Newtonsoft JSON反序列化接口

Question

I have a problem with deserializing the following sample JSON snippet:

{
   "list":{
       "A":{"ClassA":{"PropertyA":"test"}},
       "B":{"ClassB":{"PropertyB":"test"}}
    }
}

With my ClassA:

public class ClassA:IInterface{
   public String PropertyA{get; set;}
}
public class ClassB:IInterface{
   public String PropertyB{get; set;}
}

I want the JsonConverter to create a ClassA or ClassB with the PropertyA or PropertyB from the JSON. The ClassA or ClassB is embedded in a Dictionary.

I can also put the full class name with namespace there but I wasn't really able to make it work.

Thanks in advance for any help

Answer 1

You need a wrapper class:

public class ListClass
{
    public WrapperList List { get; set; }
}

public class WrapperList
{
    public WrapperA A { get; set; }
    public WrapperB B { get; set; }
}

public class WrapperA
{
    public ClassA ClassA { get; set; }
}

public class WrapperB
{
    public ClassB ClassB { get; set; }
}

public class ClassA : IInterface
{
    public String PropertyA { get; set; }
}

public class ClassB : IInterface
{
    public String PropertyB { get; set; }
}

Then:

var list = JsonConvert.DeserializeObject<ListClass>(json);
