下面的文本块自动收报机动画一点也不流畅。所以需要一些关于如何使这个双重动画更流畅以获得更多用户友好性的指导，因为在那之后我将在那里集成 RSS 新闻提要。

XAML 代码：

<Window x:Class="Wpf_Marquee.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:Wpf_Marquee"
    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525">

<Canvas Margin="50" Canvas.Left="150" Canvas.Top="100" ClipToBounds="True" Name="canMain" Background="Red"   Height="100" Width="400" >  

    <TextBlock x:Name="marquee"  Margin="0 50 0 0" FontSize="20pt" Foreground="Black" Background="Transparent" Canvas.Left="0" Canvas.Right="68">

        Hello This is a Sample Marquee in Wpf. Please check the animation

    </TextBlock>

    <Button x:Name="btn1" Width="50" Height="50" Content="Marquee" Click="Button_Click"   />
</Canvas>

我的 .CS 代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel.Syndication;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Automation.Peers;
using System.Windows.Automation.Provider;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Xml;


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

    }
    public void Button_Click(object sender, RoutedEventArgs e)
    {


        DoubleAnimation doubleAnimation = new DoubleAnimation();
        doubleAnimation.From = this.ActualWidth;
        doubleAnimation.To = -marquee.ActualWidth;
        doubleAnimation.RepeatBehavior = RepeatBehavior.Forever;
        doubleAnimation.Duration = new Duration(TimeSpan.FromSeconds(2060)); // provide an appropriate  duration 
        marquee.BeginAnimation(Canvas.LeftProperty, doubleAnimation);
    }


}
}

在此先感谢您的帮助 ：）
