答案 0 :(得分：0)
您可以使用动态资源来实现：1）声明资源
2）在属性中使用它（作为动态资源，而不是静态）
3）在后面的代码中更改资源< / p>
<Grid x:Name="myGrid">
<Grid.Resources>
<system:Double x:Key="myFontSize">50</system:Double>
<FontFamily x:Key="myFontFamily">Arial</FontFamily>
</Grid.Resources>
<TextBlock FontFamily="{DynamicResource myFontFamily}" FontSize="{DynamicResource myFontSize}">Hello World</TextBlock>
<Button Height="50" Click="Button_Click">Change font</Button>
</Grid>
private void Button_Click(object sender, RoutedEventArgs e)
{
myGrid.Resources["myFontSize"] = (double)99;
myGrid.Resources["myFontFamily"] = new FontFamily("Verdana");
}
P.S。最好使用MVVM。
