Cannot deserialize the current JSON object api REST To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object.

Serialization and Deserialization You can then use the interface to customize the serialization and deserialization process. For more information, see Data Contract Surrogates. Serialization. The following information applies to any class that inherits from the XmlObjectSerializer, including the DataContractSerializer and NetDataContractSerializer classes. Simple Serialization

- Here's the way you could implement serializable so that *ALL* descendant serialize themselves without the need of re-writing for all descendant the functions serialize() and unserialize(). Note : this will only serialize visible properties, this it won't serialize private descendant properties.

- Working with JSON Data. HTTP-based Web services frequently use JavaScript Object Notation (JSON) messages to return data back to the client. JSON objects can easily be instantiated in JavaScript, without parsing logic, which makes it a convenient format for messages in Web applications.

JavaScriptSerializer â Dictionary to JSON Serialization and Deserialization To use the first Serialize method that returns string or to use the second Serialize method that accepts two parameters where the second parameter is the StringBuilder where the JSON output string will be assigned. I will show both ways at once.

JSON JSON Schema is based on the concepts from XML Schema (XSD), but is JSON-based. The JSON data schema can be used to validate JSON data. As in XSD, the same serialization/deserialization tools can be used both for the schema and data. The schema is self-describing.

- The basic mechanism of Java serialization is simple to use, but there are some more things to know. As mentioned before, only objects marked Serializable can be persisted. The java.lang.Object class does not implement that interface. Therefore, not all the objects in Java can be persisted automatically.

Finding Non-disposed Contexts in Entity Framework 6.x Applications Introduction. Object context acts as a unit of work in entity framework based applications and should have a short life time. It's easy to forget not disposing object contexts, which leads to memory leaks and also leaves too many related connection objects not disposed as well.Here, we have 2 simple methods.t the end, to find out which contexts are not disposed, we can query connections list and filter connections with Status != ConnectionStatus.Disposed. Also it's important to check the internal properties of ConditionalWeakTable object.
