将C#转换为C#WPF ......... [英] Converting C# to C# WPF............

问题描述

这是我的代码

this is my code

panel.Bounds.Contains(MousePosition);

can some one please conver this code into C# WPF code?

推荐答案

没有C#与C#WPF — C#是C#.没有转换" —库是不同的并且做不同的事情.

现在，我想您只需要对照面板的边界矩形检查鼠标坐标即可.问题是:您在哪个坐标系中具有MousePosition?如果从此控件的事件中获取了鼠标坐标，则返回始终为true；否则，返回true.如果鼠标位置是屏幕坐标，则使用System.Windows.Media.Visual.PointToScreen将矩形(0，0)，(ActualWidth，ActualHeight)的角点计算为屏幕坐标，并比较鼠标位置；或者，使用System.Windows.Media.Visual.PointFromScreen计算鼠标在控件坐标系中的位置.很简单.

当您可以使用点击测试时，您不必这样做.参见:

There is not C# vs C# WPF — C# is C#. There is no "convert" — the libraries are different and do different things.

Now, I guess you simply need to check mouse coordinate against panel''s bounding rectangle. The question is: in what coordinate system do you have MousePosition? If you got the mouse coordinates from the event of this control, the return is always true; if you have mouse position is screen coordinates, use System.Windows.Media.Visual.PointToScreen to calculate corner points of the rectangle (0, 0), (ActualWidth, ActualHeight) into screen coordinates and compare the mouse position; alternatively, calculate mouse position in the control''s coordinate system using System.Windows.Media.Visual.PointFromScreen. Simple enough.

You don''t have to do this when you can use hit tests. See:
