毕业设计网站开发的目的和意义制作自己的网页

实现冒泡排序代码就不过多讲解，主要是实现动画效果思路，本demo使用MVVM模式编写，读者可自行参考部分核心代码，即可实现如视频所示效果。
对于新手了解算法相关知识应该有些许帮助，至于其它类型排序，也可按该思路自行修改实现。
直接上代码，页面布局.xaml代码如下：

<UserControl x:Class="Wpf_MetroListBox.Views.Test.CanvasLabelMove"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:Wpf_MetroListBox.Views.Test"mc:Ignorable="d" d:DesignHeight="450" d:DesignWidth="800"><Grid><Grid.RowDefinitions><RowDefinition Height="380"></RowDefinition><RowDefinition Height="*"></RowDefinition></Grid.RowDefinitions><Canvas x:Name="canvas" Grid.Row="0" Background="White"></Canvas><Grid Grid.Row="1"><Grid.ColumnDefinitions><ColumnDefinition></ColumnDefinition><ColumnDefinition></ColumnDefinition></Grid.ColumnDefinitions><Button Content="创建序列" HorizontalAlignment="Center"  Grid.Column="0" Width="70" Height="35" Command="{Binding CommitCommand}" Style="{DynamicResource btn-info-m}"></Button><Button  Content="执行排序" HorizontalAlignment="Center"  Grid.Column="1" Width="70" Height="35" Command="{Binding QueryCommand}" Style="{DynamicResource btn-info-m}"></Button></Grid></Grid></UserControl>

逻辑代码实现如下：

public partial class CanvasLabelMove : UserControl{CanvasLabelMoveViewModel vm;private Random random = new Random();private List<Label> labels = new List<Label>();private int[] array;private int delay = 1000; // 动画延迟时间（毫秒）public CanvasLabelMove(){InitializeComponent();vm = new CanvasLabelMoveViewModel();this.DataContext = vm;this.Publish(EventNames.MainWindowLoadControlEvent, "排序可视化");this.Subscriber<string>(EventNames.DataGridFocusChangedEvent, async contentStr =>{  if (contentStr.Equals("1")){InitializeArrayAndLabels();}else if (contentStr.Equals("2")){StartBubbleSortAnimation();}});}private void InitializeArrayAndLabels(){int size = 18; // 数组大小 控制标签个数array = new int[size];labels.Clear();canvas.Children.Clear();HashSet<int> randomNumbers = new HashSet<int>();Random random = new Random();//生成不重复随机数while (randomNumbers.Count < size){int nextNumber = random.Next(22, 200);randomNumbers.Add(nextNumber);}int j = 0;foreach (int number in randomNumbers){array[j] = number;j++;}for (int i = 0; i < size; i++){Label label = new Label{Content = array[i].ToString(),FontSize = 12,Width = 35,Height = array[i],Margin = new Thickness(50, 0, 0, 0),Foreground = Brushes.Black,Background = Brushes.BlanchedAlmond,VerticalContentAlignment = VerticalAlignment.Center,HorizontalContentAlignment = HorizontalAlignment.Center};             Canvas.SetLeft(label, i * 50); // 设置Label的X坐标Canvas.SetBottom(label, (canvas.ActualHeight / 2) - 100); // 设置Label的Y坐标在中间canvas.Children.Add(label);labels.Add(label);}}private async void StartBubbleSortAnimation(){for (int j = 0; j <= array.Length - 1; j++){for (int i = 0; i <= array.Length - 2; i++){if (array[i] > array[i + 1]){Swap(i, i + 1);// 更新Label位置AnimateSwap(i, i + 1);await Task.Delay(delay);}}}}private void Swap(int i, int j){int temp = array[i];array[i] = array[j];array[j] = temp;}private async void AnimateSwap(int i, int j){// 临时存储Label的位置double label1X = Canvas.GetLeft(labels[i]);double label2X = Canvas.GetLeft(labels[j]);await Task.Delay(delay / 10); // 控制动画速度var animation1 = new DoubleAnimation(label2X, TimeSpan.FromSeconds(0.5));var animation2 = new DoubleAnimation(label1X, TimeSpan.FromSeconds(0.5));labels[i].BeginAnimation(Canvas.LeftProperty, animation1);labels[j].BeginAnimation(Canvas.LeftProperty, animation2);// 最终位置//Canvas.SetLeft(labels[i], label2X);//Canvas.SetLeft(labels[j], label1X);Label tempLabel = labels[i];labels[i] = labels[j];labels[j] = tempLabel;}}public class CanvasLabelMoveViewModel : BaseValidViewModel{public CanvasLabelMoveViewModel(){}protected override void ExecuteCommitCommand(){this.Publish(EventNames.DataGridFocusChangedEvent, "1");}protected override void ExecuteQueryCommand(){this.Publish(EventNames.DataGridFocusChangedEvent, "2");}}
