First of all, you need to understand what JSON is, you can click https://www.ibm.com/developerworks/cn/web/wa-lo-json/ to learn more about JSON, I will briefly introduce JSON here:
JSON stands for Javascrip{filter}t Object Natation, which is a lightweight data exchange format that is ideal for server interaction with Javascrip{filter}t. Like XML, JSON is a plain text-based data format. Since JSON is inherently prepared for Javascrip{filtering}t, the data format of JSON is very simple, you can transfer a simple String, Number, Boolean, an array, or a complex Object object in JSON.
In the .NET environment, we use Json.net to serialize and deserialize JSON data.
Start by clicking Connect http://json.codeplex.com/ to download the JSON. .NET plugins and code.
Then make a reference Newtonsoft.Json.dll in your project
Add namespace: using Newtonsoft.Json;
The following are some important methods and examples of JSON serialization and deserialization:
JsonConvert.SerializeObject(object value), which has an overload method JsonConvert.SerializeObject(object value, params JsonConverter[] converters).
JsonConvert.DeserializeObject(string value, Type type), deserialized, it has an overload method JsonConvert.DeserializeObject(string value, Type type, params JsonConverter[] converters)
These two methods can achieve basic serialization and deserialization requirements, see the following examples:
First, let's build a Person class code as follows:
public class Person
{
private string name;
public string Name
{
get { return name; }
set { name = value; }
}
private int age;
public int Age
{
get { return age; }
set { age = value; }
}
}
1) Serialization
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Newtonsoft.Json;
namespace JSONnet
{
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Person person = new Person();
person. Name = "GoldenEasy";
person. Age = 25;
string strSerializeJSON = JsonConvert.SerializeObject(person);
Response.Write(strSerializeJSON);
}
}
}
Output:
{"Name":"GoldenEasy","Age":25}
2) deserialization
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Newtonsoft.Json;
namespace JSONnet
{
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Person person = new Person();
person. Name = "GoldenEasy";
person. Age = 25;
string strSerializeJSON = JsonConvert.SerializeObject(person);
Person user = (Person)JsonConvert.DeserializeObject(strSerializeJSON, typeof(Person));
Response.Write(user. Name);
}
}
}
The output result is: GoldenEasy |
