Json.NET:使用对象列表进行反序列化 [英] Json.NET: Deserialization with list of objects

问题描述

我正在从Windows Phone 7客户端上的服务处理JSON响应(如下所示).我正在使用Json.NET将它们反序列化为一个对象，该对象包含产品列表.

I am processing JSON responses (displayed below) from a service on my Windows Phone 7 client. I am using Json.NET to deserialize them into an object, which contains List of products.

但是在反序列化之后，当我查看服务响应对象时，可以看到2种产品的列表.但是当我扩展产品对象时，产品下的字段(名称，ExpiryDate ...等)都为空.

But after I deserialize, when I looked into my serviceresponse object, I can see a list of 2 products. But when I expand the product object, the fields under product (Name, ExpiryDate... etc ) are all null.

我想我的问题在于定义服务响应类的方式.有人可以帮助我解决问题并获得正确的输出.

I guess my problem is with the way I have defined my serviceresponse class. Can someone help me to resolve the issue and get the correct output.

我的反序列化代码:

serviceresponse deserializedProduct = JsonConvert.DeserializeObject<serviceresponse>(json);

我的Json响应字符串:

My Json response String:

{ "serviceresponse" : 

{ "company" : "ford", "success" : "Yes", "products" : [
  {"product" : 

      {
        "Name": "Product 1",
        "ExpiryDate": "\/Date(978048000000)\/",
        "Price": "99.95",
        "Sizes": "1"
      }
  },
  {"product" : 
      {
        "Name": "Product 2",
        "ExpiryDate": "\/Date(1248998400000)\/",
        "Price": "12.50",
        "Sizes": "1"
      }
  }
], "callbackformore" : "No", "message" : "1" 

    } 
}

我的服务响应类:

[DataContract]
public class serviceresponse
{
    [DataMember]
    public String company;
    [DataMember]
    public String success;
    [DataMember]
    public List<product> products;
    [DataMember]
    public String callbackformore;
    [DataMember]
    public String message;
}

[DataContract]
public class product
{
    [DataMember]
    public String Name;
    [DataMember]
    public String ExpiryDate;
    [DataMember]
    public String Price;
    [DataMember]
    public String Sizes;
}

推荐答案

我最终这样做了.我发现了这个很棒的工具 Jsonclassgenerator .它可以为输入的Json字符串生成C#类.然后，我打开生成的类，并发现如何布置这些类.并相应地修改了我的Datacontract.

I ended up doing this. I found this awesome tool Jsonclassgenerator. It could generate C# classes for the input Json string. Then I opened the generated class and found how the classes are laid out. And modified my Datacontract accordingly.

就我而言，我必须围绕对象列表创建另一个数据协定.所以应该是这样.

In my case, I have to create another data contract surrounding the list of objects. So it should be like this.

[DataContract]
public class serviceresponse
{
    [DataMember]
    public String company;
    [DataMember]
    public String success;
    [DataMember]
    public List<product> products;
    [DataMember]
    public String callbackformore;
    [DataMember]
    public String message;
}
[DataContract]
public class product
{
    [DataMember(Name = "product")]
    public product2 _product;
}
[DataContract(Name = "product")]
public class product2
{
    [DataMember]
    public String Name;
    [DataMember]
    public String ExpiryDate;
    [DataMember]
    public String Price;
    [DataMember]
    public String Sizes;
}
