如何得到一个字符串宽度 [英] How to get a string width

问题描述

我需要建立一个类库，一个字符串并将此字符串特定字体功能则得到字符串的宽度

I need to build a function in a class library that take a string and a specific font for this string then get the width of the string

所以，我怎么会得到字符串边界宽度？

So how could I get the string boundary width ?

推荐答案

另一种方式做，这是一个 TextRenderer ，并调用的及其的 MeasureString 方法，传递字符串和字体类型

Another way to do this is with a TextRenderer, and call its MeasureString method, passing the string and the font type.

MSDN示例：

private void MeasureText1(PaintEventArgs e)
{
    String text1 = "Measure this text";
    Font arialBold = new Font("Arial", 12.0F);
    Size textSize = TextRenderer.MeasureText(text1, arialBold);
    TextRenderer.DrawText(e.Graphics, text1, arialBold, 
        new Rectangle(new Point(10, 10), textSize), Color.Red);  
}

注意：这仅仅是一个替代的解决方案的（同样有效）已经发表@Neil巴恩韦尔
（如果你已经在你的项目中，这可能是更方便的System.Windows.Forms的引用）之一。

NOTE: This is just an alternate solution to the (equally valid) one already posted by @Neil Barnwell (in case you already have a reference to System.Windows.Forms in your project, this might be more convenient).
