[英]Serialize object when the object inherits from list
[DataContract]
public class A : List<B>
{
[DataMember]
public double TestA { get; set; }
}
[DataContract]
public class B
{
[DataMember]
public double TestB { get; set; }
}
With the model above I try to serialize the following object: 使用上面的模型,我尝试序列化以下对象:
List<A> list = new List<A>()
{
new A() { TestA = 1 },
new A() { TestA = 3 }
};
json = JsonConvert.SerializeObject(list);
//json: [[],[]]
Where are my two values from TestA
? TestA
中我的两个值在TestA
? It's possible duplicate from this thread (XML), but I want to know if there is no option to include those values by setting some JSON serialize option? 这可能是从这个线程 (XML)重复,但我想知道是否没有选项通过设置一些JSON序列化选项来包含这些值?
Note: Creating a property List<B>
in class A
instead of inheritance is no option for me. 注意:在A
类中创建属性List<B>
而不是继承对我来说是没有选择的。
According to the comments above (thanks!) there are two ways to get a correct result: 根据上面的评论(谢谢!)有两种方法可以获得正确的结果:
JsonConverter
( see here ) 实现自定义JsonConverter
( 参见此处 ) Anyway, inherit from List<T>
is rare to be a good solution ( see here ) 无论如何,从List<T>
继承很少是一个很好的解决方案( 见这里 )
I've tried it with the workarround: 我已经尝试过workarround:
[JsonObject(MemberSerialization = MemberSerialization.OptIn)]
public class A : List<B>
{
[JsonProperty]
public double TestA { get; set; }
[JsonProperty]
public B[] Items
{
get
{
return this.ToArray();
}
set
{
if (value != null)
this.AddRange(value);
}
}
}
public class B
{
public double TestB { get; set; }
}
This works for serialization and deserialization. 这适用于序列化和反序列化。 Important: Items
must be an Array
of B
and no List<B>
. 要点: Items
必须是B
的Array
且没有List<B>
。 Otherwise deserialization doesn't work for Items
. 否则反序列化不适用于Items
。
