C# 如何从包含其程序集和任何程序集路径的Uri加载资源?
我想仅使用其uri从任何程序集(同一应用程序)加载任何资源。两个程序集都是同一应用程序的一部分 因为我希望能够从任何程序集加载,所以我不能使用未在常规Dll中定义的“应用程序”或“应用程序” 我认为部分或答案是使用:C# 如何从包含其程序集和任何程序集路径的Uri加载资源?,c#,file,resources,uri,.net-assembly,C#,File,Resources,Uri,.net Assembly,我想仅使用其uri从任何程序集(同一应用程序)加载任何资源。两个程序集都是同一应用程序的一部分 因为我希望能够从任何程序集加载,所以我不能使用未在常规Dll中定义的“应用程序”或“应用程序” 我认为部分或答案是使用:System.Reflection.Assembly.GetCallingAssembly().GetManifestResourceStream(路径) 但是我找不到如何正确地从uri中查找/提取/解析程序集 注: 资源实际上被定义为“资源” 资源不是WPF资源字典的PAR。 资

但是我找不到如何正确地从uri中查找/提取/解析程序集
注:
- 资源实际上被定义为“资源”
- 资源不是WPF资源字典的PAR。
- 资源实际上是一个XML文件,但可以是任何内容
到目前为止(大约3小时后),在使用reflector之后,似乎使用静态System.Windows.Application.GetResourceStream(uri).Stream具有资源缓存等优点。这是不好的,因为它连接到WPF(System.windows)。我正在寻找更好的方法(不依赖于任何特定的UI框架)来完成这项工作。我使用下面定义的“LoadResourceFromUri”函数解决了我的问题。我在上完成并发布了一个项目,该项目使用一个工具加载任何模块(dll)并显示其资源。还可以获取有关uri的信息
在将byteArray转换为stream时,我使用了大约4的偏移量,因为否则(没有偏移量),它就不能按预期工作
