为什么TextRenderer.MeasureText无法正常工作？ [英] Why doesn't TextRenderer.MeasureText work properly?

问题描述

在给定可用画布一定宽度的情况下，我想测量文本的高度。我传递的文字非常长，我知道会自动换行。为此，我将其称为：

I want to measure the height of the text given a certain width of available canvas. The text that I pass in is really long and I know will wrap. To that end, I call the following:

using System.Windows.Forms;
...
string text = "Really really long text that is sure to wrap...";
Font font = new Font("Arial", 14);
Size canvas = new Size(1100, 850);
Size size = TextRenderer.MeasureText(text, font, canvas);

无论我为画布传递什么，它总是为 size返回14高度。

No matter what I pass in for canvas, it always returns 14 for size.Height.

我错过了一些简单的东西吗？

Am I missing something simple?

推荐答案

请使用 TextFormatFlags 测量参数，如下所示：

Please, use the TextFormatFlags measure parameter as shown below:

Size size = TextRenderer.MeasureText(text, font, canvas, TextFormatFlags.WordBreak);
