[英]Can I make a strict deserialization with Newtonsoft.Json?
I am using Newtonsoft.Json to serialize/deserialize objects. 我正在使用Newtonsoft.Json来序列化/反序列化对象。
As far as I know a deserialization can not be successful if the class does not have parameterless constructor. 据我所知,如果类没有无参数构造函数,则反序列化无法成功。 Example, 例,
public class Dog
{
public string Name;
public Dog(string n)
{
Name = n;
}
}
For this class below code generates the object correctly. 对于下面这个类,代码正确生成对象。
Dog dog1 = Newtonsoft.Json.JsonConvert.DeserializeObject<Dog>("{\"Name\":\"Dog1\"}");
For me, surprisingly it generates the object correctly with below codes also. 对我来说,令人惊讶的是,它也可以使用以下代码正确生成对象。
Dog dog2 = Newtonsoft.Json.JsonConvert.DeserializeObject<Dog>("{\"name\":\"Dog2\"}");
Dog dog3 = Newtonsoft.Json.JsonConvert.DeserializeObject<Dog>("{\"n\":\"Dog3\"}");
Dog dog4 = Newtonsoft.Json.JsonConvert.DeserializeObject<Dog>("{\"N\":\"Dog4\"}");
Now all I can think is 现在我能想到的就是
Here comes my question: 这是我的问题:
If my class is something like this, 如果我的班级是这样的,
public class Dog
{
public string Name;
public Dog(string name)
{
Name = name + "aaa";
}
}
and generating object with 和生成对象
Dog dog1 = Newtonsoft.Json.JsonConvert.DeserializeObject<Dog>("{\"Name\":\"Dog1\"}");
then created object gives me dog1.Name = "Dog1aaa"
instead of dog1.Name = "Dog1"
. 然后创建对象给我dog1.Name = "Dog1aaa"
而不是dog1.Name = "Dog1"
。 How can I deserialize the object correctly(maybe overriding Name
after creating the object)? 如何正确反序列化对象(可能在创建对象后覆盖Name
)? Is there a way for strict deserialization? 有没有办法严格反序列化?
Thanks in advance 提前致谢

You can declare another constructor and force Json.Net to use it 您可以声明另一个构造函数并强制Json.Net使用它
public class Dog
{
public string Name;
[JsonConstructor]
public Dog()
{
}
public Dog(string name)
{
Name = name + "aaa";
}
}
有这样的事情
JsonConvert.DeserializeObject("json string", typeof(some object));
