I have software that was developed for me. It is ASP.NET which I have no experience with thus the development. This was delivered a long while ago. I need to make changes and am struggling.
This is a webservice with an api that you can call externally to retrieve data.
I am trying to figure out where the field order for export is specified.
A list of objects (records) is passed to the MediaTypeFormatter.WriteToStreamAsync method. Looking at method, I see no order specification.
Does the formatter just take the list of objects and output them using their properties as XML tags?
Any help greatly appreciated. A pointer to the (RTFM) fine manual would be helpful. I've googled but not found anything helpful.
Thanks.

Hi @Darryl Hoar,
A list of objects (records) is passed to the MediaTypeFormatter.WriteToStreamAsync method. Looking at method, I see no order specification.
Maybe you can combine your code to describe your problem.
What does order specification mean? You can take a look at the usage of MediaTypeFormatter.WriteToStreamAsync Method:
public virtual Task WriteToStreamAsync( Type type, object value, Stream writeStream, HttpContent content, TransportContext transportContext )
Does the formatter just take the list of objects and output them using their properties as XML tags?
It is also possible to return JSON. You can set the ResponseFormat.
The code generates and returns xml. It has a class defined (raweventrecord) with several properties (like public short? location {get;set;}. The class gets instantiated and populated with data from records in an sql server. When the software runs and a web query calls it, it returns xml data. Like <raweventrecord> <location>10</location> <raweventrecord> . Here's the question: Why does it not return xml data for all the properties of the raweventrecord class?
I'll see if I can sanitize some code to show.
thanks.
I figured it out. I have wasted bandwidth. It was returning all, but the generated xml has properties listed in alphabetical order. Sorry.
how can I mark your comment as accepted Lan ?
Hi @Darryl Hoar,
Glad you've solved it, I've turned my comment into an answer.
Hi @Darryl Hoar,
Why does it not return xml data for all the properties of the raweventrecord class?
You mean to return only some properties. You didn't provide the code and can only guess at the cause.
Service can't expose private/read-only properties.
Maybe you can try using <XmlElement>.
