推荐答案

控件具有充当窗口所需的所有管道。响应窗口消息（WndProc）并具有最重要的Handle的能力。组件缺少所有这些。这真的很简单，它具有设计时支持设置属性的能力，就这样就可以了。

A Control has all the plumbing required to act as a window. The ability to respond to Window messages (WndProc) and having a Handle being foremost. Component is missing all that. It is really rather simple, it has design time support to set properties and it can be disposed, that's all.

组件仍然可以具有运行时表示形式，OpenFileDialog是最好的例。但这实际上是Windows内置的对话框，而不是Windows窗体。

Components still can have a runtime representation, OpenFileDialog being the best example. But that is actually a dialog built into Windows, not Windows Forms.
