反序列化$ ref和$ id [英] Deserializing $ref and $id

问题描述

因此，我试图反序列化具有以下属性的对象:$ ref和$ id.我尝试在Dictionary和通过JsonPropertyAttribute指定namingconventions的对象之间进行切换. 序列化有效，但是反序列化无效.我不断收到的错误是:

So I'm trying to deserialize an object that has properties: $ref and $id. I have tried going between Dictionary as well as an object where I have specified namingconventions via JsonPropertyAttribute. Serialization works, but deserialization doesn't. The error I keep getting is:

在JSON字符串中找到其他文本 完成反序列化对象后.

Additional text found in JSON string after finishing deserializing object.

所有三个样本均失败的样本代码.

Sample code where all three samples, fail.

[Serializable]
public class Ref
{
    [JsonProperty(PropertyName = "$ref")]
    public virtual string RefName { get; set; }
    [JsonProperty(PropertyName = "$id")]
    public virtual int Id { get; set; }
}

[Serializable]
public class Child
{
    public virtual string Name { get; set; }
    [JsonProperty(IsReference = true)]
    public virtual Ref Father { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        //Additional text found in JSON string after finishing deserializing object.
        //Test 1
        var reference = new Dictionary<string, object>();
        reference.Add("$ref", "Persons");
        reference.Add("$id", 1);

        var child = new Dictionary<string, object>();
        child.Add("_id", 2);
        child.Add("Name", "Isabell");
        child.Add("Father", reference);

        var json = JsonConvert.SerializeObject(child);
        var obj = JsonConvert.DeserializeObject<Dictionary<string, object>>(json); //Exception

        //Test 2
        var refOrg = new Ref {RefName = "Parents", Id = 1};
        var refSer = JsonConvert.SerializeObject(refOrg);
        var refDeser = JsonConvert.DeserializeObject<Ref>(refSer); //Exception

        //Test 3
        var childOrg = new Child {Father = refOrg, Name = "Isabell"};
        var childSer = JsonConvert.SerializeObject(childOrg);
        var childDeser = JsonConvert.DeserializeObject<Child>(refSer); //Exception
    }
}

推荐答案

在尝试反序列化swagger/json模式文档时，我遇到了相同的问题.解决方案是:

I have the same issue when trying to deserialize a swagger/json schema document. The solution is:

JsonSerializerSettings settings = new JsonSerializerSettings();
settings.MetadataPropertyHandling = MetadataPropertyHandling.Ignore;
