问题
I have a WPF Label control which I'm trying to change the appearance of using a System.Drawing.Font object supplied by some legacy code. I have been able to set most of the properties, but am struggling with Strikeout and Underline.
So far I have:
System.Drawing.Font font = FontFromLegacyCode();
System.Windows.Controls.Label label = new System.Windows.Controls.Label();
label.FontFamily = new System.Windows.Media.FontFamily( font.Name );
label.FontWeight = font.Bold ? System.Windows.FontWeights.Bold : System.Windows.FontWeights.Regular;
label.FontStyle = font.Italic ? System.Windows.FontStyles.Italic : System.Windows.FontStyles.Normal;
label.FontSize = font.Size;
How do you set the font strikeout or underline properties? Is there a better control to use?
回答1:
I would change it to a TextBlock control. The TextBlock control has the TextDecorations property you can use.
<TextBlock Name="textBlock" TextDecorations="Underline, Strikethrough" />
Or you can stick a TextBlock inside a Label if you really like (although I'd just use the TextBlock by itself).
<Label Name="label">
<TextBlock Name="textBlock" TextDecorations="Underline, Strikethrough" />
</Label>
Have a look at the TextDecorations class.
I find that TextBlocks are more suitable than Labels in most situations. Here's a blog post about the differences. The chief difference being that a Label is a Control whereas a TextBlock is just a FrameworkElement. Also a Label supports access keys.

Looking at the code you already have, there might be a problem with it. On the MSDN on Windows Form and WPF Property mapping they make the comment:
Font size in WPF is expressed as one ninety-sixth of an inch, and in Windows Forms as one seventy-second of an inch. The corresponding conversion is:
Windows Forms font size = WPF font size * 72.0 / 96.0.
