如何将JSON反序列化为对象属性（使用DataContractJsonSerializer） [英] How to deserialize JSON to object property (using DataContractJsonSerializer)

问题描述

我确实有这些JSON文本反序列化（它们是更大结构的一部分，只是为了保持简单）：

I do have these JSON text to deserialize (they are part of bigger structure, just to keep it simple):

{"name":"whatever","value":0}
{"name":"objectProperty","value":{"A":1,"B":2,"C":3,"D":4}}

当我想要反序列化为C＃对象时：

when I do want to deserialize into the C# object:

public class Rootobject
{
    public string name { get; set; }
    public int value { get; set; }
}

我将获得第一种情况：

I will get in 1st case:

whatever : 0

我得到的第二种情况是
：

in the second case I get:

objectProperty : {object}

问题是我无法从

the problem is that I'm not able to get any value from the

{object}

获得任何价值。



当我使用这个C＃类进行反序列化时：

.

when I do use this C# class to deserialize:

public class Rootobject
{
    public string name { get; set; }
    public Value value { get; set; }
}

public class Value
{
    public int A { get; set; }
    public int B { get; set; }
    public int C { get; set; }
    public int D { get; set; }
}

我会收到错误：

I will get an error:

Expecting state 'Element'.. Encountered 'Text'  with name '', namespace ''.

有没有办法怎么样告诉反序列化器它应该反序列化哪个类？或者任何想法如何解决这个问题？



thx，

R.

Is there a way how to tell deserializer to which class it should deserialize? Or any idea how to solve this problem?

thx,
R.

推荐答案

将

[DataContract]

注释添加到您的班级，并将

annotation to your class and

[DataMember]

注释添加到您的班级properties

annotation to you class properties

[DataContract]
    internal class Person
    {
        [DataMember]
        internal string name;

        [DataMember]
        internal int age;
    }

我的解决方案是使用 http：/ /www.newtonsoft.com/json [ ^ ]而不是标准系统运行时序列化。



这个库将复杂内容放在字符串表示中，这对我来说已经足够了。

Solution for me is to use http://www.newtonsoft.com/json[^] instead of standard system runtime serialization.

this library puts "complex content" in string representation which is enough for me for now.
