c# - 将键值对反序列化为列表

Question

谁能告诉我如何将键值对反序列化为列表？即从 JSON 响应中，我想从下面的响应中获取国家和代码列表。我正在使用 Newtonsoft.Json:

{
    "status": "SUCCESS",
    "message": "something",
    "data": {
        "trade_origin_iso3country": "GBR",
        "countries": {
            "ARM ": "Armenia",
            "BLR": "Belarus ",
            "DNK": "Denmark",
            "GBR": "United Kingdom",
            "MCO": "Monaco"
        }
    }
}

如果您创建一个具有以下定义的类:

public class MyObject 
{
     public string status { get; set; }
     public string message { get; set; }
     public MySubObject data { get; set; }
}

public class MySubObject 
{
    public string trade_origin_iso3country { get; set;}
    public Dictionary<string,string> countries { get;set;}
}

您可以只使用最方便的(至少是 IMO)语法来获取具有已填充字典的对象。

var myResult = JsonConvert.Deserialize<MyObject>(json);

获取列表:

var result = (
     from kvp in myResult.data.countries
     select $"{kvp.Key}: {kvp.Value}").ToList()
