blocks|key|221331|text|因为您还没有指定您正在使用的前端(GUI技术)，所以很难做出具体的推荐。在WPF中，您可以创建一个列表框，并为每一行聊天添加一个新的listboxitem到集合的末尾。这篇link提供了一些关于如何在winforms环境中实现相同结果的建议。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|221332|entityMap|0|LINK|mutability|MUTABLE|url|http://www.pcreview.co.uk/forums/implement-chat-window-via-winforms-t1324368.html^0|2E|4|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Because you haven't specified what front end (GUI technology) you're using it would be hard to make a specific recommendation. In WPF you could create a listbox and for each new line of chat add a new listboxitem to the end of the collection. This <a href="http://www.pcreview.co.uk/forums/implement-chat-window-via-winforms-t1324368.html" rel="nofollow">link</a> provides some suggestions as to how you may achieve the same result in a winforms environment.

If you use WinForms:

Use the <code>AppendText(myTxt)</code> method on the <code>TextBox</code> instead (.net 3.5+):

<pre><code> private void button1_Click(object sender, EventArgs e)
 {
 string sent = chatBox.Text;

 displayBox.AppendText(sent);
 displayBox.AppendText(Environment.NewLine);

 }
</code></pre>

Text in itself has typically a low memory footprint (you can say a lot within f.ex. 10kb which is "nothing"). The TextBox does not render all text that is in the buffer, only the visible part so you don't need to worry too much about lag. The slower operations are inserting text. Appending text is relatively fast.

If you need a more complex handling of the content you can use <code>StringBuilder</code> combined with the textbox. This will give you a very efficient way of handling text.

blocks|key|439649|text|我发现这种方法节省了大量的输入，并防止了大量的打字错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|439650|string+nl+=+"\r\n"；|439651|txtOutput.Text+=“第一行”%2B+nl+%2B“第二行”%2B+nl+%2B“第三行”；|439652|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I find this method saves a lot of typing, and prevents a lot of typos.

string nl = "\r\n";

txtOutput.Text = "First line" + nl + "Second line" + nl + "Third line";

C# - serialData is <code>ReceivedEventHandler</code> in <code>TextBox</code>.

<pre><code>SerialPort sData = sender as SerialPort;
string recvData = sData.ReadLine();

serialData.Invoke(new Action(() =&gt; serialData.Text = String.Concat(recvData)));
</code></pre>

Now Visual Studio drops my lines. TextBox, of course, had all the correct options on.

Serial:

<pre><code>Serial.print(rnd);
Serial.( '\n' ); //carriage return
</code></pre>

I'm doing a chat client, and currently I have a button that will display data to a multi-line textbox when clicked. Is this the only way to add data to the multi-line textbox? I feel this is extremely inefficient, because if the conversation gets really long the string will get really long as well.

<pre><code>private void button1_Click(object sender, EventArgs e)
 {
 string sent = chatBox.Text;
 displayBox.Text += sent + "\r\n";

 }
</code></pre>

Adding new line of data to TextBox

Visual Studio

我正在做一个聊天客户端，目前我有一个按钮，当点击时，它会将数据显示到多行文本框中。这是向多行文本框添加数据的唯一方法吗？我觉得这是非常低效的，因为如果对话变得很长，字符串也会变得很长。private void button1_Click(object sender, EventArgs e)        {     ...
