I’m creating a .net app that manages some feeds from various web services. I’ve just started using JSON.NET and I’m looking to do all my conversion to my .net objects from JSON.

So, I thought for any feed that I can’t get as JSON, I’d get the XML and convert it first to JSON, then I could use a single set of methods that process the JSON to do the actual work.

In doing this, I’ve encountered the following problem: after converting the XML to a JSON string (called myInput) with JsonConvert.SerializeXmlNode(myXMLdoc), I get an error when using JsonConvert.DeserializeObject(Of List(Of Object))(myInput):

Cannot deserialize JSON object into type
‘System.Collections.Generic.List`1[System.Object]’. Line 1, position
8.

myInput starts like this:

{"?xml":{"@version":"1.0","@encoding":"UTF-8","@standalone":"yes"},"items":{"@size":"72","item":[{"id":"123456","description": ...

So, my question is specifically what is causing this error, but I’d be happy also to hear whether generally my approach is a good idea (i.e. converting all my input data to JSON before proceeding) – or if there’s an established pattern for doing this sort of thing that I would be better learning about and implementing.

    I think that the problem is with wrong formatting of your JSON string.

    Deserialization is complaining that you can’t deserialize a JSON object into a List.

    {} – means JSON object = .NET object with properties on it or .NET dictionary

    [] – means JSON array = .NET array or list

    So you should extract only items from the json string and store them as a ‘[]’
