Question

I’m trying to pass an array of object to my web service.

var bookingResponse = Service.BookOrder(
    User, Password, Header, order.ToArray(), 1,
    order.OrderId, order.CalculatedID(SessionRO));

On the Service:

public orderreturn BookOrder(
    string username, string password, OrderHeader order,
    OrderDetail[] order, int extSystemID, int extOrderID, int eventID)

Although order has data on the sending side it is coming back as null/empty on the receiving side. Any suggestions?

For arrays of custom types to pass you need to mark them with [DataContract] and the properties with [DataMember].

This might get you started;
