刚在路上看见了小学同学正在捡矿泉水瓶子，心里很不是滋味，想不到昔日的玩伴如今竟然成了竞争对手。 

 

前言 

      需要实现环（圆）形菜单。

 

欢迎转发、分享、点赞，谢谢大家~。

一、CircularMenuItemCustomControl.cs代码如下：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Windows;using System.Windows.Controls;using System.Windows.Media;using System.Windows.Shapes;namespace WpfCircularMenu{ [TemplatePart(Name = RotateTransformTemplateName, Type = typeof(RotateTransform))] public class CircularMenuItemCustomControl : Control {  private static readonly Type _typeofSelf = typeof(CircularMenuItemCustomControl);  private const string RotateTransformTemplateName = "PART_RotateTransform";  private RotateTransform _angleRotateTransform;  public double Angle  {   get { return (double)GetValue(AngleProperty); }   set { SetValue(AngleProperty, value); }  }  public static readonly DependencyProperty AngleProperty =   DependencyProperty.Register("Angle", typeof(double), typeof(CircularMenuItemCustomControl), new UIPropertyMetadata(OnAngleChanged));  private static void OnAngleChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)  {   CircularMenuItemCustomControl control = (CircularMenuItemCustomControl)d;   control.UpdateAngle();  }  void UpdateAngle()  {   if (_angleRotateTransform == null) return;   _angleRotateTransform.Angle = Angle;  }  public string MenuTxt  {   get { return (string)GetValue(MenuTxtProperty); }   set { SetValue(MenuTxtProperty, value); }  }  public static readonly DependencyProperty MenuTxtProperty =   DependencyProperty.Register("MenuTxt", typeof(string), typeof(CircularMenuItemCustomControl), new PropertyMetadata(string.Empty));  public Brush BackgroundColor  {   get { return (Brush)GetValue(BackgroundColorProperty); }   set { SetValue(BackgroundColorProperty, value); }  }  public static readonly DependencyProperty BackgroundColorProperty =   DependencyProperty.Register("BackgroundColor", typeof(Brush), typeof(CircularMenuItemCustomControl), new PropertyMetadata(null));  public ImageSource IconImage  {   get { return (ImageSource)GetValue(IconImageProperty); }   set { SetValue(IconImageProperty, value); }  }  public static readonly DependencyProperty IconImageProperty =    DependencyProperty.Register("IconImage", typeof(ImageSource), typeof(CircularMenuItemCustomControl), new PropertyMetadata(null));    static CircularMenuItemCustomControl()  {   DefaultStyleKeyProperty.OverrideMetadata(_typeofSelf, new FrameworkPropertyMetadata(_typeofSelf));  }  public override void OnApplyTemplate()  {   base.OnApplyTemplate();   _angleRotateTransform = GetTemplateChild(RotateTransformTemplateName) as RotateTransform;   UpdateAngle();  }   }}

二、CircularMenuItemCustomControlStyle.xaml 代码如下

<ResourceDictionary ""     =""     ="clr-namespace:WpfCircularMenu"> <Style TargetType="{x:Type local:CircularMenuItemCustomControl}">  <Setter Property="Template">   <Setter.Value>    <ControlTemplate TargetType="local:CircularMenuItemCustomControl">     <Grid VerticalAlignment="Center">      <Grid.RenderTransform>       <RotateTransform x:Name="PART_RotateTransform" Angle="{TemplateBinding Angle}" CenterX="200" CenterY="200"></RotateTransform>      </Grid.RenderTransform>      <Path x:Name="PART_Path" Data="M 200,200 0,200 A 200,200 0 0 1 58.6,58.6z"         Fill="{TemplateBinding BackgroundColor}" VerticalAlignment="Center"/>      <Image Source="{TemplateBinding IconImage}" RenderTransformOrigin="0.5,0.5"         Margin="60,70,0,0"         HorizontalAlignment="Left"         VerticalAlignment="Center"         Width="40" Height="40" >       <Image.RenderTransform>        <RotateTransform Angle="-70"/>       </Image.RenderTransform>      </Image>     </Grid>     <ControlTemplate.Triggers>      <Trigger Property="IsMouseOver" Value="true">       <Setter TargetName="PART_Path" Property="Fill" Value="#009AD8"/>       <Setter Property="Cursor" Value="Hand"/>      </Trigger>     </ControlTemplate.Triggers>    </ControlTemplate>   </Setter.Value>  </Setter></Style></ResourceDictionary>

三、MainWindow.xaml 代码如下

四、MainWindow.xaml.cs 代码如下

<Window x:Class="WpfCircularMenu.MainWindow"  =""  =""  =""  =""  ="clr-namespace:WpfCircularMenu"  mc:Ignorable="d"  Title="MainWindow" Height="850" Width="1200"  Background="Black"  SnapsToDevicePixels="True"   TextOptions.TextFormattingMode="Display"   UseLayoutRounding="True"> <Window.Resources>  <Storyboard x:Key="CheckedStoryboard">   <DoubleAnimation Storyboard.TargetName="PART_EllipseGeometry"        Storyboard.TargetProperty="RadiusX"        Duration="00:00:0.4" To="200"/>   <DoubleAnimation Storyboard.TargetName="PART_EllipseGeometry"        Storyboard.TargetProperty="RadiusY"        Duration="00:00:0.4" To="200"/>  </Storyboard>  <Storyboard x:Key="UncheckedStoryboard">   <DoubleAnimation Storyboard.TargetName="PART_EllipseGeometry"        Storyboard.TargetProperty="RadiusX"        Duration="00:00:0.3" To="0"/>   <DoubleAnimation Storyboard.TargetName="PART_EllipseGeometry"        Storyboard.TargetProperty="RadiusY"        Duration="00:00:0.3" To="0"/>  </Storyboard> </Window.Resources> <Viewbox>  <Grid Height="768" Width="1024">   <Canvas>    <ItemsControl ItemsSou......
