Answer 1

我正在使用页面，但您也可以使用窗口。

第一。创建两个页面 LeftPage.xaml 和 RightPage.Xaml 以及 MainWindow.xaml 和 MainWindows.xaml.cs 的以下代码

XAML

主窗口

<Window x:Class="SOWPF.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:SOWPF"
    mc:Ignorable="d" 
    Title="MainWindow" Height="450" Width="800"
    MouseDown="Window_MouseDown" MouseMove="Window_MouseMove">
<Grid>
    <Frame x:Name="MainFrame" NavigationUIVisibility="Hidden" />
</Grid>

C#

public partial class MainWindow : Window
{
    protected Point SwipeStart;
    public MainWindow()
    {
        InitializeComponent();
        MainFrame.Source = new Uri("LeftPage.xaml", UriKind.RelativeOrAbsolute);
    }

    private void Window_MouseDown(object sender, MouseEventArgs e)
    {
        SwipeStart = e.GetPosition(this);
    }

    private void Window_MouseMove(object sender, MouseEventArgs e)
    {
        if (e.LeftButton == MouseButtonState.Pressed)
        {
            var Swipe = e.GetPosition(this);                

            //Swipe Left
            if (SwipeStart != null && Swipe.X > (SwipeStart.X + 200))
            {
                // OR Use Your Logic to switch between pages.
                MainFrame.Source = new Uri("LeftPage.xaml", UriKind.RelativeOrAbsolute);
            }

            //Swipe Right
            if (SwipeStart != null && Swipe.X < (SwipeStart.X - 200))
            {
                // OR Use Your Logic to switch between pages.
                MainFrame.Source = new Uri("RightPage.xaml", UriKind.RelativeOrAbsolute);
            }
        }
        e.Handled = true;
    }
}
