各位大哥帮小弟看一下c#用newtonsoftJson怎么解析下面这段json

{
    "errNum": 0,
    "errMsg": "success",
    "retData": {
        "from": "en",
        "to": "zh",
        "dict_result": {
            "word_name": "hello",
            "symbols": [
                {
                    "ph_am": "hɛˈlo, hə-",
                    "ph_en": "hə'ləʊ",
                    "parts": [
                        {
                            "part": "int.",
                            "means": [
                                "哈喽，喂",
                                "你好，您好",
                                "表示问候",
                                "打招呼"
                            ]
                        },
                        {
                            "part": "n.",
                            "means": [
                                "“喂”的招呼声或问候声"
                            ]
                        },
                        {
                            "part": "vi.",
                            "means": [
                                "喊“喂”"
                            ]
                        }
                    ]
                }
            ]
        }
    }
}

我想把里面的那些解释的意思(means)提取出来，无奈是新手弄了半天没弄出来 请各位帮帮忙

建立好类后序列化就好了。。代码如下

     public class Parts { public System.Collections.Generic.List<string> means; }
    public class Symbols { public System.Collections.Generic.List<Parts> parts; }
    public class Dict_result { public System.Collections.Generic.List<Symbols> symbols;}
    public class RetData { public Dict_result dict_result;}
    public class Json { public RetData retData; }
    protected void Page_Load(object sender, EventArgs e)
    {
        string d = System.IO.File.ReadAllText(Server.MapPath("bb.txt"), Encoding.UTF8);//这里改为你获取到的字符串，测试将你的内容放入文件里面进行读取
        Json o = Newtonsoft.Json.JsonConvert.DeserializeObject(d, typeof(Json)) as Json;
        foreach(Symbols symbol in  o.retData.dict_result.symbols)
            foreach(Parts part in symbol.parts)
                foreach (string s in part.means) {
                    Response.Write(s + "<br>");
                }
    } 

不好意思再请教一下如果要把part也解析出来，那么在建类的时候应该怎么建呢？
