The problem is because of incorrect order of your styles. I mean that if we publish button style with referrance on static resource NormalBrush, which is declared under the style, like this:

问题是因为您的样式顺序不正确。我的意思是，如果我们在静态资源 NormalBrush 上发布带有引用的按钮样式，该样式在样式下声明，如下所示：

 <Style TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border Background="{StaticResource NormalBrush}" >
                    <ContentPresenter Name="ButtonCont"></ContentPresenter>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>       
</Style>

<LinearGradientBrush x:Key="NormalBrush" StartPoint="0,0" EndPoint="0,1">
    <GradientBrush.GradientStops>
        <GradientStopCollection>
            <GradientStop Color="#FFF" Offset="0.0"/>
            <GradientStop Color="#CCC" Offset="1.0"/>
        </GradientStopCollection>
    </GradientBrush.GradientStops>
</LinearGradientBrush>

This code will give you such error. But if you change, like this

这段代码会给你这样的错误。但如果你改变，像这样

<LinearGradientBrush x:Key="NormalBrush" StartPoint="0,0" EndPoint="0,1">
    <GradientBrush.GradientStops>
        <GradientStopCollection>
            <GradientStop Color="#FFF" Offset="0.0"/>
            <GradientStop Color="#CCC" Offset="1.0"/>
        </GradientStopCollection>
    </GradientBrush.GradientStops>
</LinearGradientBrush>

 <Style TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border Background="{StaticResource ButtonBackground}" >
                    <ContentPresenter Name="ButtonCont"></ContentPresenter>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>       
</Style>

Everything works fine. The same this occures if your resources are stored in different xaml files and you attach them in your ResourceDictionary. For example (cosider we store our NormalBrush in Colors.xaml and Button in Button.xaml). This gives error:

一切正常。如果您的资源存储在不同的 xaml 文件中并将它们附加到您的 ResourceDictionary 中，也会发生同样的情况。例如（考虑到我们将 NormalBrush 存储在 Colors.xaml 中，将 Button 存储在 Button.xaml 中）。这给出了错误：

<ResourceDictionary Source="Resources\Button.xaml" />
<ResourceDictionary Source="Resources\Colors.xaml" />

This should work error:

这应该工作错误：

<ResourceDictionary Source="Resources\Colors.xaml" />
<ResourceDictionary Source="Resources\Button.xaml" />

Please check if you have specified a converter in a Xaml that doesn't exist.

请检查您是否在 Xaml 中指定了不存在的转换器。

I had stumbled upon this exact problem. There is a problem with the XAML file. SolidBorderBrushis missing from the XAML. By adding it, the sample works fine.

我偶然发现了这个确切的问题。XAML 文件存在问题。 SolidBorderBrushXAML 中缺少。通过添加它，示例工作正常。

<SolidColorBrush x:Key="SolidBorderBrush" Color="#000" />

Bellow follows the complete contents of the XAML file.

By using a DynamicResourceinstead of StaticResource, it will find the resource at runtime, so you don't have to worry about the order of the declarations in the XAML.

通过使用DynamicResource替代StaticResource，它将在运行时找到资源，因此您不必担心 XAML 中声明的顺序。

There may be downsides to this (?), but in particularly sticky cases, this has been the answer to my prayers.

这可能有缺点（？），但在特别棘手的情况下，这一直是我祈祷的答案。

Check the permission for your resource.resx file. At top of your file you will find the dropdown known as Access Modifier : change its type to 'Public'

检查您的 resource.resx 文件的权限。在文件顶部，您会找到名为 Access Modifier 的下拉菜单：将其类型更改为“Public”
