当输出到标签时是否有保存格式的方法?

I have some user input that I am outputting to a label.

我有一些用户输入，我输出到一个标签。

I have used HTML.Encode in order to show the input in the way the user entered it (ignoring as a html tag).

我已经使用HTML。对输入进行编码，以显示用户输入的方式(忽略为html标记)。

However, I have noticed that the user input like New Line are not using in the label. It's simply displayed as white space.

但是，我注意到用户输入如New Line在标签中没有使用。它只是显示为空白。

I've done this

我做了这个

                msg.Text = msg.Text.Replace(Environment.NewLine, "<br />");

which seems to now be displaying the right input.

它现在似乎显示了正确的输入。

Is that the best way to do this? Or is there like a common method that can convert newLines, tabs, etc. all of the invisible formatting things into HTML tags?

这是最好的方法吗?或者有没有一种常见的方法可以将换行符、制表符等所有不可见的格式转换成HTML标签?

I don't know of any other way. What I usually do (in case you have a single "\n" or a "\r\n" combo) is replace all "\r\n" first, then any single "\n" last.

我不知道还有别的办法。我通常做的(如果你有一个“\n”或“\r\n”组合)是先替换所有“\r\n”，然后再替换任何一个“\n”。

lbl.Text = lbl.Text.Replace("\r\n", "<br />").Replace("\n", "<br />");

For tabs you can use 4 non-breaking spaces.:

对于制表符，你可以使用4个不间断空格。

lbl.Text = lbl.Text.Replace("\t", "&nbsp;&nbsp;&nbsp;&nbsp;")

To preserve any spacing (as html will aggregate multiple continuous spaces into a single space) use:

为了保持任何间隔(html将多个连续空间聚合为一个空间)，使用:

lbl.Text = lbl.Text.Replace("  ", "&nbsp;&nbsp;")//Replace every 2-space pair.

Remember to Encode your text first before adding in markup like <br /> that you intentionally want to render.

在添加
等有意呈现的标记之前，请记住先对文本进行编码。

You could also use a TextBox, set it's MultiLine property to "true" and Enabled to "false" if you want to display the information with the original carriage returns without resorting to inserting markup. I think the label is the best choice though.

您还可以使用一个文本框，将它的MultiLine属性设置为“true”，如果您希望使用原始的回车来显示信息，而不需要使用插入标记，则可以将其设置为“false”。我认为标签是最好的选择。

If possible, just use a Multiline Textbox instead of label.

如果可能的话，使用多行文本框而不是标签。
