C#json字符串序列化和反序列化

以下是C#中进行Json字符串序列化和反序列化的示例代码：

1. 序列化实体类对象为Json字符串

using Newtonsoft.Json;

// 定义实体类
public class Student
{
    public int studentID { get; set; }
    public string studentName { get; set; }
    public int studentAge { get; set; }
    public string studentSex { get; set; }
}

// 创建实体类对象
Student studentOne = new Student();
studentOne.studentID = 1;
studentOne.studentName = "张三";
studentOne.studentAge = 18;
studentOne.studentSex = "男";

// 序列化为Json字符串
string json = JsonConvert.SerializeObject(studentOne);
Console.WriteLine(json); // 输出：{"studentID":1,"studentName":"张三","studentAge":18,"studentSex":"男"}

2. 反序列化Json字符串为实体类对象

using Newtonsoft.Json;

// 定义实体类
public class Student
{
    public int studentID { get; set; }
    public string studentName { get; set; }
    public int studentAge { get; set; }
    public string studentSex { get; set; }
}

// 反序列化为Student实体类对象
string json = "{\"studentID\":1,\"studentName\":\"张三\",\"studentAge\":18,\"studentSex\":\"男\"}";
Student studentTwo = JsonConvert.DeserializeObject<Student>(json);
Console.WriteLine(studentTwo.studentName); // 输出：张三
