我有一个名为Atelis.Base.Wpf.Resources
. 它是一个包含资源字典的 DLL。
在这个程序集中,我定义了一个SharedResourceDictionary
:
namespace Atelis.Base.Wpf.Resources
{
/// <summary>
/// The shared resource dictionary is a specialized resource dictionary
/// that loads it content only once. If a second instance with the same source
/// is created, it only merges the resources from the cache.
/// </summary>
public class SharedResourceDictionary : ResourceDictionary
{
/// <summary>
/// Internal cache of loaded dictionaries
/// </summary>
public static Dictionary<Uri, ResourceDictionary> _sharedDictionaries =
new Dictionary<Uri, ResourceDictionary>();
/// <summary>
/// Local member of the source uri
/// </summary>
private Uri _sourceUri;
/// <summary>
/// Gets or sets the uniform resource identifier (URI) to load resources from.
/// </summary>
public new Uri Source
{
get { return _sourceUri; }
set
{
try
{
_sourceUri = new Uri(value.OriginalString);
}
catch
{
// do nothing?
}
if (!_sharedDictionaries.ContainsKey(value))
{
// If the dictionary is not yet loaded, load it by setting
// the source of the base class
base.Source = value;
// add it to the cache
_sharedDictionaries.Add(value, this);
}
else
{
// If the dictionary is already loaded, get it from the cache
MergedDictionaries.Add(_sharedDictionaries[value]);
}
}
}
}
}
然后我有许多资源字典文件,如下所示:
样式.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<!-- styles are defined here -->
</ResourceDictionary>
颜色.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
>
<Color x:Key="Color1">#FF000000</Color>
<!-- ... many more colors and brushes are defined here -->
</ResourceDictionary>
按钮.xml
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Atelis.Base.Wpf.Resources"
>
<ResourceDictionary.MergedDictionaries>
<local:SharedResourceDictionary Source="pack://application:,,,/Atelis.Base.Wpf.Resources;component/Colors.xaml"/>
<local:SharedResourceDictionary Source="pack://application:,,,/Atelis.Base.Wpf.Resources;component/Styles.xaml"/>
</ResourceDictionary.MergedDictionaries>
<!-- a ton of button styles are defined here -->
</ResourceDictionary>
数据模板.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:base="clr-namespace:Atelis.Base.Client;assembly=Atelis.Base.Wpf"
xmlns:local="clr-namespace:Atelis.Base.Wpf.Resources"
>
<ResourceDictionary.MergedDictionaries>
<local:SharedResourceDictionary Source="pack://application:,,,/Atelis.Base.Wpf.Resources;component/Buttons.xaml"/>
<local:SharedResourceDictionary Source="pack://application:,,,/Atelis.Base.Wpf.Resources;component/Colors.xaml"/>
</ResourceDictionary.MergedDictionaries>
<!-- a ton of templates are defined here -->
</ResourceDictionary>
一切都很好,直到我到达DataTemplates.xaml
。这Buttons.xaml
SharedResourceDictionary
给了我一个内联警告“无法创建未知类型'{clr-namespace:Atelis.Base.Wpf.Resources}SharedResourceDictionary'。” 当我尝试定义staticresource
样式时,我收到另一个 xaml 警告“资源 'ButtonStyle2' 无法解析。”
我认为重要的是要注意SharedResourceDictionary
源 URI 不包含的其他声明SharedResourceDictionaries
没有这个问题(我可以在没有任何警告的情况下将颜色和样式添加到字典声明中,并且资源在设置时解析)。
该应用程序运行良好,但我似乎无法让 Visual Studio 解决此资源并删除警告。这是一个小小的不便,但我很想知道为什么会这样。
