我可以将WPF TextBlock高度限制为两行吗？

I just received a requirement to display a length of text in a control. The control is of a particular width and will be up to 2 lines in height. If it renders longer than two lines it will just display "..." at the end of the string.

我刚收到要求在控件中显示一段文本的要求。控件具有特定的宽度,高度最多为2行。如果它渲染超过两行,它将只在字符串的末尾显示“...”。

Is this possible with any of the stock standard WPF controls?

这是否可以使用任何库存标准WPF控件?

Thanks, D.

Set the Height of the TextBlock to be high enough to fit two lines. Set the TextWrapping to Wrap and the TextTrimming to CharacterEllipsis or WordEllipsis.

将TextBlock的高度设置为足够高以适合两行。将TextWrapping设置为Wrap,将TextTrpping设置为CharacterEllipsis或WordEllipsis。

For the default Segoe UI 12Pt font, I find this does it

对于默认的Segoe UI 12Pt字体,我发现这样做

<TextBlock TextWrapping="Wrap" Height="40" TextTrimming="CharacterEllipsis" />

You could probably do some code behind to work out the height it should be be for a particular font if you want.

如果你愿意的话,你可以在后面编写一些代码来计算特定字体的高度。

That's not standard behavior that I've ever found, but again I've not looked for it.

这不是我所发现的标准行为,但我再也没有找到它。

One possibility is to use a monospace font in a TextArea control, and then if the string is greater than however many characters fit in the area, only display the right N characters with the ellipses

一种可能性是在TextArea控件中使用等宽字体,然后如果字符串大于该区域中适合的多个字符,则只显示带有省略号的正确N个字符
