Deserializing partial json content with RestSharp-CodePudding

I'm using RestSharp for making requests and deserializing responses into C# models with NewtonsoftJsonSerializer. And I ran into the situation where I am getting 2 similar json strings.

First:

{  
   "updated": "",
   "data":{
       "categories":[...],
       "products": [...]
   }
}

Second:

{  
   "updated": "",
   "categories":[...],
   "products": [...]
}

For deserializing the first one I'm using the following C# model:

public class Root
{
    [JsonProperty("updated")] public string Updated{ get; set; }
    [JsonProperty("data")] public Data Items{ get; set; }
}

public class Data
{
    [JsonProperty("categories")] public List<Category> Categories { get; set; }
    [JsonProperty("products")] public List<Dish> Products { get; set; }
}

public class Category{...} 

public class Dish{...}

I now I can use Data class for deserializing the second json string. But I want to use one model for deserialising both of them. And deserializing first json into Data class obviously returns null. Basically I need only categories and products lists.

What should I change in my model to make it happen? Is there any attribute that can help?

CodePudding user response：

If you define class like this and deserialize json responses into this class, you can have a single class but some fields will be null for each different response.

public class Data
{
    [JsonProperty("updated")] public string Updated{ get; set; }
    [JsonProperty("categories")] public List<Category> Categories { get; set; }
    [JsonProperty("products")] public List<Dish> Products { get; set; }
    [JsonProperty("data")] public Data Items{ get; set; }
}

If you don't want to do it as above, I think you should create a custom deserializer as it is described here: How to implement custom JsonConverter in JSON.NET?

try this

   var jsonParsed = JObject.Parse(json);

    Root data;

    if (jsonParsed["data"] != null)
        data = jsonParsed.ToObject<Root>();
    else
    {
        data = new Root
        {
            Updated = (string)jsonParsed["updated"],
            Items = new Data
            {
                Categories = jsonParsed["categories"].ToObject<List<Category>>(),
                Products = jsonParsed["products"].ToObject<List<Dish>>()
            }
        };
    }
