将JSON解析为对象数组

Question

我有以下序列化的类：

[System.Serializable]
public class Question
{
    public string question;
    public List<string> answers;
    public string correct;

    public Question(string question, List<string> answers, string correct){
        this.question = question;
        this.answers = answers;
        this.correct = correct;
    }
}

以及以下questions数组：

questions = new List<GameManager.Question>();
questions.Add(new GameManager.Question("2+2?", new List<string> { "4", "5", "6" }, "4"));
questions.Add(new GameManager.Question("2*2?", new List<string> { "1", "4", "8" }, "4"));
questions.Add(new GameManager.Question("2/2?", new List<string> { "0", "1", "2" }, "1"));

我需要以json格式存储此信息，并将其加载以启动问题游戏。

如何使用json加载一系列问题？

Answer 1

您可以使用newtonsoft.json对对象进行序列化和反序列化。使用非常简单。我认为您必须安装nuget软件包。

Answer 2

这是一个可行的例子

void Main()
{
    var questions = new List<Question>();
    questions.Add(new Question("2+2?", new List<string> { "4", "5", "6" }, "4"));
    questions.Add(new Question("2*2?", new List<string> { "1", "4", "8" }, "4"));
    questions.Add(new Question("2/2?", new List<string> { "0", "1", "2" }, "1"));

    var json = JsonConvert.SerializeObject(questions, Newtonsoft.Json.Formatting.Indented);
    Console.WriteLine(json);
}

// Define other methods and classes here
public class Question
{
    public string question;
    public List<string> answers;
    public string correct;

    public Question(string question, List<string> answers, string correct)
    {
        this.question = question;
        this.answers = answers;
        this.correct = correct;
    }
}

输出

[
  {
    "question": "2+2?",
    "answers": [
      "4",
      "5",
      "6"
    ],
    "correct": "4"
  },
  {
    "question": "2*2?",
    "answers": [
      "1",
      "4",
      "8"
    ],
    "correct": "4"
  },
  {
    "question": "2/2?",
    "answers": [
      "0",
      "1",
      "2"
    ],
    "correct": "1"
  }
]

您可以通过

将其反序列化为一系列问题

var deserialized = JsonConvert.DeserializeObject<Question[]>(json);

如果已安装NewtonSoft.Json.JsonConvert.SerializeObject，则可以使用Newtonsoft.Json.JsonConvert.DeserializeObject<T>和nuget package。然后只需用JsonProperty标签，文档（https://www.newtonsoft.com/json/help/html/SerializingJSON.htm）装饰您的媒体资源
