unity 字符串转json格式问题

{"type":"WeatherRMessage","code":200,"payload":{"temperature":"23°C","windDirection":"东南风","windGrade":"61级"}}

用litjson解析这个字符串。ss就是图1打印的字符串。

public class Payload
{
    /// <summary>
    /// 
    /// </summary>
    public string temperature { get; set; }
    /// <summary>
    /// 东南风
    /// </summary>
    public string windDirection { get; set; }
    /// <summary>
    /// 61级
    /// </summary>
    public string windGrade { get; set; }
}
 
public class Root
{
    /// <summary>
    /// 
    /// </summary>
    public string type { get; set; }
    /// <summary>
    /// 
    /// </summary>
    public int code { get; set; }
    /// <summary>
    /// 
    /// </summary>
    public Payload payload { get; set; }
}

用json工具转成Root类型就可以随便用了。
