Question

我试图在另一个WCF应用程序中使用Growl Alike WPF Notification。但是我在尝试运行它时遇到错误。我收到的错误是：

为System.Windows.Markup.StaticResourceHolder＆＃39;提供价值。抛出异常。

当我检查内部异常时，它会说

无法找到名为＆＃39; CloseButton＆＃39;的资源。资源名称区分大小写。

但是当我检查ButtonStyle.xaml时，它有资源CloseButton。

有没有人知道我错过了什么？

注意:: 当作为单个项目运行时，源代码可以正常工作

为了使用StaticResource，必须在尝试将其应用到同一视觉树中的元素之前定义样式。

您可以将资源字典添加到可视树中按钮上方的控件资源

<Window x:Class="StackOverflow.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <ResourceDictionary Source="ButtonStyle.xaml"/>
</Window.Resources>
<Grid>
    <Button Click="ButtonBase_OnClick" Style="{StaticResource CloseButton}">Click</Button>
</Grid>

或者您可以使用DynamicResource，它不要求样式在可视树中处于同一级别或更高级别。

<Button Click="ButtonBase_OnClick" Style="{DynamicResource CloseButton}">Click</Button>

XAML已缓存。打开* .xaml和* xaml.cs文件时，VS会锁定它。在Visual Studio中将其关闭，您可能会发现问题消失了。

Answer 3

示例

<Application.Resources>
    <ResourceDictionary Source="pack://application:,,,/WpfCustomControlLibrary1;component/UI/ButtonStyle.xaml" ></ResourceDictionary>
</Application.Resources>

也许是这样。使用Pack URI加载文件

https://docs.microsoft.com/en-us/dotnet/framework/wpf/app-development/pack-uris-in-wpf

找不到名为＆＃39; CloseButton＆＃39;的资源。资源名称区分大小写
