将复杂的json转换为c#类

Por*_*ter 4 c# json json.net

我一直在尝试使用来自此网站和其他网站的类似问题的帮助,将以下json数据反序列化为2天,并且可能会使脑死亡.

我有这个json数据(长度道歉)并且我正在尝试,作为开始在'Values'数组中获得'value'数字: -

我使用http://json2csharp.com/创建了类,并尝试过以下方法: -

RootObject ro = JsonConvert.DeserializeObject<RootObject>(json_data);

这是一个有效的dotNet小提琴,可以对ValuesList进行反序列化.https://dotnetfiddle.net/7P2em6

加载小提琴时等待几秒钟,并在控制台窗口中注意输出.代码应该是不言自明的,但如果您需要帮助,请告诉我.

我还在下面粘贴了它,以防万一dotNetFiddle不可用.

控制台输出:

将复杂的json反序列化为c#类

我使用http://json2csharp.com/从JSON字符串生成类.

我认为你的问题可能Values是List在Row对象内部,而对象List内部则是RootObject.换句话说,Values被存储为List内部a List.

注意:对于columns对象,您不需要单独的字段类(json2csharp.com类生成器将默认为该类).您可以将值存储columns在字典类中的对象中(如果您知道它们的名称将是唯一的).对于它的实现(不同的JSON字符串,但相同的json模式类型,原则),请看这个小提琴:https://dotnetfiddle.net/7bFcNM
