我两次收到相同的消息

本文介绍了我两次收到相同的消息的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

如果新用户开始对话，我使用此代码发送不同的消息:

I used this code to send a different message if a new user start conversation :

IConversationUpdateActivity update = message; var client = new ConnectorClient(new Uri(message.ServiceUrl), new MicrosoftAppCredentials()); if (update.MembersAdded != null && update.MembersAdded.Any()) { foreach (var newMember in update.MembersAdded) { if (newMember.Id != message.Recipient.Id) { var reply = message.CreateReply(); reply.Text = $"Welcome {newMember.Name}! You are a new member! If you want to see help menu , type : help"; client.Conversations.ReplyToActivityAsync(reply); } } }

我的问题是，当用户单击facebook时:开始使用，此消息出现两次.

My problem is that when a user click in facebook : Get started this message comes twice.

你能帮我吗?

推荐答案

Facebook将该对话本身包含在成员列表中:

Facebook includes the conversation itself in the list of members:

因此，您需要将if语句更改为此:

So you need to change the if statement to this:

if (newMember.Id != message.Recipient.Id && newMember.Id != message.Conversation.Id) { // send welcome message
