the client was connecting to the web service and giving me one record at a time with a response, it would be a no-brainer on how to create this...

Basically, what I need to do is accept multiple records at once...Is an array the best way to accept?

Then, if all succeeds, I send them back a message or code that says the import was successful.  If it failed, (or a record or two failed), I send them back an array or something that tells them which orders failed to be accepted.

Any code examples in VB would be greatly appreciated.

<WebMethod()> _
    Public Function ImportOrders(ByVal orderid As Integer()) As Integer()
        Dim failed As Integer()
        Dim i As Integer, k As Integer

        k = 0
        For i = 0 To orderid.Length - 1
            If orderid(i) < 1 Or orderid(i) > 10 Then
                ReDim failed(k + 1)
                failed(k) = orderid(i)
            End If
        Next
        Return failed
    End Function

Add a web form and add the following code on page load event

Dim obj As New Service1
        Dim orderids As Integer() = {2, 11, 1, 10}
        Dim failed As Integer()
        failed = obj.ImportOrders(orderids)

        Dim i As Integer
        For i = 0 To failed.Length - 1
            Response.Write(failed(i).ToString() + "<br>")
        Next
