JSON.net-将嵌套对象反序列化为单个列表 [英] JSON.net - Deserialising nested objects to single list
本文介绍了JSON.net-将嵌套对象反序列化为单个列表的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试使用JSON.net反序列化对C#对象的JSON响应.
我在将嵌套对象转换为C#列表时遇到问题.
我在下面得到了JSON响应.
我想将所有variants下的节点放在C#中的单个List<Variant>中.
如何编辑我的反序列化器，以便可以对其进行反序列化?
I am trying to deserialising a JSON response to C# objects using JSON.net.
I am having issues with converting nested objects to a C# list.
I get the JSON response below.
I want to put all the nodes under variants in a single List<Variant> in C#.
How can I edit my deserialiser so that it can be properly deserialised?

推荐答案
您可以采用的一种方法是将JSON .Parse()转换为dynamic对象.
One approach you could take is to .Parse() the JSON into a dynamic object.
例如:
string jsonString = @"Your JSON String";
dynamic parsedJson = JValue.Parse(jsonString);
之后，您应该可以使用LINQ遍历dynamic对象并提取Variant
After that, you should be able to use LINQ to traverse through the dynamic object and extract your Variant
