C# / Delphi – getting the right parameter and function result order for SOAP

Posted by jpluimers on 2010/01/05

Getting different architectures to talk can be a pain, even when using standards like SOAP.

In this case, the .NET WSDL imports Delphi generated WSDL in a different manner than you’d expect at first sight: when having both an ‘out’ parameter and a function ‘result’, the ‘result’ is not imported well.

But alas: SOAP didn’t accommodate for this situation in the past, and now SOAP now has some additions to solve this.

Bruneau Babet explains this here: [WayBackSOAP inconsistency? Delphi 2010 (Win32) Server and .NET Client swapping ‘out-parameter’ and ‘result’. – Stack Overflow.

There he explains how to use the parameterOrder attribute, which the Delphi WSDL importer and exporter still do not support.
