我刚刚开始尝试使用WPF模板与样式,我不知道我做错了什么.下面的目标是在菜单中替换选项的颜色.代码工作正常,但是当我复制并粘贴/重命名为“MenuChoiceOdd”的第二段时,我得到以下错误：
原文链接：https://www.f2er.com/windows/371488.html>在“System.Windows.Baml2006.TypeConverterMarkupExtension”上提供值提出异常.
代码示例：
<Window x:Class="WpfApplication1.Template_Testing"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Template_Testing" Height="300" Width="300">
<Grid>
<Grid.Resources>
<ControlTemplate x:Key="MenuChoiceEven">
<Border BorderThickness="1" BorderBrush="#FF4A5D80">
<TextBlock Height="Auto" HorizontalAlignment="Stretch" Margin="0" Width="Auto" FontSize="14" Foreground="SlateGray" TextAlignment="Left" AllowDrop="True" Text="{Binding Path=Content,RelativeSource={RelativeSource TemplatedParent}}">
<TextBlock.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="White" Offset="0" />
<GradientStop Color="#FFC2CCDB" Offset="1" />
</LinearGradientBrush>
</TextBlock.Background>
</TextBlock>
</Border>

<StackPanel Height="Auto" HorizontalAlignment="Stretch" Margin="2,0" Name="MenuChoicesStackPanel" VerticalAlignment="Top" Width="Auto">
<Button Template="{StaticResource MenuChoiceEven}" Content="Test Even menu element" />
<Button Template="{StaticResource MenuChoiceOdd}" Content="Test odd menu element" />
</StackPanel>
</StackPanel>
</Border>
</Grid>
</Window>
我究竟做错了什么？
