The following is a detailed analysis of JSON serialization and deserialization. If you need it, refer to Method 1: Introduce System. web. script. the Serialization namespace uses the JavaScriptSerializer class to implement a simple Serialization
General use of an entity to parse a JSON collusion often exists in the following situations:1. The entity attribute serialized into JSON is more than the Entity attribute parsing the JSON string.2. Parsing the JSON string has more entity properties
