在代码 wpf 中访问资源字典 [英] accessing a resource dictionary in code wpf

问题描述

同一程序集中的同一行代码适用于一个测试夹具，但不适用于另一个.这是代码行:

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") };

我在另一个测试装置中得到的错误是 System.UriFormatException : Invalid URI: Invalid port specified.

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

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?

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

干杯，

正如我在这篇帖子中发现的那样，发生无效端口，因为包方案未注册，可以使用如下代码完成:

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);

我猜测，能够无误地加载带有包方案的字典的测试装置是因为 SUT 是那里的用户控件，并且在创建用户控件的实例时以某种方式加载资源.

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.

推荐答案

我使用的是 UriKind like

What I use is with UriKind like

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