C# Serialize JSON object within JSON objects

Question

I have these entities:

public class Product
{
    public string Code {get;set;}
    public string Name {get;set;}

    public ICollection<Pack> Packs {get;set;}
}

public class Pack
{
    public string Colour {get;set;}
    public string Moq {get;set;}
}

my json object:

var products = [{
    code: 1243123,
    name: "Gel",
    packs: [{
        color: "blue",
        moq: 10
    }]
}];

note the naming differences, i.e. case and american spelling of color. Will the JavaScriptConvert.DeserializeObject() deserialise that correctly?

Or will I have to do it another way?

If I can just have an object where I can access those names directly and there values that would be great!

in your json packs is an array but in your Product class it's a single item, I think this will be an issue — Omri Btian

If you use something like JSON.NET, then you can use attributes to control serialization, such as:

public class Pack
{
    [JsonProperty("color")]
    public string Colour {get;set;}
    [JsonProperty("moq")]
    public string Moq {get;set;}
}

Also, given your expected output, your Product class should look like this I think:

public class Product
{
    [JsonProperty("code")]
    public long Code {get;set;}
    [JsonProperty("name")]
    public string Name {get;set;}
    [JsonProperty("packs")]
    public Pack[] Packs {get;set;}
}

Note Code and Packs type.

that seems really good, just means I cant change my model too much ;)

question: what if I literally just want the ids and one other field pulled out of that json object? the json object is used to make a table so I need all that information, however I cant be bother to write a parse to turn that data into a more simplified form, should I be bothered, will that make it easier, or can you just get the serialiser just to look at certain things?

No worries, I have implement a javascript function pulling out only the information i need, then I created c# objects that match identically, then got Newton JsonConvert.DeserialiseObject<>() to convert it, works a treat :)

If you use DataContractJsonSerializer instead, you can put attributes to your properties, giving them different names in generated/parsed JSON:

[DataContract]
public class Pack
{
    [DataMember(Name = "color")]
    public string Colour {get;set;}

    [DataMember(Name = "moq")]
    public string Moq {get;set;}
}
