反序列化一个List＆LT;抽象类＆GT;与newtonsoft.json [英] Deserialize a List<AbstractClass> with newtonsoft.json

问题描述

我试图序列化和反序列化的摘要类（为MustInherit 为VB）的列表，obviusly内它有派生类的唯一实例。

i'm trying to serialize and deserialize a list of abstract classes (mustinherit for vb), obviusly inside it there are only instances of derived classes.

我饰以列表参数 JsonProperty（ItemTypeNameHandling = TypeNameHandling.Auto）获得看起来像这样的输出：

I've decorated the list parameter with the JsonProperty(ItemTypeNameHandling = TypeNameHandling.Auto) obtaining an output that look like this:

但是，当我反序列化不停地说，他无法反序列化抽象类。

But when i deserialize it keep saying that he cannot deserialize an abstract class.

的http://james.newtonking.com/json/help/index.html?topic=html/SerializeTypeNameHandling.htm

public class ConcreteClass
{
    private ObservableCollection<AbstractClass> _Nodes = new ObservableCollection<AbstractClass>();
    //<Newtonsoft.Json.JsonProperty(itemtypenamehandling:=Newtonsoft.Json.TypeNameHandling.Auto)>
    public ObservableCollection<AbstractClass> Nodes {
        get { return this._Nodes; }
    }
    public string Name { get; set; }
    public int Id { get; set; }
}

public abstract class AbstractClass
{
    private ObservableCollection<AbstractClass> _Nodes = new ObservableCollection<AbstractClass>();
    [Newtonsoft.Json.JsonProperty(itemtypenamehandling = Newtonsoft.Json.TypeNameHandling.Auto)]
    public ObservableCollection<AbstractClass> Nodes {
        get { return this._Nodes; }
    }
}

删除注释行它的作品！

removing the commented line it works!

推荐答案

这是我的错。 我有一个具体的类拿着的名单，但我把这个装饰只在抽象类列表忘记主要原因之一

it was my fault. I had a concrete class holding the List but i put the decorator only in the AbstractClass list forgetting the main one
