WPF - 以编程方式更改样式，"can't find style"

Question

异常消息：

System.Windows.ResourceReferenceKeyNotFoundException：找不到"｛StaticResource style1｝"资源

C#代码：

private void Button_Click(object sender, RoutedEventArgs e)
{
Button newBtn = new Button();
newBtn.Height = 30;
//newBtn.Style = Resources["style1"] as Style;
newBtn.Style = (Style)FindResource("{StaticResource style1}");
stackpanel1.Children.Add(newBtn);
}

XAML代码：

<Grid.Resources>
<Style x:Key="style1" TargetType="{x:Type Button}">

.....styleofbutton
</Style>
</Grid.Resources>

<Button Content="Button" HorizontalAlignment="Left" Style="{StaticResource style1}" Margin="128,98,0,0" VerticalAlignment="Top" Width="159" Height="61" Click="Button_Click"/>
<StackPanel x:Name="stackpanel1" HorizontalAlignment="Left" Height="292" Margin="348,72,0,0" VerticalAlignment="Top" Width="395"/>

newBtn在XAML代码中找不到我的样式。我做错了什么？

Answer 1

资源的键只是"style1"：

newBtn.Style = (Style)FindResource("style1");

您还应该将Style移动到<Window.Resources>，或者在Grid:中查找它

newBtn.Style = theNameOfTheGrid.Resources["style1"] as Style;
