样式的类型叫Style，它继承于DispatcherObject，它最重要的几个属性如下：
TargetType属性：这是一个类类型，也就是一个反射，这个属性指明了当前样式要作用于哪种类型的控件上。因为WPF中有许多的控件，我们定义一个样式时，必须要指明这个样式的“适用范围”。
BasedOn属性：样式也有继承的概念，所以，BasedOn指明了当前样式继承于哪个样式
Triggers属性：这是一个集合属性，表示触发器的定义，当满足某些条件时，触发哪些行为，以使控件达到一定的“节目效果”。比如当鼠标移上去时，控件的背景颜色变成红色。这些的效果就可以通过定义控件的触发器来设置。
Setters属性：这也是一个集合属性，样式是控件属性的值的“提前设置”，所以，我们对控件属性的值的设置都是以Setter条目的形式，一条一条的放到这个Setters集合中。
Resources属性：这个属性叫资源字典。在正式讲解样式之前，我们要先介绍一下资源字典的概念及其用途。它表示一些资源，以字典的形式进行维护，方便程序引用。
 
在FrameworkElement类就有一个Style属性。而所有的控件都继承于FrameworkElement基类，所以，我们只需要将定义好的样式赋值到控件的Style属性即可
在Application.Resources中定义样式
  1. <Application.Resources>
  2. <Grid>
  3. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  4.                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  5.    
  6. </ResourceDictionary><Button Content="文字块" Style="{StaticResource ButtonStyle}"/>
  7. </Grid><Grid>
  8. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  9.                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  10.    
  11. </ResourceDictionary><Button Content="文字块" Style="{StaticResource ButtonStyle}"/>
  12. </Grid>
  13. <Grid>
  14. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  15.                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  16.    
  17. </ResourceDictionary><Button Content="文字块" Style="{StaticResource ButtonStyle}"/>
  18. </Grid></Application.Resources>
复制代码
在XAML中引用样式
  1. <Grid>
  2. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  3.                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  4.    
  5. </ResourceDictionary><Button Content="文字块" Style="{StaticResource ButtonStyle}"/>
  6. </Grid>
复制代码
在引用样式时，我们有两种方式，分别是DynamicResource和StaticResource，后面再写上样式的名称。DynamicResource表示动态资源，StaticResource表示静态资源。这两者的区别是：静态资源在第一次编译后即确定其对象或值，之后不能对其进行修改。动态资源则是在运行时决定，当运行过程中真正需要时，才到资源目标中查找其值。因此，我们可以动态地修改它。由于动态资源的运行时才能确定其值，因此效率比静态资源要低。
 
资源字典与样式的用法
在项目中新建一个Style文件夹，右键-添加-资源字典文件。创建一个Button.xaml的资源文件，并在其中写下内容
  1. <Grid>
  2. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  3.                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  4.    
  5. </ResourceDictionary><Button Content="文字块" Style="{StaticResource ButtonStyle}"/>
  6. </Grid>
复制代码
资源文件都是以ResourceDictionary实例开头的对象，然后我们在其中编写了一个Style样式
回到项目的App.xaml文件中，编写如下内容
  1. <Application.Resources>
  2. <Grid>
  3. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  4.                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  5.    
  6. </ResourceDictionary><Button Content="文字块" Style="{StaticResource ButtonStyle}"/>
  7. </Grid><Grid>

  9.                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  10.    
  11. </ResourceDictionary><Button Content="文字块" Style="{StaticResource ButtonStyle}"/>

我们在Application的Resources属性中实例化了一个ResourceDictionary对象，并在其中定义了两个SolidColorBrush对象，一个style样式，以及在MergedDictionaries集合中添加了一个ResourceDictionary对象，其数据源指向了Button.xaml资源文件。

Resources属性的值只能是一个ResourceDictionary对象，一个ResourceDictionary对象中可以定义多个资源。如果有多个ResourceDictionary对象，则必须使用MergedDictionaries属性。任意类型都可以在Resources中被实例化，但是必须在实例化时指明一个key，因为在xaml中要引入定义好的资源，都是以key进行查找的。
