如何加载自定义静态资源

Question

我有两个文件: ButtonStyle.xaml和ConstantsStyle.xaml

在App.xaml中，我将初始化

    <Application.Resources>        
            <ResourceDictionary>
                <ResourceDictionary.MergedDictionaries>
                    <ResourceDictionary Source="/Zalo;component/ResourceDictionary/480x800/ConstantsStyle.xaml"/>
                    <ResourceDictionary Source="/Zalo;component/ResourceDictionary/480x800/ButtonStyle.xaml"/>
                 </ResourceDictionary.MergedDictionaries>
            </ResourceDictionary>
......
    </Application.Resources>

文件ConstantsStyle.xaml

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    
    xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows">

    <Thickness x:Key="GenericButtonStylePadding">0,7</Thickness>

</ResourceDictionary>

文件ButtonStyle.xaml

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
    xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit" 
    xmlns:usercontrols="clr-namespace:Zalo.UserControls">

    <Style x:Key="GenericButtonStyle" TargetType="Button">
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="Padding" Value="{StaticResource GenericButtonStylePadding}"/>
   </Style>

</ResourceDictionary>

应用程序崩溃运行时。因为找不到名称/密钥为GenericButtonStylePadding的资源？

如何正确运行app？请帮帮我

Answer 1

尝试使用DyanamicResource而不是StaticResource

<Style x:Key="GenericButtonStyle" TargetType="Button">
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="Padding" Value="{DynamicResource GenericButtonStylePadding}"/>
   </Style>

编辑:你可以测试一件事。向Constant.XAML添加另一个常量

<Brush x:Key="BGBrush">Black</Brush>

试着在你的ButtonStyle.XAML中使用它

<Style x:Key="GenericButtonStyle" TargetType="Button">
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="Width" Value="200"></Setter>
        <Setter Property="Background" Value="{StaticResource BGBrush}"></Setter>
    </Style>

查看按钮背景是否变为黑色。如果颜色在变化，那么可以尝试厚度之外的其他颜色。
