解决方案

在这种情况下，您将不得不编写您自己的Treeview实现.创建一个新的customcontrol并从treeview继承.覆盖OnPaintBackground

现在在Windows窗体中实际上没有什么比透明的背景色更好.该框架在这里有一些技巧.如果将控件的背景设置为透明，它将继承其父控件的OnPaintBackground实现(不确定如何以代码方式实现)，以模拟透明外观.

希望我能给您一个解决问题的方法.我认为您首先必须在这里和那里阅读有关如何处理OnPaintBackground的内容(如果它确实存在于树视图中；否则应为OnPaint)

解决方案

I that case you will have to write your own implementation of the treeview. Create a new customcontrol and inherit from treeview. override the OnPaintBackground

Now in windows forms there is actually nothing like transparent background color. The framework does a little trick here. If you set the background of a control to transparent it will inherit the OnPaintBackground implementation (am not really sure how this is done codewise) of its parent to simulate a transparent look.

Hope that I could give you an idea how to solve your problem. I think you will have to read first some here and there on how to handle the OnPaintBackground (if it actually exists for a treeview; otherwise the OnPaint)
