如何方便地使用 C# 取出 JSON 中的某个值？

{"images":[{"startdate":"20160804","fullstartdate":"201608041600","enddate":"20160805","url":"http://s.cn.bing.net/az/hprichbg/rb/MaracanaFireworks_ZH-CN9834580695_1920x1080.jpg","urlbase":"/az/hprichbg/rb/MaracanaFireworks_ZH-CN9834580695","copyright":"马拉卡纳体育场上空绽放的礼花，巴西里约热内卢 (?

比如这一段 JSON ，我想把其中 http://s.cn.bing.net/az/hprichbg/rb/MaracanaFireworks_ZH-CN9834580695_1920x1080.jpg 这段数据给取出来，应该怎么做？

json反序列化已经很简单了，对于正则，虽然也很简单，但比较容易出问题

反序列化出来，通过实体类取

楼上正解

正则试试，

Regex.Match(s, "\"url\":.*?\"(.*)\"").Groups[1].Value

[xuzuning]

var o = JObject.Parse(json);
var v = o["images"][0]["url"];

能取出就行了,不要途"方便".
