JSON使用Newtonsoft解析子项目VB.NET

Question

我整个周末都一直在与我战斗。我正在尝试使用newtonsoft工具来解析/应对我的JSON。

我能够在没有麻烦的情况下到达顶级数据(EventID和EventName(。

我一直在搜寻示例和其他帖子，以帮助您在信息中获取信息。房间和会议将在JSON集合中有0个数量的物品。

我的JSON：

{
    "EventID": 123,
    "EventName": "Training Camp",
    "Rooms": [
        {
            "RoomID": 12,
            "RoomName": "Main Ballroom"
        },
        {
            "RoomID": 256,
            "RoomName": "East Hall"
        }
    ],
    "Sessions": [
        {
            "SessName": "Session One",
            "ScheduleID": 1682,
        },
        {
            "SessName": "Session Two",
            "ScheduleID": 1683,
        }
    ]
}

我的代码：

Public Class JSONEvent
    Public EventID As Integer
        Public EventName As String
        Public RoomsArray As List(Of JSONRooms)
End Class
Public Class JSONRooms
    Public Property RoomName As String
    Public Property RoomID As String
End Class

form1：

Dim obj = JsonConvert.DeserializeObject(Of JSONEvent)(JsonData)
messagebox.show(obj.eventid)
messagebox.show(obj.eventname)
Dim TheEvent As JSONEvent = JsonConvert.DeserializeObject(Of JSONEvent)(JsonData)
TheEvent.RoomsArray = JsonConvert.DeserializeObject(Of List(Of JSONRooms))(TheEvent.roomname) 'this I can't get right

有人可以帮助我访问这些数据元素吗？

任何帮助都非常感谢。

预先感谢您。

和c＃

中

[Serializable]
public class Room
{
    public int RoomID { get; set; }
    public string RoomName { get; set; }
}
[Serializable]
public class Session
{
    public string SessName { get; set; }
    public int ScheduleID { get; set; }
}
[Serializable]
public class JSONEvent
{
    public string EventID { get; set; }
    public string EventName { get; set; }
    public List<Room> Rooms { get; set; }
    public List<Session> Sessions { get; set; }
}

    // your code should work except the whole object should be deserialized at once.   

        JSONEvent obj = JsonConvert.DeserializeObject<JSONEvent>(JsonData);
        messagebox.show(obj.EventID);
        messagebox.show(obj.EventName);
        // check the array
        if(obj.Rooms != null && obj.Rooms.Count > 0)
        {
            messagebox.show(obj.Rooms[0].RoomID.ToString());
            messagebox.show(obj.Rooms[0].RoomName):
        }
