C # implements JSON serialization and deserialization of instance code

When I do HTTP communication between ASP and unity, when the unity client sends out the form request, I want to return the data he wants to request in JSON format to the client, so that the client can parse it. The server side of this piece involves the serialization and deserialization of JSON.

Both methods have examples, the first is to store objects with a generic collection, then serialize the collection, and the second is a directly serialized object

Using system;using system.collections.generic;using system.web.script.serialization;using System.Configuration; Using system.runtime.serialization.json;using system.runtime.serialization;using system.io;using System.Text; namespace webapplication1{//method One: Introduce a System.Web.Script.Serialization namespace using the JavaScriptSerializer class for simple serialization [        Serializable] public class Person {private int id;             <summary>///ID//</summary> public int ID {get {return id;}        set {id = value;}        } private string name; <summary>//name////</summary> public string name {get {return n Ame        } set {name = value;} }}//Method Two: Introduce the System.Runtime.Serialization.Json namespace using the DataContractJsonSerializer class to implement serialization//You can use Ignoredatamember: Specify the    Member is not part of the data contract and is not serialized, DataMember: Defining a serialization attribute parameter, using the DataMember property tag field must use the DataContract tag class otherwise the DataMember tag does not work.
