JsonUtility 读取 Json

JsonUtility.FromJson 方法只能接受 json 对象，需要标记[System.Serializable] 属性！！！

举例：

[Serializable]
public class DefaultCfgData
{
    public string gameName;
    public string version;
    public bool isStereo;
    public bool isUseHardWare;
    public refencenes[] statusList = new refencenes[] { };
}

[Serializable]
public class refencenes
{
    public string name;
    public int id;
}
