在代码wpf中访问资源字典

发布于 2024-09-15 08:24:06 字数 768 浏览 7 评论 0原文

同一程序集中的同一行代码适用于一个测试夹具，但不适用于另一测试夹具。这是代码行：

var dic = new ResourceDictionary { Source = new Uri("pack://application:,,,/MyApp.Wpf;component/ImageResources.xaml") };

我在另一个测试装置中遇到的错误是 System.UriFormatException ：无效的 URI：指定的端口无效。

uri 字符串也适用于 xaml。有没有更好的方法在代码中加载资源字典？

干杯，

正如我在这篇文章中发现的< /a>，发生了无效端口，因为包方案未注册，这可以使用如下代码来完成：

if (!UriParser.IsKnownScheme("pack"))
     UriParser.Register(new GenericUriParser(GenericUriParserOptions.GenericAuthority), "pack", -1);

我猜测能够使用包方案加载字典且没有错误的测试装置是因为SUT 是其中的一个用户控件，并且在创建用户控件的实例时以某种方式加载资源。

原文

The same line of code in the same assembly works for one test fixture but not another. Here is the line of code:

var dic = new ResourceDictionary { Source = new Uri("pack://application:,,,/MyApp.Wpf;component/ImageResources.xaml") };

The error I get in the other test fixture is System.UriFormatException : Invalid URI: Invalid port specified.

The uri string also works in xaml. Is there a better way to load a resource dictionary in code?

Cheers,
Berryl

=== UPDATE ===

As I found in this posting, an Invalid port was occurring because the pack scheme wasn't registered, which can be done with code like so:

if (!UriParser.IsKnownScheme("pack"))
     UriParser.Register(new GenericUriParser(GenericUriParserOptions.GenericAuthority), "pack", -1);

I am guessing that the test fixture that was able to load the dictionary with the pack scheme without error is because the SUT is a user control there, and is somehow loading resources when an instance of the user control is created.

我使用的是 UriKind，比如

var resource = new ResourceDictionary
{
    Source = new Uri("/myAssemblyName;component/Themes/generic.xaml",
                     UriKind.RelativeOrAbsolute)
};

HTH

What I use is with UriKind like

var resource = new ResourceDictionary
{
    Source = new Uri("/myAssemblyName;component/Themes/generic.xaml",
                     UriKind.RelativeOrAbsolute)
};

@Prince Ashitaka 答案告诉您如何更正您的 URI

但是，访问 ResourceDictionary 的首选方法是在 XAML 中将其添加为合并字典

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="ImageResources.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

，然后您可以使用 TryFindResource(string Key)TryFindResource(string Key) 通过代码访问它code> 来自任何代码隐藏文件

@Prince Ashitaka answer tells you how to correct your URI

However the preferred way of accessing a ResourceDictionary is that in XAML you add it on as a merged dictionary

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="ImageResources.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

then you can access it via code using the TryFindResource(string Key) from any code behind file
