WPF XAML 为项目设置全局样式

全局资源样式属性

App.xaml

<Application.Resources> <ResourceDictionary><br> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Dictionary.xaml"/> </ResourceDictionary.MergedDictionaries><br> <Style x:Key="xxx" TargetType="Button"> <Setter Property="Foreground" Value="White"></Setter> <Setter Property="FontSize" Value="30"></Setter> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Grid></Grid> </ControlTemplate> </Setter.Value> </Setter></Style> <ControlTemplate x:Key="xx" TargetType="Button"> <Grid></Grid> </ControlTemplate> </ResourceDictionary></Application.Resources>

说明：

1.行类属性尽量少用，只有特殊控件 需要用到行内属性，

   正确的做法是封装统一风格的所有控件。
  （例如按钮，统一高宽，字体，字体大小，然后申明到独立的资源字典中，
    在App.xaml中引用）

2.头部资源引用情况用于 不同 Window 适应不同主题或者风格的情况。

   比如为某一个窗口申明一个当前窗口单独使用的样式。

  （例如播放器的旋转控件，只有一个页面用到，只需要在Window级引用对应资源字典）

   不放在App.xaml原因是为了降低内存消耗。

3.App.xaml 里面的资源引用适用于全局资源。理论上每一个被申明的Window
   都会创建一个对应资源字典的实例。除非是每个Window都会用到的模块，
    不然建议放到对应Window级
