Assembly.CodeBase：什么时候没有文件-URI？

发布于 2024-08-08 15:11:04 字数 333 浏览 3 评论 0 原文

Assembly.Location 给出了程序集的简单路径。不幸的是，当在影子环境（例如单元测试或 ASP.NET）中运行时，该值是空的。不过，Codebase 属性可用，并提供了可以替代使用的 URI。在什么情况下它不返回以 file:/// 开头的 URI？或者换句话说：在什么情况下这不起作用或将返回不可用的结果？

Assembly assembly = GetType().Assembly;    
Uri codeBaseUri = new Uri(assembly.CodeBase);
string path = codeBaseUri.LocalPath;

Assembly.Location gives a plain path to the assembly. Unfortunately this is empty when running in a shadowed environment, such as unit test or ASP.NET. Hovever, the Codebase property is available and provides a URI that can be used instead. In which cases it returns no URI starting with file:///? Or in other words: what are the cases in which this won't work or will return unusable results?

Assembly assembly = GetType().Assembly;    
Uri codeBaseUri = new Uri(assembly.CodeBase);
string path = codeBaseUri.LocalPath;

可以直接通过 HTTP 加载程序集，例如在 ClickOnce 部署中：

Assembly assembly = Assembly.LoadFrom("http://server/app.dll");
Uri codeBaseUri = new Uri(assembly.CodeBase);
Debug.Assert(codeBaseUri.Scheme == "http"); 
Debug.Assert(codeBaseUri.LocalPath == "");
Debug.Assert(assembly.Location == "");

It's possible to load assemblies directly over HTTP, such as in a ClickOnce deployment:

Assembly assembly = Assembly.LoadFrom("http://server/app.dll");
Uri codeBaseUri = new Uri(assembly.CodeBase);
Debug.Assert(codeBaseUri.Scheme == "http"); 
Debug.Assert(codeBaseUri.LocalPath == "");
Debug.Assert(assembly.Location == "");
