QuestionProblem deserialising JSON data [SOLVED by the brilliant Richard Deeming] Pin
Richard MacCutchan18-Jul-19 2:03
protectorRichard MacCutchan18-Jul-19 2:03 
I am struggling to deserialize a load of JSON as below (the relevant sections).

The problem is the last array titled volunteer_properties which the DataContractJsonSerializer seems to have a problem with. It appears to me to be an array of anonymous objects, each of which contains a named object which has a number of members. So my DataContract entries are trying to follow the same pattern. The array named "roles" is deserialized quite correctly. Note the deserializer recognises the array and creates it, but each object is null.

I have tried a number of different approaches, including naming the Propentry member corresponding to "first_name", etc, changing the type of the array, etc., all to no avail.

If anyone has a suggestion as to how to get past this I will be most grateful.
