HOW TO：尋找腳本
更新：2007 年 11 月
下列範例示範如何使用 Storyboard 的 Seek 方法，跳到腳本動畫中的任何位置。
範例
以下是此範例的 XAML 標記。
<Page xmlns="https://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="https://schemas.microsoft.com/winfx/2006/xaml"
x:Class="SDKSample.SeekStoryboardExample">
<StackPanel Margin="20" >
<Rectangle Name="myRectangle"
Width="10" Height="20" Fill="#AA3333FF" HorizontalAlignment="Left" >
<Rectangle.Triggers>
<EventTrigger RoutedEvent="Rectangle.Loaded">
<BeginStoryboard Name="myBeginStoryboard">
<Storyboard Name="myStoryboard" Duration="0:0:4">
<DoubleAnimation
Storyboard.TargetName="myRectangle"
Storyboard.TargetProperty="Width"
Duration="0:0:4" From="10" To="500"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Rectangle.Triggers>
</Rectangle>
<!-- Use this slider to seek to different points of the Storyboard Duration
(in milliseconds). -->
<Slider Name="SeekSlider" ValueChanged="OnSliderValueChanged" Height="Auto"
Width="500" Minimum="0" Maximum="4000" HorizontalAlignment="Left" />
</StackPanel>
</Page>
以下是搭配上述 XAML 程式碼一起使用的程式碼。
using System;
using System.Media;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media.Animation;
namespace SDKSample
{
public partial class SeekStoryboardExample : Page
{
private void OnSliderValueChanged(object sender, RoutedEventArgs e)
{
int sliderValue = (int)SeekSlider.Value;
// Use the value of the slider to seek to a duration value of the Storyboard (in milliseconds).
myStoryboard.Seek(myRectangle, new TimeSpan(0, 0, 0, 0, sliderValue), TimeSeekOrigin.BeginTime);
}
}
}
