Simple analysis of JSON serialization and anti-serialization _ practical skills

method One: Introduce System.Web.Script.Serialization namespaces to implement simple serialization using JavaScriptSerializer class Serialization class: Personnel

Copy Code code as follows:

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

To perform serialization deserialization:

Copy Code code as follows:

protected void Page_Load (object sender, EventArgs e)
{
Personnel personnel = new personnel ();
Personnel. Id = 1;
Personnel. Name = "small white";

JavaScriptSerializer Jsonserializer = new JavaScriptSerializer ();
Perform serialization
string R1 = Jsonserializer.serialize (Personnel);

Perform deserialization
Personnel _personnel = jsonserializer.deserialize<personnel> (r1);
}

R1 output: {"Id": 1, "Name": "Small White"}
You can use the Scriptignore property tag to not serialize public properties or public fields.

Copy Code code as follows:

public class personnel
{
[Scriptignore]
public int Id {get; set;}
public string Name {get; set;}
}

R1 Output Result: {"Name": "Small White"}

method Two: Introducing System.Runtime.Serialization.Json namespaces to implement serialization using the DataContractJsonSerializer class

Serialization class: People

Copy Code code as follows:

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

perform serialization deserialization

Copy Code code as follows:

protected void Page_Load (object sender, EventArgs e)
{
People people = new people ();
People. Id = 1;
People. Name = "small white";

DataContractJsonSerializer json = new DataContractJsonSerializer (people. GetType ());
String Szjson = "";
Serialization of
using (MemoryStream stream = new MemoryStream ())
{
Json. WriteObject (stream, people);
Szjson = Encoding.UTF8.GetString (stream. ToArray ());
}
Deserialization
using (MemoryStream ms = new MemoryStream (Encoding.UTF8.GetBytes (Szjson))
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer (typeof (People));
People _people = (people) serializer. ReadObject (MS);
}
}

Szjson output: {"Id": 1, "Name": "Small White"}

You can use Ignoredatamember: Specify that the member is not part of a data contract and is not serialized, DataMember: Define serialization Property arguments, use the DataMember property tag field to use the DataContract tag class Otherwise, the DataMember tag does not work.

Copy Code code as follows:

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

Output result: {"id": 1}
