Int Array from a SOAP SOE Response

[MeleKoneya]

I currently have a SOAP Server Object Extension that is returning a string.    The string is a pair of comma delimited coordinates, but what I really want to get back is an array of integers.

What I have is something like this (with business logic removed)

private string OffsetCoords(string StrName, int sp_x, int sp_y, string offsetDir, double offset)
{
return string
}

What I would like it to do is something like this

private int[] OffsetCoords(string StrName, int sp_x, int sp_y, string offsetDir, double offset)
{
return int[]
}

Writing the business logic is not a problem, but what I am not clear on is what to return from my method.    Does an integer array work in this case or is their a better type to use?

Also,  I am not clear on how to format the WSDL and the Imessage parameters to accept the data type returned by the method.   I have the WSDL configured to return a string with the following code:

<xs:element name="OffsetCoordsResponse">
        <xs:complexType>
          <xs:sequence>
            <xs:element name="NewXY" type="xs:string" />
          </xs:sequence>
        </xs:complexType>
      </xs:element>
     </xs:schema>

And my code containing the Imessage is below where respMsg implements Imessage.

string newCoords = OffsetCoords(StrName, sp_x, sp_y, offsetDir, offset);

//fill response
respMsg.Name = "OffsetCoordsResponse";                   
respMsg.NamespaceURI = c_ns_soe;                           
respMsg.Parameters.AddString("NewXY", newCoords);

Do I use AddObject to the Imessage.Parameters method and if so can you provide some structure?

Thanks,

Mele
