调用无参构造函数，new出一个实例，然后使用Json字符串中包含的字段or属性为成员赋值，Json字符串未提供的字段or属性的值是无参构造函数初始化的值或是0，false，null；private的字段or属性会用默认值或无参构造函数去初始化。若类未提供无参构造函数，则调用有参构造函数，但是要保证类仅有一个有参构造函数，多个有参构造函数时，若不指定哪个构造函数来反序列化，编译器会报错。所以，尽可能的为会进行序列化和反序列化的类提供无参构造函数。
class Person
{
private string name;
public string Name { get => name; set => name = value; }
//年龄
private int age;
public int Age { get => age; set => age = value; }
//城市
public string City { get; set; }
//技能
public List<string> languages;
public Person()
{
Name = "Andrew Magic";
Age = 20;
City = "Zhuhai";
languages = new List<string>();
}
}
Person p1 = new Person(); string p1JsonStr = JsonConvert.SerializeObject(p1);
string p2JsonStr = "{\"Name\":\"Jack\" }";
Person p2 = JsonConvert.DeserializeObject<Person>(p2JsonStr);
Person p3 = new Person();
p3.Name = "LiMing";
p3.Age = 22;
p3.City = "Shanghai";
p3.languages.AddRange(new string[] { "C", "Java", "PHP" });
Person p4 = new Person();
p4.Name = "ZhangSan";
p4.Age = 20;
p4.City = "Beijing";
p4.languages.AddRange(new string[] { "C#", "Python", "Go" });
List<Person> list = new List<Person> { p3, p4 };
string objectsJsonStr = JsonConvert.SerializeObject(list);
List<Person> list = JsonConvert.DeserializeObject<List<Person>>(objectsJsonStr);
foreach (Person item in list)
{
Console.WriteLine(item.Name);
}
