XAML

2020-07-09 15:56:12

XAML（Extensible Application Markup Language i/ˈzæməl/)是Windows Presentation Foundation（WPF）的一部分，是微软开发的一种基于XML、基于声明，用于初始化结构化值和对象的用户界面描述语言，它有着HTML的外观，又揉合了XML语法的本质，例如：可以使用<Button>标签设置按钮（Button）。它类似Linux平台下的glade。至于WinFX XAML Browser Application（XBAP）是用XAML作界面描述，在浏览器中运行的程序，可取代过去的ActiveX、Java Applet、Flash。

XAML本质上属于一种.NET编程语言，属于通用语言运行库（Common Language Runtime），同C#、VB.NET等同。与HTML类似，特点是用来描述用户界面。XAML的语法格式为：<Application... />，Application是必备的基本元素。XAML可以定义2D和3D对象、旋转（rotations）、动画（animations），以及各式各样的效果。
