C# 用数组反序列化 json

Question

I want to deserialize a json that contains an array into a class and i dont know how it works. I am using C# WPF. What i got to work so far:

Class:

class Truppe
{
    public int id { get; set; }
    public int nr { get; set; }
    public int tribe { get; set; }
}

Json Deserialize:

Troop = "{\"id\":1,\"nr\":1,\"tribe\":1}";
Truppe JSONObj = JsonConvert.DeserializeObject<Truppe>(Troop);

so far it works totally fine. But now i want an array in the class containing the costs as an array. So it shall look something like that (not working)

Class:

class Truppe
{
    public int id { get; set; }
    public int nr { get; set; }
    public int tribe { get; set; }
    public int[,] costs { get; set; }
}

Json Deserialize:

Troop = "{\"id\":1,\"nr\":1,\"tribe\":1,\"costs\":{\"1\":75,\"2\":50,\"3\":100,\"4\":0}}";
Truppe JSONObj = JsonConvert.DeserializeObject<Truppe>(Troop);

can someone help me get the correct form?

Answer 1

Ok, i found out how it works with that Syntax of Json. Instead of

public int[,] costs { get; set; }

i had to use

public Dictionary<string, int> costs { get; set; }
