[RESOLVED] ArrayList - Passed over a web service

I'm writing a simple little web service.

Here are two functions from it:

VB Code:

<WebMethod()> _
    Public Function addTwoNums(ByVal numOne As Integer, ByVal numTwo As Integer) As Long
        addTwoNums = numOne + numTwo
        Return addTwoNums
    End Function
 
    <WebMethod()> _
    Public Function yadda() As ArrayList
        yadda = New ArrayList
        Dim str As String
        str = "one"
        yadda.Add(str)
        str = "two"
        yadda.Add(str)
        Return yadda
    End Function

On the other end I can use the addTwoNums() function fine.
But when I want to get the ArrayList from the service, I get an errors.
Here is the basic error.

Quote:

---

Error 1 Value of type '1-dimensional array of Object' cannot be converted to 'System.Collections.ArrayList'.

Here is my code to suck down the arrayList()

VB Code:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim result As ArrayList
        result = thisServ.yadda()
    End Sub

I guess the arrayList is converted to a system.object when it is being consumed?? Can I not cast it back into an arrayList so I can run through the items returned??

I've tried CType over and over to no avail. :(

I'm wanting to get a list of data from the web service with one function call rather than have to create a function for each element of the service.

If the ArrayList is indeed converted to an Object array then you can't cast it back. If you want an ArrayList you'd have to do something like this:

VB Code:

Dim result As New ArrayList
        result.AddRange(thisServ.yadda())

That was it. Perfect.

Thanks.
