Microsoft Graph OnlineMeeting 获取 JoinWebUrl

Question

I want to use the Microsoft Graph API to create an OnlineMeeting and wants to get the JoinWebUrl out off the response. How can I do that?

I already have this:

var onlineMeeting = new OnlineMeeting
        {
            StartDateTime = DateTimeOffset.Parse("2021-12-08T21:30:34.2444915+00:00"),
            EndDateTime = DateTimeOffset.Parse("2021-12-08T22:00:34.2464912+00:00"),
            Subject = "User Token Meeting"
        };

        var meeting = await graphClient.Users["mailaccount"].OnlineMeetings
             .Request()
             .AddAsync(onlineMeeting);

Answer 1

You need an organizer for an online meeting. The organizer will provide the location to store information of the meeting inside Teams.

Or at least this is how we are doing it...

var request = new OnlineMeeting
{
    StartDateTime = DateTime.UtcNow,
    EndDateTime = DateTime.UtcNow.AddHours(1),
    Subject = "User Token Meeting",
    Participants = new MeetingParticipants
    {
        Organizer = new MeetingParticipantInfo
        {
            Identity = new IdentitySet
            {
                User = new Identity
                {
                    Id = "<objectId of a real user>"
                }
            }
        }
    },
    AccessLevel = AccessLevel.Everyone,
};

var onlineMeeting = await (await ClientAsync())
    .Communications.OnlineMeetings.Request().AddAsync(request);

I would like something like this:

            var onlineMeeting = new OnlineMeeting
        {
            StartDateTime = DateTimeOffset.Parse("2021-12-08T21:30:34.2444915+00:00"),
            EndDateTime = DateTimeOffset.Parse("2021-12-08T22:00:34.2464912+00:00"),
            Subject = "User Token Meeting"
        };

        var meeting = graphClient.Users["mailaccount"].OnlineMeetings
             .Request()
             .AddAsync(onlineMeeting);

        LabelURL.Text = meeting.Result.JoinWebUrl;
