Json.使用对象列表进行反序列化

Question

我正在处理来自Windows Phone 7客户端服务的JSON响应(如下所示)。我使用Json。NET将它们反序列化为一个对象，该对象包含产品列表。

但是在我反序列化之后，当我查看我的servicerresponse对象时，我可以看到一个包含2个产品的列表。但是当我展开产品对象时，product (Name, ExpiryDate…)下的字段等)都为空

我想我的问题是我定义servicerresponse类的方式。谁能帮我解决这个问题，得到正确的输出?

反序列化代码:

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

我的Json响应字符串:

{ "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;
}

Answer 1

从json中删除"product"对象名称，因为这只是一个没有命名项的数组。

{ "serviceresponse" : 
{ "company" : "ford", "success" : "Yes", "products" : [
  {
    "Name": "Product 1",
    "ExpiryDate": "/Date(978048000000)/",
    "Price": "99.95",
    "Sizes": "1"
  },      
  {
    "Name": "Product 2",
    "ExpiryDate": "/Date(1248998400000)/",
    "Price": "12.50",
    "Sizes": "1"
  }
], "callbackformore" : "No", "message" : "1" 
} 
}

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Json字符串生成c#类。然后我打开生成的类，发现类是如何布局的。并相应地修改了我的Datacontract。

在我的例子中，我必须围绕对象列表创建另一个数据契约。所以应该是这样的

[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;
}
