请问用 Newtonsoft.Json 如何解析如下JSON字符串各属性的值？
如：serial_number ?
field_1?
created_at ? (时间)
谢谢，求大神
这样的JSON字符串没有[] 包起来，仔细看看，还是不知道怎么解析,希望方便的话提供一个源码DEMO
{
"form": "RTPppE",
"entry": {
"serial_number": 22,
"field_1": "2014-09-25",
"field_13": "华东区",
"field_14": "xxxx",
"field_15": "xxxxxx",
"field_16": 1,
"field_17": 0,
"field_18": 698,
"field_19": "",
"x_field_weixin_nickname": "",
"x_field_weixin_gender": "",
"x_field_weixin_country": "",
"x_field_weixin_province_city": {},
"x_field_weixin_openid": "oFBGBx6kdOI",
"x_field_weixin_headimgurl": "",
"creator_name": "",
"created_at": "2014-09-25T04:06:07Z",
"updated_at": "2014-09-25T04:06:07Z"
}
}

"form": "TyGOun",
"entry": {
"serial_number": 10,
"field_21": "销售",
"field_22": "2014-09-25",
"field_23": {
"level_1": "xxxx",
"level_2": " 01000"
},
"field_24": 1,
"field_25": 798,
"field_26": "",
"field_27": "",
"x_field_weixin_nickname": "",
"x_field_weixin_gender": "",
"x_field_weixin_country": "",
"x_field_weixin_province_city": {},
"x_field_weixin_openid": "",
"x_field_weixin_headimgurl": "",
"creator_name": "",
"created_at": "2014-09-25T07:13:06Z",
"updated_at": "2014-09-25T07:13:06Z"
}
}

创建一个类 Test 属性form 属性entry 对象

entry对象：属性serial_number 属性...

就是这个样子，根据需求来进行解析

javascript 解析用 var data = eval(json) ; 数组 c#解析用： using system.web.extensions; using system.web.script.serialization; public object fromjson(string json) { javascriptserializer js = new javascriptserializer(); return js.deserialize(json); }

你加一个 [], 包起来不就能解析成 List 了 ///

/// 转换为JSON字符串 ///

public static string JsonSerializeByNewton(T obj) { if (obj == null) return ""; StringWriter sw = new StringWriter(System.Globalization.CultureInfo.InvariantCulture); Newtonsoft.Json.JsonSerializer json = new Newtonsoft.Json.JsonSerializer(); json.NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore; json.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore; using (Newtonsoft.Json.JsonWriter jw = new Newtonsoft.Json.JsonTextWriter(sw)) { json.Serialize(jw, obj); } return sw.ToString(); } public static T JsonDeserializeByNewton(string jsonStr) where T : class { Newtonsoft.Json.JsonSerializer jSeri = new Newtonsoft.Json.JsonSerializer(); using (StringReader sr = new StringReader(jsonStr)) { return (T)jSeri.Deserialize(sr, typeof(T)); } }
