C#如何在从DynamicObject继承的类上序列化(JSON，XML)常规属性 [英] C# How to serialize (JSON, XML) normal properties on a class that inherits from DynamicObject

问题描述

我正在尝试序列化从DynamicObject继承的类的实例.我毫不费力地将动态属性进行序列化(为简洁起见，此处未进行演示)，但是普通"属性似乎并不麻烦.无论序列化类如何，我都会遇到相同的问题:JavaScriptSerializer，JsonConvert和XmlSerializer都是相同的.

I am trying to serialize an instance of a class that inherits from DynamicObject. I've had no trouble getting the dynamic properties to serialize (not demonstrated here for brevity), but "normal" properties don't seem to make the trip. I experience the same problem regardless of serialization class: it's the same for JavaScriptSerializer, JsonConvert, and XmlSerializer.

public class MyDynamicClass : DynamicObject
{
    public string MyNormalProperty { get; set; }
}

...

MyDynamicClass instance = new MyDynamicClass()
{
    MyNormalProperty = "Hello, world!"
};

string json = JsonConvert.SerializeObject(instance);
// the resulting string is "{}", but I expected to see MyNormalProperty in there

序列化字符串中不会显示MyNormalProperty吗?有技巧吗，还是我误解了从DynamicObject继承的一些基本知识?

Shouldn't MyNormalProperty show up in the serialized string? Is there a trick, or have I misunderstood something fundamental about inheriting from DynamicObject?

推荐答案

您可以使用System.Runtime.Serialization

    [DataContract]
    public class MyDynamicClass : DynamicObject
    {
        [DataMember]
        public string MyNormalProperty { get; set; }
    }

这样，无论您使用哪种序列化程序，序列化都能正常工作...

This way the serialisation will work no matter what serialiser you use...
