Hi,

I have a webservice with a webmethod that accepts two parameters
defined as
<WebMethod()> _
Public Function GetData(ByVal strID As String, _
ByVal ParamArray Params As String()) As
Xml.XmlNode


When this web service is consumed in front end, the proxy class
generates a signature that looks something like this

Public Function GetData(ByVal strID As String, ByVal Params()
As String) As System.Xml.XmlNode


If you notice the keyword 'ParamArray' is missing. Now when I send
multiple parameters all is fine. That is if the call looks something
like this

Arr(0) = "Test"
xmlData = GetData("SOME_STRING", Arr)

The code goes through fine. But if I try something like this

Arr(0) = "Test"
xmlData = GetData("SOME_STRING") ' with the second paramArray
parameter missing

then I get compilation error. This is because the signature of the
calling function does not match with that of the proxy generated for
the consumer app. But if I change the signature of the proxy function
explictly to something like this

Public Function GetData(ByVal strID As String, ByVal ParamArray Params
As String()) As System.Xml.XmlNode

Then it works.

What can I do to ensure that the proxy is correctly generated from the
webmethod signature for ParamArray cases?

Would appreciate some insights into the matter.

Thanks
Ritu

There is no such thing as ParamArray in web services!

Consider that web services are meant to be cross-platform. Many (if not
most) platforms don't have the concept of "paramarray".
