如何在UWP Apps中测量文本大小？ [英] How can I measure the Text Size in UWP Apps?

问题描述

在WPF中，可以使用 FormattedText

In WPF, this was possible using FormattedText, like this:

private Size MeasureString(string candidate)
{
    var formattedText = new FormattedText(
        candidate,
        CultureInfo.CurrentUICulture,
        FlowDirection.LeftToRight,
        new Typeface(this.textBlock.FontFamily, this.textBlock.FontStyle, this.textBlock.FontWeight, this.textBlock.FontStretch),
        this.textBlock.FontSize,
        Brushes.Black);

    return new Size(formattedText.Width, formattedText.Height);
}

但是在UWP中，该类不再存在。那么如何在通用Windows平台中计算文本尺寸呢？

But in UWP this class does not exist any more. So how is it possible to calculate text dimensions in universal windows platform?

推荐答案

在UWP中，您创建了 TextBlock ，设置其属性（例如 Text ， FontSize ），然后调用其 测量 方法并传递无限大小。

In UWP, you create a TextBlock, set its properties (like Text, FontSize), and then call its Measure method and pass in infinite size.

var tb = new TextBlock { Text = "Text", FontSize = 10 };
tb.Measure(new Size(Double.PositiveInfinity, Double.PositiveInfinity));

之后，其 DesiredSize 属性包含TextBlock将具有的大小。

After that its DesiredSize property contains the size the TextBlock will have.
