I’m using a third part web service[WS] in my .Net app.
My application is using the entity classes generated from this WS’s wsdl.
I fetch the data from db, fill it in entity objects and then generate an xml out of it using XmlSerializer class.
One of the methods of the WS requires this xml string as input.And the xml should have elements in the same order as expected by the WS.But whats happening is that some of the elements are getting upside down in my app and so WS is throwing an innermost exception saying on serialzation:.
_innerException {“Inconsistent sequencing: if used on one of the class’s members, the ‘Order’ property is required on all particle-like members, please explicitly set ‘Order’ using XmlElement, XmlAnyElement or XmlArray custom attribute on class member ‘instrument’.”} System.Exception {System.InvalidOperationException}
XmlSerializer serializer = new XmlSerializer(typeof(totemmessage));
So,my question here is, how do I programmatically control the order of these xml elements in my app before sending it to the WS?Note:I dont want to use xslt for this purpose.
Thanks for reading.
Here are my entity classes:

I used XmlElement[Order =n] on top of each of the properties in the entity classes. So, after playing around with the ordering, I could made this serialization work.Inheritance and partial classes made this fix all the more difficult!Thanks.
