From Json.NET documentation:
http://james.newtonking.com/projects/json/help/?topic=html/ConvertingJSONandXML.htm
You can force a node to be rendered as an Array by adding the attribute json:Array='true'
to the XML node you are converting to JSON. Also, you need to declare the json prefix namespace at the XML header xmlns:json='http://james.newtonking.com/projects/json'
or else you will get an XML error stating that the json prefix is not declared.
The next example is provided by the documentation:
xml = @"<person xmlns:json='http://james.newtonking.com/projects/json' id='1'>
<name>Alan</name>
<url>http://www.google.com</url>
<role json:Array='true'>Admin</role>
</person>";
Generated output:
{
"person": {
"@id": "1",
"name": "Alan",
"url": "http://www.google.com",
"role": [
"Admin"
]
}
}
