.net 实体类与json相互转换

.net 实体类与json相互转换

1.使用Newtonsoft.Json库进行转换：

1.1 将实体类转换为json字符串：

public class Person
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
}

var person = new Person
{
    Id = 1,
    Name = "张三",
    Age = 18
};

var jsonStr = JsonConvert.SerializeObject(person);

1.2 将json字符串转换为实体类：

var jsonStr = "{\"Id\":1,\"Name\":\"张三\",\"Age\":18}";

var person = JsonConvert.DeserializeObject<Person>(jsonStr);

2.使用System.Text.Json库进行转换

2.1 将实体类转换为json字符串

var person = new Person
{
    Id = 1,
    Name = "张三",
    Age = 18
};

var jsonStr = JsonSerializer.Serialize(person);

2.2 将json字符串转换为实体类

var jsonStr = "{\"Id\":1,\"Name\":\"张三\",\"Age\":18}";

var person = JsonSerializer.Deserialize<Person>(jsonStr);
