在C#中将根元素添加到json序列化

我正在创建一个与JSON API交互的Web服务。

这个API需要我在字符串中设置一个根元素,但我不能让它发生。

这一切发生的地方 - 现在只是向我展示json输出:

public static string CreateServiceChange(ServiceChange change)
        {
            string json = JsonConvert.SerializeObject(change);

            return json;
        }

这是ServiceChange类:

public class ServiceChange
{
    [JsonProperty("email")]
    public string requesterEmail { get; set; }

    [JsonProperty("description_html")]
    public string descriptionHtml { get; set; }

    [JsonProperty("subject")]
    public string subject { get; set; }

    [JsonProperty("change_type")]
    public int changeType { get; set; }
}

将这两者结合在一起的方法:

    public string copyTicketToChange(int ticketId)
    {
        HelpdeskTicket.TicketResponseActual ticket = getHelpdeskTicket(ticketId);
        ServiceChange change = new ServiceChange();
        change.descriptionHtml = ticket.Response.DescriptionHtml;
        change.requesterEmail = ticket.Response.Email;
        change.subject = ticket.Response.Subject;
        change.changeType = 1;
        string Response = Dal.CreateServiceChange(change);
        return Response;
    }

json输出现在看起来像这样:

{"email":"test@test.com","description_html":"This is a test","subject":"Testing","change_type":1}

预期的产出:

{ "itil_change": {"email":"test@test.com","description_html":"This is a test","subject":"Testing","change_type":1}}

我怎样才能做到这一点?

答案 0 :(得分:1)

将ServiceChange包装到另一个对象并序列化:

  public class ServiceChangeWrapper
  {
    public ServiceChange itil_change { get; set; }
  }

...

public static string CreateServiceChange(ServiceChange change)
    {
        ServiceChangeWrapper wrapper = new ServiceChangeWrapper { itil_change = change};
        string json = JsonConvert.SerializeObject(wrapper);

        return json;
    }
