请告诉我，我如何在鼠标点击上类似地替换命令TouchPoint ?我添加了我必须更改的代码:

 private Dictionary<int, UIElement> myEllipses =
        new Dictionary<int, UIElement>();
 private void cnv_MouseDown(object sender, MouseButtonEventArgs e)
    {
        Ellipse ellipse = new Ellipse();
        ellipse.Width = 30;
        ellipse.Height = 30;
        ellipse.Stroke = Brushes.White;
        ellipse.Fill = Brushes.Gold;

        TouchPoint tp = e.GetPosition(cnv);
        Canvas.SetTop(ellipse, tp.Bounds.Top);
        Canvas.SetLeft(ellipse, tp.Bounds.Left);
        myEllipses[e.TouchDevice.Id] = ellipse;

        cnv.Children.Add(ellipse);
    }

如何更换触点上的鼠标点击

尝试GetPosition()方法获取鼠标被点击的点。试试这个:

private void cnv_MouseDown(object sender, MouseButtonEventArgs e)
{
    Point clickedPt = e.GetPosition(this);
    var xPos = clickedPt.X;
    var yPos = clickedPt.Y;
}
