Json.net serialization of custom collection implementing IEnumerable

As of Json.NET 6.0 Release 3 and later (I tested on 8.0.3), this works automatically as long as the custom class implementing IEnumerable<MyType> has a constructor that takes an IEnumerable<MyType> input argument.

Jackson deserialize based on type

context in nested serializers django rest framework

Ok i found a working solution. I replaced the ChildSerializer assignment in the Parent class with a SerializerMethodField which adds the context. This is then passed to the get_fields method in my CustomModelSerializer: class ChildSerializer(CustomModelSerializer): class Meta: fields = (‘c_name’, ) model = Child class ParentSerializer(CustomModelSerializer): child = serializers.SerializerMethodField(‘get_child_serializer’) class Meta: model = Parent fields … Read more

NewtonSoft.Json Serialize and Deserialize class with property of type IEnumerable

You don’t need to use JsonConverterAttribute, just keep your model clean and use CustomCreationConverter instead, the code is simpler: public class SampleConverter : CustomCreationConverter<ISample> { public override ISample Create(Type objectType) { return new Sample(); } } Then: var sz = JsonConvert.SerializeObject( sampleGroupInstance ); JsonConvert.DeserializeObject<SampleGroup>( sz, new SampleConverter()); Documentation: Deserialize with CustomCreationConverter

Unserialize in Java a serialized php object

There is serialized-php-parser, which is a Java implementation that can parse php-serialized objects. In general, if you have the choice, I wouldn’t recommend php-serialized as an exchange format, because it isn’t ascii-safe (It contains null-bytes). Go with a format like xml or json instead. If you need a bit of type-information, xmlrpc is a good … Read more
