What is a component? What are controls? What is the difference between the two?

Thank you

One has an interface, one does not, ^ _ ^

Don't slap these two words, look at specific things, what you want to say is what it is.

Component = 1 group of controls
Don't understand

Component refers to some dynamic link libraries. The code we usually write can directly compile and produce .exe executable files. At the same time, it can also generate dll components. The advantage of producing dll components is that they can call the functions in dll in another program. This is useful for implementing modular software Great help in development

Controls (for ASP.net) Controls in asp.net can be understood as some powerful web page elements such as: text input boxes, buttons, tables, etc. Asp.net is divided into html controls and web controls.
  htmlspaces (htmlcontrols) are mainly executed in the foreground and webcontrols (webcontrols) are mainly executed in the background
 Several controls can be combined together to form a user-defined control with its own functions

A component is a class that implements an interface or a class derived directly or indirectly. It is usually used for reusable objects and can interact with other objects.
Controls are components that provide (or implement) user interface (UI) functionality.
Each control is a component, but not every component is a control.

Basically understandable on asp.net:

Component. The main emphasis is on features rather than interfaces. Page is also a component, often used in HttpHandler.ProcessRequst, HttpServer.Execute and other places.

Controls-webControl, htmlControl, userControl, or component with a more obvious interface performance at runtime.

A control is a special component.

A control is a special component. -----error
Component = 1 group of controls --------------- too general

A control is a component, not special, every control is a component

If the class you develop is called a component according to everyone's standards, it can be called a component. This is the same no matter which language.

A control is actually a component. In my impression, it should refer to a component with an interface. As for whether it is a special component, it's up to you. I don't think it is special or not. The key is whether you understand it.

In my opinion, when you think components and controls can be mixed, you understand it.
