O365使用REST API创建事件

Question

I am trying to call this code

 string accessToken = @".."; //valid token with right scopes
 public string EventsUrl = @"https://outlook.office.com/api/v2.0/me/events";

 // generate body
 var postBody = JsonBody(invite);

 using (var client = new HttpClient())
 {
       using (var request = new HttpRequestMessage(HttpMethod.Post, EventsUrl))
        {
             request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
             var content = new StringContent(postBody, Encoding.UTF8, "application/json");

             request.Content = content;

             var response = await client.SendAsync(request);
             return (response.IsSuccessStatusCode);
         }
 }

The method that create JsonBody is,

public string JsonBody(User user, Session session){

        var invite = new EventInvite
        {
            Attendees = new Attendee[1]
        };

        invite.Attendees[0] = new Attendee
        {
            Type = "Required",
            EmailAddress = new Emailaddress { Name = user.GetName(), Address = user.GetEmail() }
        };
        invite.Start = new Start { DateTime = session.DateTime_Start };
        invite.End = new End { DateTime = session.DateTime_Start.AddMinutes(15) };
        invite.Subject = session.Name;
        invite.Body = new Body { ContentType = "HTML", Content = $"Some Content" };

        return JsonConvert.SerializeObject(eventInvite);

  } 

I am getting a Bad Request as response. Is there any alternative to build an Event? I want this code to be very thin as this is accessed in non UI based application

What is the best way to create Calendar Event?

The fix involves setting up the Timezone in the Start and End

   string timeZone="Singapore Standard Time";
   invite.Start = new Start { DateTime = session.DateTime_Start, TimeZone = timeZone };
   invite.End = new End { DateTime = session.DateTime_Start.AddMinutes(60), TimeZone = timeZone };
   var postBody = JsonConvert.SerializeObject(invite, Formatting.Indented);
