运行操作时C＃WPF动画结束(Run action when c# wpf animation en

我在学习WPF，并在同一时间开发它的应用程序。 我有一个很难搞清楚当DoubleAnimation是（或其他种类）做我如何运行的东西。 例如：

DoubleAnimation myanim = new DoubleAnimation();
myanim.From = 10;
myanim.To = 100;
myanim.Duration = new Duration(TimeSpan.FromSeconds(3));
myview.BeginAnimation(Button.OpacityPropert, myanim);

//Code to do something when animation ends

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Windows.Media.Animation;

namespace app
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        DoubleAnimation widthbutton = new DoubleAnimation();
        widthbutton.From = 55;
        widthbutton.To = 100;
        widthbutton.Duration = new Duration(TimeSpan.FromSeconds(1.5));
        button1.BeginAnimation(Button.HeightProperty, widthbutton);

        DoubleAnimation widthbutton1 = new DoubleAnimation();
        widthbutton1.From = 155;
        widthbutton1.To = 200;
        widthbutton1.Duration = new Duration(TimeSpan.FromSeconds(1.5));
        button1.BeginAnimation(Button.WidthProperty, widthbutton1);

        widthbutton.Completed += new EventHandler(myanim_Completed);
    }
    private void myanim_Completed(object sender, EventArgs e)
    {
        //your completed action here
        MessageBox.Show("Animation done!");
    }
}
}

这是怎么accomplishable？ 我看了一下这个相当多的其他职位，但他们都用它XAML，但我想用C＃编写代码的时候做解释。 谢谢！

Answer 1:

您可以将一个事件处理程序DoubleAnimation是的完成事件。

myanim.Completed += new EventHandler(myanim_Completed);

private void myanim_Completed(object sender, EventArgs e)
{
    //your completed action here
}

或者，如果你喜欢它内联，你可以做

 myanim.Completed += (s,e) => 
     {
        //your completed action here
     };

记得开始动画否则它不会开火之前附加处理程序。
