Microsoft.图形服务异常："代码：错误请求消息：此通道不支持的操作

Question

我使用这个文档- https://learn.microsoft.com/ru-ru/graph/api/channel-post-members?view=graph-rest-1.0&tabs=csharp%2Chttp.

我得到这个消息，当我想添加成员在通道输入图像这里

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

我在这里创建了通道

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);  

怎么了?

Answer 1

我发现我必须使用

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

Answer 2

将conversationMember添加到通道中，此操作仅允许用于membershipType的通道。私人这解释了错误。
