使用C#读取ASP.NET中的Json文件

Question

我有一个 JSON 文件，请告诉我如何读取该文件。我创建了一个类文件，想要在这些类属性中保存 JSON 数据。

        }
      ]
    }
  ]
}

我正在使用以下代码读取JSON，如何读取JSON的节点？

我想读取JSON文件中的所有节点。我已经创建了所有节点的属性，同时将房间类型保存在列表中。

这是我班级中的代码：

 public class Body
    {
        public List<Hotelbooking> hotelbooking { get; set; }
        public string customerId { get; set; }
        public string paymentbank { get; set; }
        public string secdeposit { get; set; }
        public List<OtherInfo> OtherInfo { get; set; }
    }
 public class Bookings
{
    public Profile Profile { get; set; }
    public string roomtype { get; set; }
}

public class BookingStatus
{
    public Confirm Confirm { get; set; }
    public string Pax { get; set; }
    public string currency { get; set; }
    public DateTime bookDateTime { get; set; }
    public string address { get; set; }
    public string days { get; set; }
    public string paymentstatus { get; set; }
}

public class Confirm
{
    public int amount { get; set; }
}

public class Customer
{
    public Bookings Bookings { get; set; }
}

public class Header
{
    public string hid { get; set; }
    public string datestamp { get; set; }
}

public class Hotelbooking
{
    public Customer Customer { get; set; }
    public BookingStatus BookingStatus { get; set; }
    public RoomDetails RoomDetails { get; set; }
    public string paymentmode { get; set; }
    public string creditcardNumber { get; set; }
    public string paymentRef { get; set; }
}

public class OtherInfo
{
    public string ExtraBed { get; set; }
    public string Breakfast { get; set; }
    public string RefNo { get; set; }
}

public class Profile
{
    public string name { get; set; }
    public string dob { get; set; }
    public string mobile { get; set; }
    public string address { get; set; }
    public string email { get; set; }
    public string id { get; set; }
}

public class Room
{
    public string roomtype { get; set; }
    public int pricepernight { get; set; }
    public string currency { get; set; }
    public string refid { get; set; }
}

public class RoomDetails
{
    public List<Room> Rooms { get; set; }
    public string bookstartDate { get; set; }
    public string bookendDate { get; set; }
}

这是我读取 JSON 文件的代码：

 string jsonFile = @"E:\hotel.json";
    var json = File.ReadAllText(jsonFile);

    var jsonObject = JObject.Parse(json);
JArray hotelbodyArrary = (JArray)jsonObject["body"];

if (hotelbodyArrary != null)
{
    Body body = new Body();
    Hotelbooking ho = new Hotelbooking();
    foreach (var item in hotelbodyArrary)
    {
        
        ho.paymentmode = Convert.ToString(item["paymentmode"]);
        ho.creditcardNumber = Convert.ToString(item["creditcardNumber"]);
    }

}

我没有得到任何价值

Answer 1

您的

body

数组由多个带有

hotelbooking

数组的对象组成。您需要迭代

hotelbooking

数组中的每个对象以获得

paymentmode

和

creditcardNumber

值。

Body body = new Body();
body.hotelbooking = new List<Hotelbooking>();

Hotelbooking ho = new Hotelbooking();
foreach (var item in hotelbodyArrary)
{
    JArray hotelBookingJArray = JArray.FromObject(item["hotelbooking"]);
    foreach (var hotelJObj in hotelBookingJArray)
    {
        ho.paymentmode = Convert.ToString(hotelJObj["paymentmode"]);
        ho.creditcardNumber = Convert.ToString(hotelJObj["creditcardNumber"]);

        body.hotelbooking.Add(ho);
    }
}

这将使将其反序列化为类变得更容易，并且您会错过

Root

类。

Root root = JsonConvert.DeserializeObject<Root>(json);

public class Root
{
    [JsonProperty("header")]
    public Header Header { get; set; }

    [JsonProperty("body")]
    public List<Body> Body { get; set; }
}
