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.

add following function into service1.asmx file

<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
        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>")
