对整个WPF项目进行样式修改时，采用全局样式的方法。
首先，建一个xaml文件为存放样式的资源文件。写入想修改的控件样式，以滚动条样式为例。
1 <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 2 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 3 xmlns:sys="clr-namespace:System;assembly=mscorlib"> 4

</ControlTemplate.Triggers> 233 </ControlTemplate> 234 </Setter.Value> 235 </Setter> 236 </Style> 237 238 239 </ResourceDictionary>
然后，在App.xaml里添加对资源文件的引用，<ResourceDictionary Source="pack://application:,,,/Resource/Scroll.xaml"/>。
最后，将控件样式修改为自定义样式， <Style TargetType="ScrollBar" BasedOn="{StaticResource for_scrollbar}"/>
<Style TargetType="ScrollViewer" BasedOn="{StaticResource for_scrollviewer}"/>。
这样整个项目中的控件就会都变成自己想要的样式了。
