推荐答案

取决于。您使用的是ASP.NET还是Windows Forms或WPF？您是使用固定宽度还是比例字体？

Depends. Are you using ASP.NET or Windows Forms or WPF? Are you using a fixed-width or proportional font?

如果您使用的是Windows窗体，则需要调用 MeasureString（），以了解您想要的文本宽度。

If you're using Windows Forms, you will want to call MeasureString() in order to find out how wide you want the text to be.

如果您使用ASP.NET，您可以执行类似MeasureString（），但您不知道在浏览器上呈现什么字体，因此你不能把它放在脚本中。

If you're using ASP.NET, you can do something like MeasureString(), but you don't know exactly what font is being rendered on the browser, so you can't just put that in your script.
