将JSON解析为对象数组[重复]

unity3d json c#

这个问题已经有了答案:

Serialize and Deserialize Json and Json Array in Unity 6个答案

我有以下序列化类:

[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;
    }
}

以及以下数组 questions :

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"));

我需要将此信息存储为 json 格式化并加载它以初始化问题游戏。

如何使用JSON加载一组问题?

可以使用newtonsoft.json对对象进行序列化和反序列化。它很容易使用。我想你必须安装Nuget软件包。

以下是关于如何在Unity 3D中序列化和保存数据的文章: Post

这是一个有效的例子

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;
    }
}

产量

[
  {
    "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"
  }
]

您可以通过以下方式将其反序列化回问题集合:

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

你可以用 NewtonSoft.Json.JsonConvert.SerializeObject 和 Newtonsoft.Json.JsonConvert.DeserializeObject<T> 如果你有那个 nuget package 安装。然后用一个 JsonProperty 标签、文件( https://www.newtonsoft.com/json/help/html/SerializingJSON.htm )
