WPF基础入门

Class8-资源基础

前言：方便各种资源的集中管理和动态效果
静态引用：初始化的时候确定样式，后续不发生改变
动态引用：样式随着引用的内容一起改变
1、新建资源字典.xaml，创建一个边框颜色资源MyBrush和一个button的style

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"><Style x:Key="DefaultButtonStyle" TargetType="Button"><Setter Property="Foreground" Value="Red"></Setter><Setter Property="FontSize" Value="15"></Setter></Style><SolidColorBrush x:Key="MyBrush" Color="Yellow"/></ResourceDictionary>

2、在App.xaml中引入资源字典

<Application.Resources><!--引入资源字典--><ResourceDictionary><ResourceDictionary.MergedDictionaries><ResourceDictionary Source="Resources/ButtonStyle.xaml"></ResourceDictionary></ResourceDictionary.MergedDictionaries></ResourceDictionary></Application.Resources>

3、新建一个页面.xaml

<Window x:Class="WPF_Learn.Class_10_资源基础"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:local="clr-namespace:WPF_Learn"mc:Ignorable="d"Title="Class_10_资源基础" Height="450" Width="800"><!--在App.xaml里面引入资源字典--><Grid><StackPanel><Button Content="点击我触发Test_Click" Click="Test_Click" Style="{StaticResource DefaultButtonStyle}"></Button><Button Content="静态引用，不会发生改变" Margin="0,5,0,5" BorderBrush="{StaticResource MyBrush}"></Button><Button Content="动态引用，点击按钮MyBrush改变后样式跟着改变" BorderBrush="{DynamicResource MyBrush}"></Button></StackPanel></Grid>
</Window>

 private void Test_Click(object sender, RoutedEventArgs e){// 资源的动态改变 静态引用在初始化的时候固定this.Resources["MyBrush"] = new SolidColorBrush(Colors.Blue);//寻找资源字典//var solidColor = App.Current.FindResource("SolidColor");//var style = App.Current.FindResource("DefaultButtonStyle");}
