以编程方式测量 Silverlight 的文本字符串(以像素为单位)
在 WPF 中,System.Windows.Media 命名空间中有 FormattedText MSDN FormattedText 我可以像这样使用:
private static Size GetTextSize(string txt, string font, int size, bool isBold)
{
Typeface tf = new Typeface(new System.Windows.Media.FontFamily(font),
FontStyles.Normal,
(isBold) ? FontWeights.Bold : FontWeights.Normal,
FontStretches.Normal);
FormattedText ft = new FormattedText(txt, new CultureInfo("en-us"), System.Windows.FlowDirection.LeftToRight, tf, (double)size, System.Windows.Media.Brushes.Black, null, TextFormattingMode.Display);
return new Size { Width = ft.WidthIncludingTrailingWhitespace, Height = ft.Height };
}
除了调用服务器之外,Silverlight 中是否有一个好的方法来获取以像素为单位的宽度(目前高度并不重要)?
In WPF there is the FormattedText in the System.Windows.Media namespace MSDN FormattedText that I can use like so:
private static Size GetTextSize(string txt, string font, int size, bool isBold)
{
Typeface tf = new Typeface(new System.Windows.Media.FontFamily(font),
FontStyles.Normal,
(isBold) ? FontWeights.Bold : FontWeights.Normal,
FontStretches.Normal);
FormattedText ft = new FormattedText(txt, new CultureInfo("en-us"), System.Windows.FlowDirection.LeftToRight, tf, (double)size, System.Windows.Media.Brushes.Black, null, TextFormattingMode.Display);
return new Size { Width = ft.WidthIncludingTrailingWhitespace, Height = ft.Height };
}
Is there a good approach in Silverlight to getting the width in pixels (at the moment height isn't important) besides making a call to the server?

我见过的一种方法可能不适用于您的特定实例,即将文本放入无样式的 TextBlock 中,然后获取该控件的宽度,如下所示:
毫无疑问,这是一种 hack。
An approach that I've seen used, that may not work in your particular instance, is to throw the text into an unstyled TextBlock, and then get the width of that control, like so:
It's a hack, no doubt.
