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
在Iconfont网站上找到图标后，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：
