如何在WPF中计算字体高度？

    FontFamily fontFamily = new FontFamily("Segoe UI");
    double fontDpiSize = 16;

    double fontHeight = Math.Ceiling(fontDpiSize * fontFamily.LineSpacing);

   22.0

System.Windows.Media.FormattedText

FormattedText ft = new FormattedText("Quick Brown Fox Jumps Over A Lazy Dog.",
                                     CultureInfo.CurrentCulture,
                                     CultureInfo.CurrentCulture.TextInfo.IsRightToLeft ? FlowDirection.RightToLeft : FlowDirection.LeftToRight,
                                     new Typeface("Verdana"),
                                     9,
                                     new SolidColorBrush(Colors.White)
Double maxHeight = ft.MaxTextHeight;
