c# - 反序列化 JSON 时遇到 Null

Question

我有json消息

{"code":200,
"description":{
 "15":{"id":"15","name":"US"},
 "25":{"id":"25","name":"Canada"},
 "msg":"Ok"}}

我正在尝试用这样的类反序列化它

public class NewCountry
{
    public string id { get; set; }
    public string name { get; set; }
}

public class NewCountryDescription
{
    public List<NewCountry> Countries{ get; set; }
    public string msg { get; set; }
}

public class RootObject
{
    public int code { get; set; }
    public NewCountryDescription description { get; set; }
}

var ListOfCountries = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(res);

但是我在 NewCountry 总是得到 null 我做错了什么？

Answer 1

如果您从 json 中删除 msg 或将其移动到其他地方(不在描述中)，它将起作用:

    {"code":200,
"description":{
 "15":{"id":"15","name":"US"},
 "25":{"id":"25","name":"Canada"}
 }}


    public class RootObject
    {
        public int code { get; set; }
        public Dictionary<string, NewCountry> description { get; set; }
    }

    public class NewCountry
    {
        public string id { get; set; }
        public string name { get; set; }
    }
