Question

我主要基于C＃代码编写WPF类库，而我目前正在尝试仅为样式化UI元素加载XAML文件。

这是XAML＆＃34;风格＆＃34;代码与＆＃34; BuildAction：内容＆＃34; ：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:local="clr-namespace:WpfApplication1">
<Style x:Key="LabelStyle" TargetType="{x:Type Label}">
    <Setter Property="Height" Value="53" />
    <Setter Property="Width" Value="130" />
    <Setter Property="HorizontalAlignment" Value="Left" />
    <Setter Property="Margin" Value="99,71,0,0" />
    <Setter Property="VerticalAlignment" Value= "Top" />
    <Setter Property="Foreground" Value="#FFE75959" />
    <Setter Property="FontFamily" Value="Calibri" />
    <Setter Property="FontSize" Value="40" />
</Style>

以下是我的标签代码：

    private void CreateElement(int i)
    {
        UIElementOut[i] = new Label();
        var uiElement = (Label)UIElementOut[i];
        uiElement.HorizontalAlignment = HorizontalAlignment.Center;
        uiElement.VerticalAlignment = VerticalAlignment.Center;
        uiElement.FontFamily = new FontFamily(FFontInput[i]);
        uiElement.FontSize = Convert.ToDouble(FontSizeIn[i]);
        uiElement.Content = TextIn[i];
        Brush BgBrushColor = new SolidColorBrush(RGBAToMediaColor(FBgCol[i]));
        Brush FgBrushColor = new SolidColorBrush(RGBAToMediaColor(FFgCol[i]));
        uiElement.Background = BgBrushColor;
        uiElement.Foreground = FgBrushColor;

        Uri uri = new Uri("pack://application:,,,/WpfApplication1;component/WpfApplication1/Styles/LabelStyle.xaml", UriKind.Relative);

        StreamResourceInfo info = Application.GetContentStream(uri);
        System.Windows.Markup.XamlReader reader = new System.Windows.Markup.XamlReader();
        ResourceDictionary myResourceDictionary = Application.LoadComponent(uri) as ResourceDictionary;
        Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);
        Style myLabelStyle = myResourceDictionary["LabelStyle"] as Style;
        uiElement.Style = myLabelStyle;
    }

如果UriKind设置为＆＃34;相对＆＃34;我收到此错误消息：

A relative URI cannot be created because the 'uriString' parameter represents an absolute URI.

但是如果Urikind被设置为＆＃34; Absolute＆＃34;然后我得到了这个：

Cannot use absolute URI.

因此，无论如何，未加载XAML文件且未应用样式。

编辑：

我试过这个URI：

pack://application:,,,/WpfApplication1;component/Styles/LabelStyle.xaml

并得到同样的错误。

更正位于本地程序集项目文件夹

子文件夹中的资源文件的格式

pack://application:,,,/Subfolder/ResourceFile.xaml

在单独引用的程序集中引用资源文件的正确格式为

pack://application:,,,/ReferencedAssembly;component/Subfolder/ResourceFile.xaml

将你的uri改为

pack://application:,,,/WpfApplication1;component/Styles/LabelStyle.xaml

应解决问题

WPF类库，加载带有绝对URI或相对URI的XAML都不起作用
