推荐答案

MSDN写道：

Windows Presentation Foundation（WPF）发货许多常见的UI组件几乎在每个Windows应用程序中都使用，例如Button，Label，TextBox，Menu和ListBox。 从历史上看，这些对象被称为控件。 虽然WPF SDK继续使用术语控件来松散地表示在应用程序中表示可见对象的任何类 ，重要的是要注意，类不需要从Control类继承以具有可见的存在。从Control类继承的类包含ControlTemplate，它允许控件的使用者从根本上更改控件的外观，而无需创建新的子类。本主题讨论如何在WPF中常用控件（包括从Control类继承的控件和那些不从控件类继承的控件）。

Windows Presentation Foundation (WPF) ships with many of the common UI components that are used in almost every Windows application, such as Button, Label, TextBox, Menu, and ListBox. Historically, these objects have been referred to as controls. While the WPF SDK continues to use the term "control" to loosely mean any class that represents a visible object in an application, it is important to note that a class does not need to inherit from the Control class to have a visible presence. Classes that inherit from the Control class contain a ControlTemplate, which allows the consumer of a control to radically change the control's appearance without having to create a new subclass. This topic discusses how controls (both those that do inherit from the Control class and those that do not) are commonly used in WPF.
