WPF 实现测量显示文本长度
以工具类的方式实现：
using System;
using System.Windows;
using System.Windows.Media;
using System.Globalization;
using System.Windows.Controls;
namespace Tool
{
static class GetTextDisplayWidthHelper
{
public static Double GetTextDisplayWidth(Label label)
{
return GetTextDisplayWidth(label.Content.ToString(), label.FontFamily, label.FontStyle, label.FontWeight, label.FontStretch, label.FontSize);
}
public static Double GetTextDisplayWidth(string str, FontFamily fontFamily, FontStyle fontStyle, FontWeight fontWeight, FontStretch fontStretch,double FontSize)
{
var formattedText = new FormattedText(
str,
CultureInfo.CurrentUICulture,
FlowDirection.LeftToRight,
new Typeface(fontFamily, fontStyle, fontWeight, fontStretch),
FontSize,
Brushes.Black
);
Size size = new Size(formattedText.Width, formattedText.Height);
return size.Width;
}
}
}
