一.Application介绍 WPF和WinForm 很相似, WPF与WinForm一样有一个 Application对象来进行一些全局的行为和操作,并且每个 Domain (应用程序域)中仅且只有一个 Application 实例存在。和 WinForm 不同的是WPF Application默认由两部分组成 : App.xaml 和 App.xaml.cs,这有点类似于 Asp.Net WebForm,将定义和行为代码相分离。 微软把WPF中经常使用的功能都封装在 Application 类中了。 Application 类具体有以下功能: 跟踪应用程序的生存期并与之交互。 检索和处理命令行参数。 检测和响应未经处理的异常。 共享应用程序范围的属性和资源。 管理独立应用程序中的窗口。 跟踪和管理导航。 二.WPF应用程序的启动 关于如何在Visual Studio中创建一个“WPF应用程序”,前面的文章中已经说过了。请参见 WPF入门教程系列一——基础 。 1、在Visual Studio 2013中创建一个“WPF应用程序”,使用App.xaml文件定义启动应用程序。XAML从严格意义上说并不是一个纯粹的 XML 格式文件,它更像是一种 DSL(Domain Specific Language,领域特定语言),它的所有定义都会由编译器最后编译成代码。App
