How can Json.NET perform dependency injection during deserialization?

Question

When I have a class with no default constructor, i.e. using dependency injection to pass its dependencies, can Newtonsoft.Json create such an object?

Answer 1

If your objective is to use the injected dependency to modify the data, then you can create a custom Converter.

With this, you should be able to inject your dependency. Similar to the code below:

 var settings = new JsonSerializerSettings
            {
                Converters = { new FooConverter(injectedDependency) }
            };
 return JsonConvert.DeserializeObject(json, settings);

There're many samples of how to create a custom Converters, so you can refer to them.
