Json.Net-明确包含一个私有财产 [英] Json.Net - Explicitly include a single private property

问题描述

我有一个对象(ViewModel)，其中有一个私有属性，其中包含有关模型的一些元数据.我想在对象的序列化/反序列化中明确包含此私有属性.

I have an object (ViewModel) in which I have a private property that holds some meta-data about the model. I would like to explicitly include this private property in the serializing/deserializing of the object.

是否可以添加到属性中的Json.Net属性?

Is there a Json.Net Attribute I can add to the property?

public class Customer
{

    private string TimeStamp { get; set; }

    public Guid CustomerId { get; set; }

    public string FirstName { get; set; }

    public string LastName { get; set; }

    public string Name
    {
        get
        {
            return FirstName + " " + LastName;
        }
    }
}

"TimeStamp"属性的值在服务返回之前被注入到类中.

The "TimeStamp" property's value is injected into the class before it is returned by a service.

我希望此属性在json.net序列化/反序列化过程中继续存在，以便可以将其返回给服务.

I would like this property to survive the json.net serialize/deserialize process so it can be returned to the service.

推荐答案

如果要序列化/反序列化privete属性，请使用JsonProperty属性对其进行修饰.您的课程应如下所示:

If you want to serialize/deserialize a privete property, decorate it with the JsonProperty attribute. Your class should look like this:

public class Customer
{
    [JsonProperty]
    private string TimeStamp { get; set; }

    public Guid CustomerId { get; set; }

    public string FirstName { get; set; }

    public string LastName { get; set; }

    public string Name
    {
        get
        {
            return FirstName + " " + LastName;
        }
    }

    public Customer()
    {
        TimeStamp = DateTime.Now.Ticks.ToString();
    }
}

这里的假设是您在构造函数中初始化TimeStamp属性，因为它是私有属性.

The assumption here is that you initialize the TimeStamp property in the constructor since it is a private property.

序列化逻辑如下:

var customer = new Customer
    {
        CustomerId = Guid.NewGuid(),
        FirstName = "Jonh",
        LastName = "Doe"
    };

var json = JsonConvert.SerializeObject(customer, Formatting.Indented);
Console.WriteLine(json);

输出应类似于以下内容:

The output should be similar to the following one:

{
    "TimeStamp": "635543531529938160",
    "CustomerId": "08537598-73c0-47d5-a320-5e2288989498",
    "FirstName": "Jonh",
    "LastName": "Doe",
    "Name": "Jonh Doe"
}

除了TimeStamp和CustomerId属性，由于明显的原因，它们的值将不同.

with the exception of TimeStamp and CustomerId properties, that would have different values from obvious reasons.
