JSON Deserialization with an array of polymorphic objects

Question

I\'m having a problem with JSON Deserialization involving an array of polymorphic objects. I\'ve tried the solutions for serialization documented here and here which work great

Answer 1

You have not added any settings upon deserialization. You need to apply settings with TypeNameHandling set to Object or All.

Like this:

JsonConvert.DeserializeObject(
    returnedStringFromClient, 
    typeof(Scoresheet), 
    new JsonSerializerSettings 
    { 
        TypeNameHandling = TypeNameHandling.Objects 
    });
