Recently, JSON. Net has updated the new version and made significant improvements in serialization and deserialization. It is declared that its performance is faster than any other JSON serialization mechanism, such as javascriptserializer and WCF datacontractjsonserializer.
From the data results, the speed of JSON. NET is indeed much faster than that of Microso

there are extra fields in the JSON, it will be discarded directly, if the JSON is missing a field, then directly ignore the variable assignment in the struct, without error.
