推荐答案

一般来说，你必须反序列化这个json字符串。 你有几种方法（ datacontract serializer [ ^ ]，fastjson [ ^ ]， json [ ^ ] ...），以及 LINQ to Json [ ^ ]是一个很好的方法。 这样的东西： In general you would have to deserialize this json string. You have several methods (datacontract serializer[^], fastjson[^], json[^]...), and LINQ to Json[^] is a nice approach. Something like this: Newtonsoft.Json.Linq.JObject o = Newtonsoft.Json.Linq.JObject.Parse(@"{ //your json here "); var users = o["reviews"].Select(x => x["user"]); }

在谷歌上花了一些时间我会找到符合条件的结果 after spend some time on google i''ll find eligible result var jsonSerialization1 = new JavaScriptSerializer(); var dictObj1 = jsonSerialization1.Deserialize<Dictionary<string, dynamic>>(mainstring.Replace("/", "")); string suser_image_url = dictObj1["reviews"][i]["user"]["image_url"]; string suser_id = dictObj1["reviews"][i]["user"]["id"]; string suser_name = dictObj1["reviews"][i]["user"]["name"];

希望这个也会帮助你 有一个美好的一天

hope this will help you too have a good day
