之前每次使用IconFont图标，都要去下载一个png图片，每次颜色什么的改了，都要重新下载，太苦逼了。

现在好了，终于找到如何方便快速地使用IconFont图标了。

是应该的演示如何从IconFont网站上找到Geometry

先看看效果吧：

如视频中所示，找到图标后，按F12,选中需要的图标，查看页面源码，复制Path中的数据即可。

下面封装一个IconFontButton.加上简单的动画，直接看代码吧：

创建IconFontButton类：

using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;namespace WxDemo
{public class IconFontButton:Button{public Geometry Geometry{get { return (Geometry)GetValue(GeometryProperty); }set { SetValue(GeometryProperty, value); }}public static readonly DependencyProperty GeometryProperty =DependencyProperty.Register("Geometry", typeof(Geometry), typeof(IconFontButton), new PropertyMetadata(default(Geometry)));public CornerRadius CornerRadius{get { return (CornerRadius)GetValue(CornerRadiusProperty); }set { SetValue(CornerRadiusProperty, value); }}public static readonly DependencyProperty CornerRadiusProperty =DependencyProperty.Register("CornerRadius", typeof(CornerRadius), typeof(IconFontButton), new PropertyMetadata(default(CornerRadius)));public double IconWidth{get { return (double)GetValue(IconWidthProperty); }set { SetValue(IconWidthProperty, value); }}public static readonly DependencyProperty IconWidthProperty =DependencyProperty.Register("IconWidth", typeof(double), typeof(IconFontButton), new PropertyMetadata(32.0));public double IconHeight{get { return (double)GetValue(IconHeightProperty); }set { SetValue(IconHeightProperty, value); }}public static readonly DependencyProperty IconHeightProperty =DependencyProperty.Register("IconHeight", typeof(double), typeof(IconFontButton), new PropertyMetadata(32.0));}
}

在App.xaml中添加IconFontButton的样式：

<Application x:Class="WxDemo.App"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:local="clr-namespace:WxDemo"StartupUri="IconFontButtonDemo.xaml"><Application.Resources><Style TargetType="local:IconFontButton"><Setter Property="CornerRadius" Value="0"/><Setter Property="Padding" Value="5"/><Setter Property="Background" Value="Transparent"/><Setter Property="Foreground" Value="Gray"/><Setter Property="BorderBrush" Value="Transparent"/><Setter Property="Template"><Setter.Value><ControlTemplate TargetType="local:IconFontButton"><Border CornerRadius="{TemplateBinding CornerRadius}" Background="{TemplateBinding Background}" BorderThickness="0"><Path x:Name="path" Data="{TemplateBinding Geometry}" Fill="{TemplateBinding Foreground}"Width="{TemplateBinding IconWidth}"Height="{TemplateBinding IconHeight}"SnapsToDevicePixels="True"Stretch="Uniform"RenderTransformOrigin="0.5,0.5"Margin="{TemplateBinding Padding}"><Path.RenderTransform><TransformGroup><ScaleTransform ScaleX="1" ScaleY="1" /></TransformGroup></Path.RenderTransform></Path></Border><ControlTemplate.Triggers><EventTrigger RoutedEvent="UIElement.MouseEnter"><BeginStoryboard ><Storyboard><DoubleAnimation Storyboard.TargetName="path" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)" To="1.2" Duration="0:0:0.1" AutoReverse="False" /><DoubleAnimation Storyboard.TargetName="path" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)" To="1.2" Duration="0:0:0.1" AutoReverse="False" /></Storyboard></BeginStoryboard></EventTrigger><EventTrigger RoutedEvent="UIElement.MouseLeave"><BeginStoryboard><Storyboard><DoubleAnimation Storyboard.TargetName="path" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)" To="1" Duration="0:0:0.1" AutoReverse="False" /><DoubleAnimation Storyboard.TargetName="path" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)" To="1" Duration="0:0:0.1" AutoReverse="False" /></Storyboard></BeginStoryboard></EventTrigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter>
</Style></Application.Resources>
</Application>

创建一个窗体测试我们封装的按钮：
