Question

我在WPF主题上遇到了一个奇怪的错误：Cannot resolve all property references in the property path '(0).(1).(2)[0].X' 我已将其追溯到我的进度栏了。

    <Style x:Key="ProgressBarStyle"

<SolidColorBrush x:Key="ProgressBarBackgroundBrush"
                 Color="{StaticResource Color_005}" />
<SolidColorBrush x:Key="ProgressBarForegroundBrush"
                 Color="{StaticResource Color_024}" />
<LinearGradientBrush x:Key="ProgressBarIndeterminateBackgroundBrush"
                     EndPoint="0,1"
                     MappingMode="Absolute"
                     SpreadMethod="Repeat"
                     StartPoint="20,1"
                     Opacity="0.8">
    <LinearGradientBrush.Transform>
        <TransformGroup>
            <TranslateTransform X="0" />
            <SkewTransform AngleX="-30" />
        </TransformGroup>
    </LinearGradientBrush.Transform>
    <GradientStop Color="{StaticResource Color_023}"
                  Offset="0.249" />
    <GradientStop Color="{StaticResource Color_024}"
                  Offset=".25" />
    <GradientStop Color="{StaticResource Color_024}"
                  Offset="0.75" />
    <GradientStop Color="{StaticResource Color_023}"
                  Offset="0.751" />
</LinearGradientBrush>

现在我可以看到DoubleAnimation.Storyboard.TargetProperty以及对LinearGradientBrush ProgressBarIndeterminateBackgroundBrush转换的引用。但它看起来不错＃39;我对你的理解很明显！

我能够重现您的情况，只需将(Shape.Fill)更改为(Rectangle.Fill)似乎就可以解决问题。
