如何在WeBbrowser中显示我发送的消息？ [英] how to show my sent message in WeBbrowser?

问题描述

我有一个棘手的问题，

当我编程时，我看一些参考，它显示了如何显示我和参与者之间的消息，我可以很容易地找到如何显示我收到的消息：这里是关键程序的一部分

when i am programming ,i take a look at some reference,it shows how to display the messages between me and the participant,i can easily find out how to display the message i receive:here are part of key program

_conversation.add（receivemessage）;

 对象[] actionObjectArray = {发件人，_ConversationHistory};

  this.Dispatcher.Invoke（FormActor，新的对象[] {FormActions.SetListContents，History_WebBrowser，actionObjectArray}）; // prgram从奥斯丁

 壳体FormActions.SetListContents：   //清晰并更新对话历史web浏览器中的内容

 case FormActions.SetListContents:   //clear and update the contents of the conversation history WebBrowser

             &NBSP ;          // ********* ***

                   &NBSP ;    //铸造动作数据到对象的阵列

                         // ********* ***

                   &NBSP ;   对象[] actionDataArray =（对象[]）actionData;

                        //***************************************************
                        //cast action data to array of object.
                        //***************************************************
                        object[] actionDataArray = (object[])actionData;

             &NBSP ;          // ********* ***

                   &NBSP ;    //从对话动态数据阵列中取出对话历史记录的一个列表

                         // ********* ***

                   &NBSP ;   的ArrayList historyArray =（ArrayList的）actionDataArray [1];

                        //***************************************************
                        //Get the arraylist of conversation history out of the action data array
                        //***************************************************
                        ArrayList historyArray = (ArrayList)actionDataArray[1];

                         // ********* ***

                   &NBSP ;    //从动作数据的第一个元素中获取消息发送者的姓名


                         // ********* ***

                   &NBSP ;    string sender =（string）actionDataArray [0];

                        //***************************************************
                        //Get the name of the message sender out of first element of action data
                        //***************************************************
                        string sender = (string)actionDataArray[0];

                         // ********* ***

                   &NBSP ;    //从对话历史数组中获取最新消息文本


              ;           // ********* ***

                   &NBSP ;   串receivedMessage = historyArray [historyArray.Count - 1]的ToString（）;

                        //***************************************************
                        //Get the newest message text out of the conversation history array
                        //***************************************************
                        string receivedMessage = historyArray[historyArray.Count - 1].ToString();

           &NBSP ;            // ********* ***

                   &NBSP ;    //将操作对象转换为要更新的控件类型


                         // ********* ***

                   &NBSP ;    web浏览器webBrowserToUpdate =（web浏览器）actionObject;

                        //***************************************************
                        //Cast the object of action to the control type to be updated
                        //***************************************************
                        WebBrowser webBrowserToUpdate = (WebBrowser)actionObject;

               &NBSP ;        // ********* ***

                   &NBSP ;    //拼接以前的历史，以新的消息


                         // ********* ***

                        //***************************************************
                        //Concatenate the previous history to the new message
                        //***************************************************

                         _ConversationHistoryHtml.Insert（0，发件人+ receivedMessage）;

               &NBSP ;        webBrowserToUpdate.NavigateToString（_ConversationHistoryHtml.ToString（））;

                        _ConversationHistoryHtml.Insert(0, sender + receivedMessage);
                        webBrowserToUpdate.NavigateToString(_ConversationHistoryHtml.ToString());

                         // ********* ***

                   &NBSP ;    //更新历史数组以用
替换最新的消息                        //消息发送者的名字+最新消息文本

                         // ********* ***

                   &NBSP ;    string recMessage = sender +"：" + receivedMessage;

                   &NBSP ;    historyArray.RemoveAt（historyArray.Count - 1）;

               &NBSP ;        historyArray.Add（recMessage）;

                        //***************************************************
                        //Update the history array to replace the newest message with
                        //the message sender name + the newest message text.
                        //***************************************************
                        string recMessage = sender + ": " + receivedMessage;
                        historyArray.RemoveAt(historyArray.Count - 1);
                        historyArray.Add(recMessage);

它真的有效。

但如何让它显示我收到的消息？

but how to let it show my sent message?

推荐答案

处理（（InstantMessageModality）Conversation.Modalities [ModalityType.InstantMessage]）。InstantMessageReceived事件。 当您发送消息以及从远程用户收到消息时，会引发此事件。 您收到了您在此活动中发送的消息
。

Handle the ((InstantMessageModality)Conversation.Modalities[ModalityType.InstantMessage]).InstantMessageReceived event.  This event is raised when you send a message as well as when a message is received from a remote user.  You get the message text that you sent in this event.
