在C#中绘制所有非客户区域

问题描述

例如，我正在寻找用C#绘制非客户区域的方法，而不是矩形作为表单，我想要一个椭圆形(这是一个例子)，但是我该怎么做呢?

I am looking to draw my non-client area in C#, for example, instead a rectangle as a form, i want an ellipse (this is an example), but how can i do it?

我基本上想绘制我所有的非客户区域，并且我想这样做必须重写一些方法，但是哪些方法呢?

I basically want to draw all my non client area, and i think to do that i will have to override some methods, but which ones?

我找到了一个使用'xaml'的示例，我认为这是Windows Presentation Foundation应用程序，但是我不太了解.

I have found an example that uses 'xaml', what i think that is windows presentation foundation app, but i haven't understand it well.

推荐答案

对于WinForms，您需要处理WM_NCPAINT消息(覆盖Control.WndProc)并启用分层窗口样式，以便在边界框中具有透明区域.

For WinForms, you'll need to process the WM_NCPAINT message (override Control.WndProc) and also enable the layered window style in order to have transparent regions in the bounding box.
