c# - 序列化从 DynamicObject 类派生的类的实例

我有一个派生自 DynamicObject 类的类。在调用 JsonConvert.SertializeObject 时,没有任何动态属性被序列化。

类定义为,

        public class Component : DynamicObject
{
// The inner dictionary.
public Dictionary<string, object> dictionary
= new Dictionary<string, object>();

[JsonProperty(PropertyName = "id")]
public string Id { get; set; }

// If you try to get a value of a property
// not defined in the class, this method is called.
public override bool TryGetMember (
GetMemberBinder binder, out object result)
{
// Converting the property name to lowercase
// so that property names become case-insensitive.
string name = binder.Name.ToLower();

// If the property name is found in a dictionary,
// set the result parameter to the property value and return true.
// Otherwise, return false.
return dictionary.TryGetValue(name, out result);
}

// If you try to set a value of a property that is
// not defined in the class, this method is called.
public override bool TrySetMember (
SetMemberBinder binder, object value)
{
// Converting the property name to lowercase
// so that property names become case-insensitive.
dictionary[binder.Name.ToLower()] = value;

// You can always add a value to a dictionary,
// so this method always returns true.
return true;
}
}

然后我这样做,

dynamic component = new Component();
component.test = "123";

JsonConvert.SerializeObject(component);

最佳答案

您需要覆盖 DynamicObject.GetDynamicMemberNames :

public override IEnumerable<string> GetDynamicMemberNames()
{
return dictionary.Keys;
}
