将 JSON C# 类调用到方法中

Question

我有一个这样的 JSON API，

{
 "pokemon": {
 "currentPokemon": 1,
 "total": 1,
 "totalCount": 1,
 },
"collections": [
{
  "pokemonId": 2310,
  "pokemonName": "Pikachu",
  "pokemonType": "Land",
  "status": {
    "Active": "YES",
    "Holder": "ASH"
  },
  "power": {
    "Type": 10,
    "name": "Thunder"
  },

}
]
}

我有这些 API 的 C# 类

Public ClassPokemonster 
{

public class RootObject
{
 [JsonProperty("pokemon")]
 public Pokemon Pokemon { get; set; }
 [JsonProperty("collections")]
 public List<Collection> Collections { get; set; }
}
public class Pokemon
{
 [JsonProperty("currentPokemon")]
 public int CurrentPokemon { get; set; }
 [JsonProperty("total")]
 public int Total { get; set; }
 [JsonProperty("totalCount")]
 public int TotalCount { get; set; }
}
public class Collection
{
 [JsonProperty("pokemonId")]
 public int PokemonId { get; set; }
 [JsonProperty("pokemonName")]
 public string PokemonName { get; set; }
 [JsonProperty("pokemonType")]
 public string PokemonType { get; set; }
 [JsonProperty("status")]
 public Status Status { get; set; }
 [JsonProperty("power")]
public Power Power { get; set; }
}
public class Status
{
 [JsonProperty("Active")]
 public string Active { get; set; }
 [JsonProperty("Holder")]
 public string Holder { get; set; }
}
public class Power 
{
 [JsonProperty("Type")]
 public int Type { get; set; }
 [JsonProperty("name")]
 public string Name { get; set; }
}
}

我正在尝试使用此方法断言与 API 值匹配的值

         Driver.Instance.Navigate().GoToUrl(url);
        //WebRequest
        HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(url);
        getRequest.Method = "GET";

        var getResponse = (HttpWebResponse)getRequest.GetResponse();
        Stream newStream = getResponse.GetResponseStream();
        StreamReader sr = new StreamReader(newStream);

        //Deserialize JSON results
        var result = sr.ReadToEnd();
        Pokemonster deserializedObjects = JsonConvert.DeserializeObject<Pokemonster>(result);

我正在尝试以这种方式断言，

  Assert.Equal("2310", deserializedObject.Collections.PokemonId.ToString());

我的断言没有获取 collections 类中的值，例如 pokemonoId pokemonName等等！

帮助我度过难关！

第一个问题（可能只是您在此处格式化的问题，但为了完整起见，我应该提到它）是您有：

Public ClassPokemonster

但正确的语法是：

public class Pokemonster

接下来，请注意您的所有其他类都被声明为在类Pokemonster。这种结构称为nested type。按照您的设计方式，Pokemonster 类本身不包含属性或方法，但嵌套类 Pokemonster.RootObject、Pokemonster.Pokemon 等确实具有属性。所以为了正确反序列化这种类型，你必须使用：

Pokemonster.RootObject deserializedObjects = 
    JsonConvert.DeserializeObject<Pokemonster.RootObject>(result);

最后，请注意属性Pokemonster.RootObject.Collections 实际上具有List<Pokemonster.Collection> 类型，但List<T> 没有任何名为PokemonId 的属性（因此出现错误消息）。您必须访问此列表中的项目才能获取它的任何属性，如下所示：

Assert.Equal("2310", deserializedObject.Collections[0].PokemonId.ToString());
