Unity JSON序列化程序不允许在JSON对象中调用JSON字段

问题是，我无法从一个被刮掉的网站调用嵌套的JSON对象。刮取过程工作得很好，但JSON序列化部分是唯一的问题。我的代码如下所示：

private void GetHtmlAsync()
    {
        var url = "https://opentdb.com/api.php?amount=10";

        var httpClient = new HttpClient();
        var html = httpClient.GetStringAsync(url);

        DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(MyDetail));
        MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(html.Result));
        stream.Position = 0;
        MyDetail dataContractDetail = (MyDetail) jsonSerializer.ReadObject(stream);
        text.text = "" + dataContractDetail.results[1];
        //text.text = string.Concat("Test: ", dataContractDetail.question, " " + dataContractDetail.correct_answer);
    }

    public class MyDetail
    {
        [DataMember]
        public Dictionary<string, questions> results
        {
            get;
            set;
        }

        public class questions
        {
            public string question { get; set; }
            public string correct_answer { get; set; }

        }

        [DataMember]
        public string response_code
        {
            get;
            set;
        }
    }

代码中有很多问题。我不知道你正在使用的所有库，但我会这样做

首先，启动一个

GetStringAsync

，但不等待结果立即继续。我不知道你使用的所有图书馆当然可能是这样的

然而，我宁愿使用统一的

同样，我不知道您的JSON库，但您的类似乎与JSON数据结构不匹配（通过简单地阻塞它）

然后，如注释中所述，注意c#中的数组索引是基于

0

，因此第一个元素是

var firstResult = dataContractDetail.results[0];

现在的问题是你想在你的文本上看到什么？

firstResult

不是

string

，而是一个包含各种成员的类！例如，您可能希望将问题显示为

text.text = firstResult.question;

---

因为我试图通过执行“results[1]”来调用results中的第一个对象（仅供参考），C#数组是基于零索引的，所以第一个结果将是0而不是1。（我认为这与你的问题无关。）结果json有10个对象，因此结果[8]和结果[0]应该会返回一个字符串。谢谢你详细而有用的回答！你真的为我节省了很多时间。我感谢你的帮助！！

...
MyDetail dataContractDetail = JsonUtility.FromJson<MyDetail>(json);

var firstResult = dataContractDetail.results[0];

text.text = firstResult.question;
