Analysis on JSON serialization and deserialization

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 class: Personnel

    public class Personnel        {            public int Id { get; set; }            public string Name { get; set; }        }

Execute serialization deserialization:

Protected void Page_Load (object sender, EventArgs e) {Personnel personnel = new Personnel (); personnel. id = 1; personnel. name = ""; JavaScriptSerializer jsonSerializer = new JavaScriptSerializer (); // execute serialized string r1 = jsonSerializer. serialize (personnel); // execute deserialization of Personnel _ Personnel = jsonSerializer. deserialize
 
  
(R1 );}
 

R1 output result: {"Id": 1, "Name": ""}
You can use the ScriptIgnore attribute to mark public or public fields that are not serialized.

        public class Personnel        {            [ScriptIgnore]            public int Id { get; set; }            public string Name { get; set; }        }

R1 output result: {"Name": ""}

Method 2: introduce the System. Runtime. Serialization. Json namespace and use the DataContractJsonSerializer class for Serialization.

Serialization class: People

        public class People        {            public int Id { get; set; }            public string Name { get; set; }        }

Execute serialization deserialization

Protected void Page_Load (object sender, EventArgs e) {People people = new People (); people. id = 1; people. name = ""; DataContractJsonSerializer json = new DataContractJsonSerializer (people. getType (); string szJson = ""; // serialize using (MemoryStream stream = new MemoryStream () {json. writeObject (stream, people); szJson = Encoding. UTF8.GetString (stream. toArray ();} // deserialization of using (MemoryStream MS = new MemoryStream (Encoding. UTF8.GetBytes (szJson) {DataContractJsonSerializer serializer = new DataContractJsonSerializer (typeof (People); People _ people = (People) serializer. readObject (MS );}}

SzJson output result: {"Id": 1, "Name": ""}

You can use IgnoreDataMember to specify that the member is not part of the Data Protocol and is not serialized. DataMember: defines the serialization attribute parameters. Fields marked with the DataMember attribute must use the DataContract tag class. Otherwise, the DataMember tag does not work.

[DataContract]        public class People        {            [DataMember(Name = "id")]            public int Id { get; set; }            [IgnoreDataMember]            public string Name { get; set; }        }

Output result: {"id": 1}
