如何在c＃中请求后更改json格式？

Question

我在PostMan中发送这样的Json格式

    {
  "number": 2106887,
  "date": "09/10/2018",
  "degree":"BE"
  "Students": [
    {
      "Branch": "ABK015",
      "Doc": "NCE",
      "Description": "Testing",
      "dni": "1016035232",
      "Name": "ABCE",
      "Gender": "M",
      "Title": "Univercity",
      "email": "abc@in.com",
    },
    {
      "Branch": "ABK016",
      "Doc": "NCE",
      "Description": "Testing1",
      "dni": "1016035233",
      "Name": "ABCE",
      "Gender": "M",
      "Title": "Univercity",
      "email": "abcd@in.com",
    }
  ]
}

在控制器级别，我正在对所有字段进行验证。 验证后如何将上述json字符串转换为以下格式

{

  "Students": [
    {
      "number": 2106887,
      "date": "09/10/2018",
      "degree":"BE"
      "Branch": "ABK015",
      "Doc": "NCE",
      "Description": "Testing",
      "dni": "1016035232",
      "Name": "ABCE",
      "Gender": "M",
      "Title": "Univercity",
      "email": "abc@in.com",
    },
    {
      "number": 2106887,
      "date": "09/10/2018",
      "degree":"BE"
      "Branch": "ABK016",
      "Doc": "NCE",
      "Description": "Testing1",
      "dni": "1016035233",
      "Name": "ABCE",
      "Gender": "M",
      "Title": "Univercity",
      "email": "abcd@in.com",
    }
  ]
}

和aftre转换，我想插入数据库。 如何转换c＃？ 请帮我。

以下代码是学生的课程：

public class Students
{
    [Required]
    public string Branch{ get; set; }
    [Required]
    public string Doc{ get; set; }
    [Required]
    public string Description{ get; set; }
    [Required]
    public string dni{ get; set; }
    [Required]
    public string Name{ get; set; }
    [Required]
    public string Gender{ get; set; }
    [Required]
    public string Title{ get; set; }
    [Required]
    public string email{ get; set; }
    [Required]
    public string degree{ get; set; }
    [Required]
    public string date{ get; set; }
    [Required]
    public string number{ get; set; }
}

我在这里反序列化

var requestBody = requestContent.Content.ReadAsStringAsync().Result;
            JObject jxxx = JsonConvert.DeserializeObject<dynamic>(requestBody);

请参阅更新的代码

Answer 1

您可以使用DeserializeAnonymousType方法。 首先创建一个template对象

var template = new {number = "", date = "", degree = "", Students = new Students[0]};

现在反序列化为临时json对象：

var jsonObject = JsonConvert.DeserializeAnonymousType(input, template);

在此之后，您可以将信息从json标题复制到带有linq的Students ：

var students = jsonObject.Students.Select(s =>
{
    s.number = jsonObject.number;
    s.date = jsonObject.date;
    s.degree = jsonObject.degree;
    return s;
}).ToArray();

另请注意，您的输入JSON无效：它缺少逗号afetr degree值。

Answer 2

"Students": [
    {
      "number": 2106887,
      "date": "09/10/2018",
      "degree":"BE"
      "Branch": "ABK015",
      "Doc": "NCE",
      "Description": "Testing",
      "dni": "1016035232",
      "Name": "ABCE",
      "Gender": "M",
      "Title": "Univercity",
      "email": "abc@in.com",
    },
    {
      "number": 2106887,
      "date": "09/10/2018",
      "degree":"BE"
      "Branch": "ABK016",
      "Doc": "NCE",
      "Description": "Testing1",
      "dni": "1016035233",
      "Name": "ABCE",
      "Gender": "M",
      "Title": "Univercity",
      "email": "abcd@in.com",
    }
  ]

然后尝试这个

var students = JsonConvert.DeserializeObject<Students[]>(requestBody);
