推荐答案

最简单的解决方案是使用Visual Studio 编辑>选择性粘贴>将Json粘贴为类. 但是由于您的json是不同对象的数组，因此.NET类将只是

The easiest solution is to use Visual Studio Edit > Paste Special > Paste Json As Classes. But as your json is an array of different objects the .NET class will just be

public class JsonDto
{
    public List<object> Results { get; set; }
}

使用对象列表会很麻烦，因此我建议您使用类型化的模型，但是随后您需要指定需要定义的值，这是一个示例

A list of objects will be painful to work with so I recommend that you to use a typed model but then you need to specify you need to define the values, here's an example

{"results": [
     {
       "key1":"43853",
       "key2":"43855",
       "key3":"43856",
       "key4":"43857",
       "question": {
         "questionType": 3,
         "choiceAnswers": [123]   
       }
     }
 ]};

 public class JsonDto
 {
    public List<ResultDto> Results { get; set; }
 }
 public class ResultDto
 {
    public string Key1 { get; set; }
    public string Key2 { get; set; }
    public string Key3 { get; set; }
    public string Key4 { get; set; }
    public QuestionDto Question { get; set; }
 }
 public class QuestionDto
 {
    public int QuestionType { get; set; }
    public List<int> ChoiceAnswers { get; set; }
 }
