unity中如何从json获取数组？

Question

我得到了一个统一的json str：

{"action":"result","code":"0","data":"{\"seg_id\":2,\"cn\":{\"st\":{\"rt\":[{\"ws\":[{\"cw\":[{\"sc\":0.00,\"w\":\"今天\",\"wp\":\"n\",\"rl\":\"0\",\"wb\":9,\"wc\":0.00,\"we\":52}],\"wb\":9,\"we\":52},{\"cw\":[{\"sc\":0.00,\"w\":\"天气\",\"wp\":\"n\",\"rl\":\"0\",\"wb\":53,\"wc\":0.00,\"we\":92}],\"wb\":53,\"we\":92},{\"cw\":[{\"sc\":0.00,\"w\":\"怎么样\",\"wp\":\"n\",\"rl\":\"0\",\"wb\":93,\"wc\":0.00,\"we\":156}],\"wb\":93,\"we\":156},{\"cw\":[{\"sc\":0.00,\"w\":\"？\",\"wp\":\"p\",\"rl\":\"0\",\"wb\":156,\"wc\":0.00,\"we\":156}],\"wb\":156,\"we\":156}]}],\"bg\":\"160\",\"type\":\"0\",\"ed\":\"1900\"}},\"ls\":true}","desc":"success","sid":"rta02434f94@dx5bb219816a261aba00"}

我创建类，使用

JsonUtility.fromJson

来解析它。

public class JsonData
{
    public string action;

    public string code;

    public Data data;

    public string desc;

    public string sid;
}

[Serializable]
public class Data
{
    public string seg_id;
    [Serializable]
    public class CN
    {
        [Serializable]
        public class ST
        {
            [Serializable]
            public class RT
            {
                [Serializable]
                public class WS
                {
                    [Serializable]
                    public class CW
                    {
                        public string w;
                        public string wp;
                    }

                    public CW[] cw;
                    public string wb;
                    public string we;
                }

                public WS[] ws;
            }
            public RT rt;
            public string bg;
            public string type;
            public string ed;
        }

        public ST st;
    }
    public CN cn;
    public string ls;
}

但结果却是空的。 我使用

JsonUtility.toJson

，它无法获取任何数据值。 但是，我想获取json中的值

w

，我该如何获取它？

我测试了其他方法，但仍然可以解析它。

我看到 Json 没有格式化，我进行了修复。我用 Json 生成了 C# 文件，发现我可以获取其中的数组值。我使用 Newtonsoft 程序集将 Json 反序列化为类。进行更改后，我可以看到 w 属性中填充的值，如下所示

请找到用于将 Json 反序列化为 C# 类的类文件。

public class Cn
{
    public St st { get; set; }
}

public class Cw
{
    public double sc { get; set; }
    public string w { get; set; }
    public string wp { get; set; }
    public string rl { get; set; }
    public int wb { get; set; }
    public double wc { get; set; }
    public int we { get; set; }
}

public class Data
{
    public int seg_id { get; set; }
    public Cn cn { get; set; }
    public bool ls { get; set; }
}

public class JsonData
{
    public string action { get; set; }
    public string code { get; set; }
    public Data data { get; set; }
    public string desc { get; set; }
    public string sid { get; set; }
}

public class Rt
{
    public List<W> ws { get; set; }
}

public class St
{
    public List<Rt> rt { get; set; }
    public string bg { get; set; }
    public string type { get; set; }
    public string ed { get; set; }
}

public class W
{
    public List<Cw> cw { get; set; }
    public int wb { get; set; }
    public int we { get; set; }
}

请找到将Json反序列化为C#类文件的代码
