推荐答案

<您好Groboto，

Hi Groboto,

您可以通过以下代码将协调元素转换为屏幕协调。

You could translate element coordinated to screen coordinated via the following code.

void MainWindow_TouchDown(object sender, TouchEventArgs e)
{

    TouchPoint pointFromWindow = e.GetTouchPoint(this); //relative to Top-Left corner of Window

    Point locationFromScreen = this.PointToScreen(new Point(pointFromWindow.Position.X, pointFromWindow.Position.Y)); //translate to coordinates relative to Top-Left corner of Screen

}
