推荐答案

您可以轻松地做到这一点，但这只有在使用WPF时才很容易.在最简单的情况下，将视频放在某个父容器(一个面板)中.在其顶部，在同一面板中放置一些线对象.

它可能是System.Windows.Shapes.Line类的对象:

如果可能是其他Shape:

可选地，为了允许您自由地操纵形状的坐标和参数，可以将视频和形状放置在System.Windows.Controls.Canvas:
http://msdn.microsoft.com/en-us/library/system. windows.controls.canvas.aspx [ ^ ].

对于视频，您可以使用System.Windows.Controls.MediaElement的实例:

You can easily do it, but this is easy only if you use WPF. In simplest case, put video in some parent container, a panel. On top of it, put some line objects in the same panel.

It could be the object of the class System.Windows.Shapes.Line:
http://msdn.microsoft.com/en-us/library/system.windows.shapes.line.aspx[^].

If could be some other Shape:
http://msdn.microsoft.com/en-us/library/system.windows.shapes.shape.aspx[^].

Optionally, to allow you to freely manipulate coordinates and parameters of your shapes could be placing of video and shapes in System.Windows.Controls.Canvas:
http://msdn.microsoft.com/en-us/library/system.windows.controls.canvas.aspx[^].

For video, you would use the instance of System.Windows.Controls.MediaElement:
http://msdn.microsoft.com/en-us/library/system.windows.controls.mediaelement.aspx[^].
