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

问题描述

在 WPF 中，这可以使用 FormattedText 实现，如下所示:

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 中这个类已经不存在了.那么如何在通用windows平台下计算文本尺寸呢?

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，您创建一个 TextBlock，设置其属性(如 Text、FontSize)，然后调用其测量方法并传入无限大小.

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));

之后是 DesiredSize 属性包含 TextBlock 的大小.

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