I use this documentation - https://docs.microsoft.com/ru-ru/graph/api/channel-post-members?view=graph-rest-1.0&tabs=csharp,http.

I get this message, when I want to add member in channel enter image here

 var conversationMember = new AadUserConversationMember
            {
                Roles = new List<String>()
                {

                },
                AdditionalData = new Dictionary<string, object>()
                {
                    {userBind, $"https://graph.microsoft.com/v1.0/users('{userId}')"}
                }
            };

            await graphClient.Teams[$"{teamId}"].Channels[$"{channelId}"].Members
                .Request()
                .AddAsync(conversationMember);// Here I get error

I created channel here

            var team = new Team
            {
                DisplayName = department.Name,
                Channels = new TeamChannelsCollectionPage()
                {

                },
                Members = new TeamMembersCollectionPage()
                {
                    new AadUserConversationMember
                    {
                        Roles = new List<String>()
                        {
                            "owner"
                        },
                        AdditionalData = new Dictionary<string, object>()
                        {
                            { userBind, $"https://graph.microsoft.com/v1.0/users('{ownerId}')" }
                        },
                    }
                },

                AdditionalData = new Dictionary<string, object>()
                {
                    { templateBind, urlTeamsApiStandard },
                }
            };

            foreach (var bitrixChannel in department.Channels)
            {
                var channel = new Channel
                {
                    DisplayName = bitrixChannel.Name,
                    MembershipType = ChannelMemberShipType.Private // Here I choose private, which doesnt work
                };

                team.Channels.Add(channel);
            }

            await graphClient.Teams
                     .Request()
                     .AddAsync(team);  

What is wrong?

UPD: I found that my channels in ms teams creates in not private mode, even if I choosed private. But I don't understand why

CodePudding user response：

Adding conversationMember to the channel, this operation is only allowed for channels with a membershipType value private which explains the error.

If this is useful, consider upvoting.

Thanks.

CodePudding user response：

I found that I have to use

await graphClient.Teams[teamId].Channels
                 .Request()
                     .AddAsync(channel);
