如何获得WinRT应用程序中字体的大小（以像素为单位）？ [英] How to get the size (in pixels) of a font in WinRT app?

问题描述

在.NET 4.5中我们有一个字体类，可以给你像素的高度，但是在WinRT中怎么样？

是否有任何API我可以用它来获取它使用的像素？因为在Windows应用商店的.NET API中不存在FormattedText类应用程序我的解决方法是使用TextBlock：

  TextBlock dummyTextBlock = new TextBlock（）; 
 dummyTextBlock.FontFamily = new FontFamily（Tahoma）; 
 dummyTextBlock.FontSize = 18; 
 dummyTextBlock.FontStyle = FontStyle.Normal; 
 dummyTextBlock.FontWeight = FontWeights.Bold; 
 dummyTextBlock.Text =X; 
 dummyTextBlock.Measure（new Size（0,0））; 
 dummyTextBlock.Arrange（new Rect（0,0,0,0））; 
 double width = dummyTextBlock.ActualWidth; 
 double height = dummyTextBlock.ActualHeight; 
  

这会显示文本的高度（宽度）。 >

As titled, in .NET 4.5 we have a font class which can give you the Height in pixes, but how about in WinRT?

Is there any API that I can use to get the pixels it uses?

解决方案

Since not even the FormattedText class exists in the .NET API for Windows Store Apps my workaround is to use a TextBlock:

TextBlock dummyTextBlock = new TextBlock();
dummyTextBlock.FontFamily = new FontFamily("Tahoma");
dummyTextBlock.FontSize = 18;
dummyTextBlock.FontStyle = FontStyle.Normal;
dummyTextBlock.FontWeight = FontWeights.Bold;
dummyTextBlock.Text = "X";
dummyTextBlock.Measure(new Size(0,0));
dummyTextBlock.Arrange(new Rect(0,0,0,0));
double width = dummyTextBlock.ActualWidth;
double height = dummyTextBlock.ActualHeight;

That gives you the height (and width) of a text how it would be displayed.
