How to pass a structure/array of structure as input parameter in a webservice

Question

Hi Team,
I am trying to create a webservice in powerbuilder .net( pb 12.5.1) . As this webservice will be used by external world to access some of data on basis of some input paarameter.
So can i use array of structure as input parameter to a webservice ? If no, then how can i pass a result set ( mora then 1 row with more than one column)
as an argument to the webservice.

I am assuming this is the same for .Net but in Classic you can create NVO's with Instance Variables and then reference them in the NVO that will be used as the parameter for the Public WebService.
WS NVO's:
Children
     String             Child[]
Customer
     String             FirstName
     String             LastName
     String             DOB
     Children          Children
Public Interface uses Customer
Calling Code Example:
integer    rc, liNdx
string     lsReturn
SoapConnection lSoapConnect
proxy_testing  px_Testing
lSoapConnect = CREATE SoapConnection
if IsValid(lSoapConnect) then
TRY
  rc = lSoapConnect.CreateInstance(px_Testing, 'proxy_testing')
  CHOOSE CASE rc
   CASE 100
    lsReturn = "Invalid proxy name"
   CASE 101
    lsReturn = "Failed to create proxy"
   CASE 0
    Proxy_Customer lNewCustomer
    lNewCustomer = CREATE Proxy_Customer
    lNewCustomer.FirstName = 'Chris'
    lNewCustomer.LastName = 'Craft'
    lNewCustomer.DOB = 'Getting Older'
    Proxy_Children lChildren
    lChildren = CREATE Proxy_Children
    lChildren.Child[1] = 'Madeline'
    lChildren.Child[2] = 'Hayden'
    lNewCustomer.Children = lChildren
    lsReturn = px_Testing.NewCustomer(lNewCustomer)
   CASE ELSE
    lsReturn = "Unknown error (" + String(rc) + ")"
  END CHOOSE
  if rc <> 0 then MessageBox("Invocation Error", lsReturn, Exclamation!)
CATCH (RuntimeError rte)
  rc = -1
  MessageBox("Runtime Error", rte.text, Exclamation!)
END TRY
end if
