在画布上查找控件位置 [英] Find control position on canvas

问题描述

我有一个画布，其中包含一些文本块，我需要找到顶部，左角点，我在xaml分配它们。如何获得这两个属性？当我在画布上的框架元素循环时，我似乎找不到那些列出的属性。

I have a canvas which contains a few textblocks and I need to find the top, left corner points that I assigned them in xaml. How can I get those two properties? When I loop through the framework elements on the canvas I can't seem to find those to properties listed.

推荐答案

如何获取值：

foreach(FrameworkElement fe in canvas.Children){

   // example 0
   double top=(double)fe.GetValue(Canvas.TopProperty);
   double left=(double)fe.GetValue(Canvas.LeftProperty);

   // example 1
   double top1=Canvas.GetTop(fe);
   double left1=Canvas.GetLeft(fe);

}
