BotFramework 1:1 对话引发错误 "activityid can not be null"

Question

尝试使用以下代码创建 1:1 对话时，我收到错误提示 "activityid cannot be null" 谁能帮我指出问题所在？

 var newRecipient = new ChannelAccount();
                            newRecipient.Name = user.Mentioned.Name;
                            newRecipient.Id = user.Mentioned.Id;

                            var ConversationId = await connector.Conversations.CreateDirectConversationAsync(activity.Recipient, newRecipient);
                            IMessageActivity message = Activity.CreateMessageActivity();
                            message.From = activity.Recipient;
                            message.Recipient = newRecipient;
                            message.Conversation = new ConversationAccount(id: ConversationId.Id);
                            message.Text = $"Congratulations {user.Mentioned.Name}!, you have got a :tangerine: from {activity.From.Name}";
                            message.Locale = "en-Us";
                            message.Id = Guid.NewGuid().ToString(); 
                            var reply = await connector.Conversations.ReplyToActivityAsync((Activity)message);

Answer 1

您正在使用：

ReplyToActivityAsync

但不回复现有对话，而是创建一个新对话。您应该改用以下内容：

SendToConversationAsync
