我正在做一个音乐项目。您知道，如果您需要，我们必须有一个搜索栏来搜索 MediaElement 的位置。但是当滑块（搜索栏）运行时，IDE 抛出异常说：Exception:Thrown: Slider TargetType does not match type of element Control。我不认为这个问题是由代码引起的，我认为它是在我为搜索栏设计滑块时出现的。请帮助我！对不起我的英语不好。这是代码：

<Style x:Key="MyCustomStyleForSlider" TargetType="{x:Type Slider}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Slider}">
                <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto"/>
                            <RowDefinition Height="Auto" MinHeight="{TemplateBinding MinHeight}"/>
                            <RowDefinition Height="Auto"/>
                        </Grid.RowDefinitions>
                        <TickBar x:Name="TopTick" Visibility="Collapsed" Fill="{TemplateBinding Foreground}" Placement="Top" Height="4" Grid.Row="0"/>
                        <TickBar x:Name="BottomTick" Visibility="Collapsed" Fill="{TemplateBinding Foreground}" Placement="Bottom" Height="4" Grid.Row="0"/>
                        <Border x:Name="TrackBackground"  BorderThickness="1" CornerRadius="1" Margin="5,0" VerticalAlignment="Center" Height="4.0" Grid.Row="1" >
                            <Canvas Margin="-6,-1">
                                <Rectangle Visibility="Hidden" x:Name="PART_SelectionRange" Height="4.0" Fill="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" Stroke="{DynamicResource {x:Static SystemColors.ControlDarkDarkBrushKey}}" StrokeThickness="1.0"/>
                            </Canvas>
                        </Border>
                        <Track x:Name="PART_Track" Grid.Row="1">
                            <Track.DecreaseRepeatButton>
                                <RepeatButton Command="{x:Static Slider.DecreaseLarge}"/>
                            </Track.DecreaseRepeatButton>
                            <Track.IncreaseRepeatButton>
                                <RepeatButton Command="{x:Static Slider.IncreaseLarge}"/>
                            </Track.IncreaseRepeatButton>
                            <Track.Thumb>
                                <Thumb x:Name="Thumb" Background="Black"/>
                            </Track.Thumb>
                        </Track>
                    </Grid>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

检查您创建的任何样式或控件模板上的 TargetType 属性，并确保它适合您应用样式/控件模板的控件类型。
