Question

可以帮我如何在C＃中创建Json文件，如下面的示例所示？我有中心列表，房间内部和内部的房间列表是预订列表（预订日期是预订的要素之一）。我不知道如何从列表中创建此数据结构。

"data": [
{
  "meetingCentre": "EBC-MC_C7",
  "meetingRoom": "EBC-C7-MR:1_1",
  "reservations": {
    "28.10.2016": [
      {
        "from": "10:00",
        "to": "11:30",
        "expectedPersonsCount": 4,
        "customer": "College",
        "videoConference": false,
        "note": ""
      },
      {
        "from": "12:00",
        "to": "13:30",
        "expectedPersonsCount": 4,
        "customer": "College",
        "videoConference": false,
        "note": ""
      }
    ],
    "29.10.2016": [
      {
        "from": "10:00",
        "to": "11:30",
        "expectedPersonsCount": 4,
        "customer": "College",
        "videoConference": false,
        "note": ""
      }
    ]
  }
},
....

实际上，我认为这取决于用例是什么。如果要将其用作DTO，则应考虑使用词典进行预订收集。

// Component
export class LandingYoutubeComponent implements OnInit {

      constructor(private youtube: YoutubeService) { 
      }

      ngOnInit() {
        this.youtube.getVideos().subscribe(data => console.log(data));
      }
    }

// Service
export class YoutubeService {

  videoSubscription: Observable<any>;
  API_KEY: string = 'someKey';
  CHANNEL_ID: string = 'someID';
  configUrl: string = `https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=${this.CHANNEL_ID}&maxResults=50&order=date&type=video&key=${this.API_KEY}`

  constructor(private http: HttpClient) {
    this.videoSubscription = this.http.get(this.configUrl);  //  create observable for external subscriptions
  }

  getVideos() {
    return this.videoSubscription;
  }
}

要填充此对象（如果您正在使用asp.net/core），则应阅读有关ModelBinders https://docs.microsoft.com/pl-pl/aspnet/core/mvc/models/model-binding?view=aspnetcore-2.2的信息。

也许您可以利用Newtonsoft.JSonConvert吗？

我的结构有点简化（例如，用字符串代替日期），但是如果您检查生成的json，它就可以满足您的需求。

public class Class1
  {

    static void Main()
    {



      meetingCentre myCenter = new meetingCentre("EBC-MC_C7");
      meetingRoom myRoom = new meetingRoom("EBC-C7-MR:1_1");
      myCenter.rooms.Add(myRoom);
      myRoom.reservations.Add(new reservation("28.10.2016", "10:00", "11:30", 4, "College", false, ""));
      myRoom.reservations.Add(new reservation("28.10.2016", "12:00", "13:30", 4, "College", false, ""));
      myRoom.reservations.Add(new reservation("29.10.2016", "10:00", "11:30", 4, "College", false, ""));

      Console.WriteLine(JsonConvert.SerializeObject(myCenter, Formatting.Indented));






      Console.ReadLine();
    }

  }


  public class meetingCentre
    {

      public List<meetingRoom> rooms = new List<meetingRoom>();

      public string id;

      public meetingCentre(string id)
      {
        this.id = id;
      }
    }

    public class meetingRoom
    {
      public List<reservation> reservations = new List<reservation>();
      public string id;

      public meetingRoom(string id)
      {
        this.id = id;
      }
    }

    public class reservation
    {

      public reservation(string d, string f, string t, int pc, string cust, bool v, string n)
      {
        date = d;
        from = f;
        to = t;
        expectedPersonsCount = pc;
        customer = cust;
        videoConference = v;
        note = n;

      }
      public string date { get; set; }
      public string from { get; set; }
      public string to { get; set; }
      public int expectedPersonsCount { get; set; }
      public string customer { get; set; }

      public bool videoConference { get; set; }
      public string note { get; set; }

    }

}
