使用ResourceDictionary導致找不到資源“xxx”

我目前正在嘗試通過在有意義時將其拆分為多個檔案來組織我的 UI Xaml。

因此，我將我的 TitleBar 樣式匯出到一個額外的檔案 ( \UI\Styles\TitleBarButtonStyles.xaml) 中：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<Style x:Key="TitleBarButton" TargetType="{x:Type Button}">
    <Setter Property="BorderThickness" Value="0,0,0,0" />
    <Setter Property="Height" Value="18" />
    <Setter Property="Width" Value="18" />
    <Setter Property="WindowChrome.IsHitTestVisibleInChrome" Value="True" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" Background="{TemplateBinding Background}" CornerRadius="10">
                    <TextBlock Text="{TemplateBinding Content}" FontFamily="Segoe MDL2 Assets" FontSize="10" HorizontalAlignment="Center" VerticalAlignment="Center" RenderOptions.ClearTypeHint="Auto" TextOptions.TextRenderingMode="Aliased" TextOptions.TextFormattingMode="Display" />
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

<!--Minimize-->
<Style x:Key="MinimizeButton" TargetType="{x:Type Button}" BasedOn="{StaticResource TitleBarButton}">
    <Setter Property="Content" Value="&#xE949;" />
    <Setter Property="Background" Value="LimeGreen" />
</Style>

<!--Maximize-->
<Style x:Key="MaximizeButton" TargetType="{x:Type Button}" BasedOn="{StaticResource TitleBarButton}">
    <Setter Property="Content" Value="&#xE739;" />
    <Setter Property="Background" Value="Orange" />
</Style>

<!--Restore-->
<Style x:Key="RestoreButton" TargetType="{x:Type Button}" BasedOn="{StaticResource TitleBarButton}">
    <Setter Property="Content" Value="&#xE923;" />
    <Setter Property="Background" Value="Orange" />
    <Setter Property="Visibility" Value="Collapsed" />
</Style>

<!--Close-->
<Style x:Key="CloseButton" TargetType="{x:Type Button}" BasedOn="{StaticResource TitleBarButton}">
    <Setter Property="Content" Value="&#xE106;" />
    <Setter Property="Background" Value="Firebrick" />
</Style>

然后我從主檔案中呼叫它：

 <Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/UI/Styles/TitleBarButtonStyles.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>

在按鈕上：

<Button Style="{StaticResource MinimizeButton}"
                    Grid.Column="2" 
                    Click="MinimizeBtn_OnClick" />

<Button x:Name="MaximizeBtn" Grid.Column="3" 
                    Style="{StaticResource MaximizeButton}" 
                    Click="MaximizeBtn_OnClick" />
<Button x:Name="RestoreBtn" Grid.Column="3" 
                    Style="{StaticResource RestoreButton}" 
                    Click="RestoreBtn_OnClick" />

<Button Style="{StaticResource CloseButton}" 
                    Grid.Column="4" 
                    Click="CloseBtn_OnClick" />

但是在所有按鈕上我都會收到錯誤訊息：Ressource 'STYLE_X_KEY_NAME' is not found（STYLE_X_KEY_NAME 是我想要應用的樣式的相應 x:Key）

編輯
兩個檔案都在同一個程式集中。
我已經嘗試了 pack uri 方法：

<ResourceDictionary Source="pack://application:,,,/VRChat Bases Manager;component/UI/Styles/TitleBarButtonStyles.xaml" />

它仍然顯示相同的錯誤。

編輯2
這里的檔案夾結構如下：

主檔案：\UI\Windows\PrimaryWindow.xaml
樣式檔案：\UI\Styles\TitleBarButtonStyles.xaml

編輯 3
出于某種原因，我的檔案\UI\Styles\RoundDropDownStyle.xaml以相同的方式被呼叫。

這里的檔案：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="ComboboxTextBoxStyle" TargetType="{x:Type TextBox}">

好的，我發現了問題：這是檔案上的構建操作屬性。
它被設定為AdditionalFiles。正在作業的檔案將其設定為Page. 一旦我改變它，它就像一個魅力。

顯然這是 Visual Studio 2022 的一種奇怪行為？
當您通過它創建檔案時，Right Click -> Add... -> New Item... -> Resource Dictionary (WPF)它作業正常。
如果你去Right Click -> Add.. -> New From Template... -> Resource Dictionary，它的構建操作設定為AdditionalFiles不起作用。

編輯 我認為這New from Template...實際上是 ReSharper 添加的一個功能。

uj5u.com熱心網友回復：

你的路徑應該是，

<ResourceDictionary x:Name="TitleBarButtonStyles" Source="../Styles/TitleBarButtonStyles.xaml" />

至于您的pack uri 方法，您在 URI 中有空格。考慮處理 Uri 路徑中的空格
