Question

renderReverse&&renderReverse({"status":0,"result":{"location":{"lng":118.24691803795,"lat":35.502509941703},"formatted_address":"山东省临沂市沂南县","business":"","addressComponent":{"city":"临沂市","country":"中国","direction":"","distance":"","district":"沂南县","province":"山东省","street":"","street_number":"","country_code":0},"pois":[{"addr":"临沂市沂南县","cp":"NavInfo","direction":"东南","distance":"830","name":"安乐庄村","poiType":"行政地标","point":{"x":118.24266069864,"y":35.507519566229可能是电话号码，是否拨号?},"tag":"行政地标;村庄","tel":"","uid":"251374c990ccfe3ea01de9a9","zip":""}],"poiRegions":[],"sematic_description":"安乐庄村东南830米","cityCode":234}})

如上是返回的一次json数据，C# 语言，怎么提取特定的值，比如从"district":"沂南县"中提取城市名，沂南县，怎么处理

Answer 1

安装json.net控件,并using Newtonsoft.Json.Linq;
这样就可以获取想要的tag对应的内容了。
