QUESTION
I am trying to create an abstraction layer for Json.NET deserialization using interfaces.
To achieve this I use custom JsonConverter
which works just fine, until interfaces are introduced.
Following exception is thrown:
Unhandled Exception: Newtonsoft.Json.JsonSerializationException: Error setting value to 'Items' on 'BatchList'. ---> System.InvalidCastException: Unable to cast object of type 'System.Collections.Generic.List1[BatchItems]' to type 'System.Collections.Generic.List`1[IBatchItems]
This is the setup to repro in a console app:
...ANSWER
Answered 2019-Apr-11 at 19:35What you need to do is to combine the functionality of the following two converters:
SingleOrArrayConverter
from this answer to How to handle both a single item and an array for the same property using JSON.net by Brian Rogers.This converter handles the frequently-encountered case where a one-item collection is not serialized as a collection; you are already using this converter.
ConcreteConverter
from this answer to How to deserialize collection of interfaces when concrete classes contains other interfaces.This converter deserializes a declared interface (here
IBatchItems
) into a specified concrete type (hereBatchItems
). This is required becauseIList
is not covariant and thus anIList
cannot be assigned to aIList
as you are currently trying to do.
The best way to combine these two converters is to adopt the decorator pattern and enhance SingleOrArrayConverter
to encapsulate a converter for each of the list's items inside the list converter:

Install jsonbatch
You can use jsonbatch like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the jsonbatch component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
