【问题描述】：

我正在寻找一些关于动画窗口调整打开窗口大小的帮助！似乎无法弄清楚这一点！

我只是在使用自动取款机。

this.Width = 500;

任何帮助都会很棒！谢谢。

【解决方案1】：

我自己已经回答了这个问题。这是一些示例代码。

    static System.Windows.Forms.Timer _Timer = new System.Windows.Forms.Timer(); 
    int _Stop = 0;

    private void This_Loaded(object sender, RoutedEventArgs e)
    {
        _Timer.Tick += new EventHandler(timer_Tick);
        _Timer.Interval = (20); 

        resize(500,500)
    }

    private void timer_Tick(Object myObject, EventArgs myEventArgs)
    {
        if (_Stop == 0)
        {
            _RatioHeight    = ((this.Height -   _Height)    / 12)* -1;
            _RatioWidth     = ((this.Width -    _Width)     / 12)* -1;
        }
        _Stop++;

        this.Height += _RatioHeight;
        this.Width  += _RatioWidth;

        if (_Stop == 12)
        {
            _Timer.Stop();
            _Timer.Enabled = false;
            _Timer.Dispose();

            _Stop = 0;

            this.Height = _Height;
            this.Width  = _Width;
        }
    }

    public void resize(double _PassedHeight, double _PassedWidth)
    {
        _Height = _PassedHeight;
        _Width  = _PassedWidth;

        _Timer.Enabled = true;
        _Timer.Start();
    }

以 12 个“滴答声”非常快速地调整窗口大小，可以在 _Timer.Interval 中放慢速度。在 12 个刻度后将其打磨掉，最终调整为精确大小。

希望这对某些人有所帮助。

你可以使用窗口动画，这里是 xaml

<Window x:Class="dlgControls" Name="dlgControls"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="" Height="300" Width="300">

    <Window.Resources>
        <Storyboard x:Key="showWin">
            <DoubleAnimation Storyboard.TargetName="dlgControls" Storyboard.TargetProperty="Height" Duration="0:0:.5" To="300" BeginTime="0:0:1"/>
        </Storyboard>

        <Storyboard x:Key="hideWin">
            <DoubleAnimation Storyboard.TargetName="dlgControls" Storyboard.TargetProperty="Height" Duration="0:0:.5" To="150" BeginTime="0:0:1"/>
        </Storyboard>
    </Window.Resources>
    <Grid RenderTransformOrigin="0.5,0.5">
        <Button Name="btnOpen" Content="Open" HorizontalAlignment="Left" Margin="184,98,0,0" VerticalAlignment="Top" Width="75"/>
        <Button Name="btnClose" Content="Close" HorizontalAlignment="Left" Margin="184,222,0,0" VerticalAlignment="Top" Width="75"/>
    </Grid>

</Window>

动画使用这样的代码

Imports System.Windows.Media.Animation

Public Class dlgControls
    Dim showWin As Storyboard
    Dim hideWin As Storyboard

    Private Sub btnOpen_Click(sender As Object, e As Windows.RoutedEventArgs) Handles btnOpen.Click
        BeginStoryboard(showWin)
    End Sub

    Private Sub dlgControls_Loaded(sender As Object, e As Windows.RoutedEventArgs) Handles Me.Loaded
        showWin = Me.Resources("showWin")
        hideWin = Me.Resources("hideWin")
    End Sub

    Private Sub btnClose_Click(sender As Object, e As Windows.RoutedEventArgs) Handles btnClose.Click
        BeginStoryboard(hideWin)
    End Sub
End Class

不敢相信这没有更多的选票。非常优雅，正好解决了我的问题

【解决方案3】：

System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += dispatcherTimer_Tick;
dispatcherTimer.Interval = new TimeSpan(0,0,0,0,10); // Control animation speed / how often the tick will be called.
dispatcherTimer.Start();


private void dispatcherTimer_Tick(object sender, EventArgs e)
{
     if ( this.Width < 500 )
     {
           this.Width += 10;
     } 
     else 
     {
           DispatcherTimer timer = (DispatcherTimer)sender;
           timer.Stop();
     }
}
