. NET JSON data for serialization and deserialization operations analysis

You can use the DataContractJsonSerializer class to serialize a type instance to a JSON string and deserialize the JSON string into a type instance. DataContractJsonSerializer under the System.Runtime.Serialization.Json namespace

, the. NET Framework 3.5 is included in System.ServiceModel.Web.dll, and you need to add a reference to it;. NET Framework 4 in System.Runtime.Serialization.

Using DataContractJsonSerializer to serialize and deserialize code:

　

　1:using System;　　2:using System.Collections.Generic;　　3:using System.Linq;　　4:using system.web;　　5:using System.Runtime.Serialization.Json;　　6:using System.IO;　　7:using System.Text;     8:9:///<summary>: JSON serialization and deserialization helper classes one by one://</summary> 12:public class Jsonhelper 13: {14: <summary>://JSON Serialization:///</summary> 17:public static string jsonserializer<t&　　gt; (t): {19:datacontractjsonserializer ser = new DataContractJsonSerializer (typeof (T));　　20:memorystream ms = new MemoryStream (); 21:ser.　　WriteObject (MS, T); 22:string jsonstring = Encoding.UTF8.GetString (ms.　　ToArray ()); 23:ms.　　Close ();　　24:return jsonstring; :} 26:27:///<summary>: JSON deserialization:///</summary> 30:public static T J Sondeserialize<t> (String jsonstring): {32:datacontractjsonserializer ser = new DataContractJsonserializer (typeof (T));　　33:memorystream ms = new MemoryStream (Encoding.UTF8.GetBytes (jsonstring)); 34:t obj = (T) ser.　　ReadObject (MS);　　35:return obj; 36:} 37:}

Serialization Demo:

Simple Object Person:

1:public Class 2: {3: Public     string Name {get; set;}　　4: Public     int Age {get; set;} 5:}

Serialized as a JSON string:

　

1:protected void Page_Load (object sender, EventArgs e) 2: {3: Person     p = new person ();　　4:     p.name = "Zhang San";　　5:     p.age = 28;　　6:7:     String jsonstring = Jsonhelper.jsonserializer<person> (p);　　8:     Response.Write (jsonstring); 9:}

Output Result:

{"Age": +, "Name": "Zhang San"}

Deserialization Demo:

1:protected void Page_Load (object sender, EventArgs e) 2: {3:     string jsonstring = "{\" age\ ": 28,\" name\ ": \" Zhang San \ "}";　　4: Person     p = jsonhelper.jsondeserialize<person> (jsonstring); 5:}

ASP. NET JSON serialization and deserialization can also use JavaScriptSerializer, in the System.Web.Script.Serializatioin namespace, reference System.Web.Extensions.dll is required. You can also use the json.net.
