使用DragMove移动窗口超过Windows上边缘时, 窗口会自动跳到新的显示位置.

mkdir TestWpf
cd TestWpf
dotnet new sln
dotnet new wpf -o src\TestWpf
dotnet sln add src\TestWpf\TestWpf.csproj

public partial class MainWindow
{
    public MainWindow()
    {
        InitializeComponent();

        MouseLeftButtonDown += MainWindow_MouseLeftButtonDown;
    }

    private void MainWindow_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        DragMove();
    }
}
