静态资源(StaticResource)和动态资源(DynamicResource)
一、文章概述
本演示介绍了WPF的静态资源和动态资源的基本使用,并对两者做了简单的比较。
二、定义并使用资源
- <Window x:Class="Demo010.MainWindow"
- xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
- xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
- Title="MainWindow" Height="149" Width="296">
- <Window.Resources>
- <TextBlock x:Key="Res1" Text="海上生明月" />
- <TextBlock x:Key="Res2" Text="海上生明月" />
- </Window.Resources>
- <StackPanel>
- <Button Margin="5,5,5,0" Content="{StaticResource Res1}" />
- <Button Margin="5,5,5,0" Content="{DynamicResource Res2}" />
- <Button Margin="5,5,5,0" Content="Update" Click="UpdateRes_Click" />
- </StackPanel>
- </Window>
二、更新资源内容
- private void UpdateRes_Click(object sender, RoutedEventArgs e)
- {
- this.Resources["Res1"] = new TextBlock() { Text = "天涯共此时" };
- this.Resources["Res2"] = new TextBlock() { Text = "天涯共此时" };
- }
三、更新资源前后的变化
