c# - 全局资源未将样式应用于 xaml 中的控件

Question

我为 ProgressBar 声明了以下样式在App.xaml

                            <Trigger Property="IsIndeterminate"
                             Value="false">
                                <Setter TargetName="Animation"
                                Property="Background"
                                Value="#80B5FFA9"/>
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
</Application.Resources>

如您所见 <Style x:Key="{x:Type ProgressBar}" TargetType="{x:Type ProgressBar}">已经提到过，据我所知，这应该适用于所有 ProgressBar在应用程序中。

我有以下ProgressBar在Login.xaml页面，此内容保存在 View 下文件夹。

<ProgressBar Name="LoginProgress" Minimum="0" Maximum="100" HorizontalAlignment="Left" 
 Height="24" Margin="99,124,0,0" VerticalAlignment="Top" Width="109" 
 Style="{DynamicResource {x:Type ProgressBar}}">

</ProgressBar>

我还含蓄地提到了Style ProgressBar 的属性。毕竟，这种风格还没有得到应用。搜索了谷歌中的所有页面，但无法完全获得适当的资源来理解，因此来到这里。谁能让我知道或提供更多有关如何完成此操作的见解？
