C#帮处理一下JSON获取最大值

langbin

{"34520942":"1.30","8317742":"1.30","8873077":"1.30","7341290":"1.30","32691694":"1.30","9564889":"1.30","11358434":"30.30","34605766":"1.30","33695385":"1.30"}这些数字是会变的。每次取最高值的那比如这里最高值是 "11358434":"30.30"那就取出11358434

可以试着转换成字典对象，然后取key值集合  筛选出最大值

string s = "[{\"34520942\":\"1.30\",\"8317742\":\"1.30\",\"8873077\":\"1.50\",\"7341290\":\"1.30\",\"32691694\":\"1.30\",\"9564889\":\"1.30\",\"11358434\":\"30.30\",\"34605766\":\"1.30\",\"33695385\":\"1.30\"}]";
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            var dic = serializer.Deserialize<Dictionary<string, float>[]>(s)[0];
            string key = dic.OrderByDescending(kvp => kvp.Value).First().Key;

应该是这样更好，上面的多加了一个括号
