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.
