Stephen,
Have you checked the sample code at http://developers.marketo.com/documentation/soap/getmultipleleads/? The Java version shows how to use the static list selector. We will be adding C# samples soon, but in the meantime, feel free to log a support ticket if you are unable to get this to work.

ObjectFactory objectFactory = new ObjectFactory();

JAXBElement<String> listName = objectFactory.createStaticListSelectorStaticListName("SMSProgram.listForTesting");

staticListSelector.setStaticListName(listName);
