Question

最初我的json是格式，

"code": 0,
"message": "success",
"students": [
    {
        "id": "257633000000070001",
        "name": "hjeke",
        "percentage": 36,
        "type": "Good",
    },
    {
        "id": "257633000000073001",
        "name": "Second",
        "percentage": 4,
        "type": "bad",
    }]

因此我使用以下类使用Newtonsoft.json进行反序列化

[DataContract]
public class students
{
    [DataMember(Name = "code")]
    public int Code { get; set; }

    [DataMember(Name = "message")]
    public string Message { get; set; }

    [DataMember(Name = "students")]
    public StudentDetail StudentDetail { get; set; }
}
[DataContract]
public class StudentDetail 
{
    [DataMember(Name = "id")]
    public string ID { get; set; }

    [DataMember(Name = "name")]
    public string Name { get; set; }

    [DataMember(Name = "percentage")]
    public double PercentageForEdit { get; set; }

    [DataMember(Name = "type")]
    public string Type { get; set; }
}

但现在我的json改为了，

"code": 0,
"message": "success",
"students": {
    "details":{
        "hjeke": {
            "id": "257633000000070001",
            "name": "hjeke",
            "percentage": 36,
            "type": "Good",
        },
        "Second": {
            "id": "257633000000073001",
            "name": "Second",
            "percentage": 4,
            "type": "bad",
        }
      }
  }

我应该如何更改学生课程，

  StudentDetails = JsonConvert.DeserializeObject<Students>(data);

Answer 1

如果您使用Newtonsoft.Json，请尝试使用该类：

public class StudentDetails
{
    public string id { get; set; }
    public string name { get; set; }
    public int percentage { get; set; }
    public string type { get; set; }
}

public class Student
{
    public int code { get; set; }
    public string message { get; set; }
    public List<StudentDetails> students { get; set; }
}

之后，您可以使用该类通过以下方式反序列化响应：

var parsedResponse = JsonConvert.DeserializeObject<Student>(data);

P.S。当然，不要忘记[DataContract]和[DataMember]属性

首先你的Json似乎没有效果，对象{}缺少周围的括号。要找到匹配的C＃类，有一个很好的转换器on this site

对于你的第二个带有对象括号的Json：

"code": 0,
"message": "success",
"students": {
"details":{
    "hjeke": {
        "id": "257633000000070001",
        "name": "hjeke",
        "percentage": 36,
        "type": "Good",
    },
    "Second": {
        "id": "257633000000073001",
        "name": "Second",
        "percentage": 4,
        "type": "bad",
    }
  }
}

它建议这些课程：

public class Hjeke
{
  public string id { get; set; }
  public string name { get; set; }
  public int percentage { get; set; }
  public string type { get; set; }
}

public class Second
{
  public string id { get; set; }
  public string name { get; set; }
  public int percentage { get; set; }
  public string type { get; set; }
}

public class Details
{
  public Hjeke hjeke { get; set; }
  public Second Second { get; set; }
}

public class Students
{
  public Details details { get; set; }
}

public class RootObject
{
  public int code { get; set; }
  public string message { get; set; }
  public Students students { get; set; }
}

您可以自己使用这个生成器工具。
