VS C# 中的依赖地狱，找不到依赖 [英] Dependency hell in VS C#, cannot find dependencies
问题描述
我创建了一个图表 C# 库(我们称之为 chartlibrary)，它本身依赖于多个第三方 dll 文件.
I created a chart C# library (let's call it chartlibrary) which itself has dependencies on multiple third-party dll files.
在另一个可执行项目(我们称之为 chartuser)中，我引用了 chartlibrary 项目(两个项目位于 Visual Studio 中的同一个解决方案中).
In another executable project (let's call it chartuser), I reference the chartlibrary project (both projects sit within the same solution in Visual Studio).
编译后，可以看到chartlibrary引用的所有第三方dll文件也都包含在chartuser的bin/Debug文件夹中.但是，我收到一个运行时错误，这基本上表明 chartlibrary 中的某些引用无法解析.然后我试图通过
Upon compilation, I can see that all the third-party dll files that chartlibrary references are also contained in the bin/Debug folder of chartuser. However, I get a runtime error which basically points to the fact that some of the references in chartlibrary cannot be resolved. I then tried to get a better idea via
AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;
和
private static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
var assemblyFileName = args.Name.Substring(0, args.Name.IndexOf(",")) + ".dll";
var assemblyPathFileName = _currentPluginPath + @"" + assemblyFileName;
if (File.Exists(assemblyPathFileName))
{
return Assembly.Load(File.ReadAllBytes(assemblyPathFileName));
}
return null;
}
问题是RequestingAssembly 为空，Name 非常神秘.
Problem is that the RequestingAssembly is null and Name is very cryptic.
即使所有 dll 都在可执行项目的 bin/Debug 文件夹中，但找不到引用 dll 并且无法解析程序集，我做错了什么?
What am I doing wrong that the reference dlls cannot be found and assemblies cannot be resolved even though all the dlls are in the bin/Debug folder of the executable project?
推荐答案
修复:针对与混淆引擎相关的第三方库的修复解决了该问题.
Fix: A fix for the third party library related to their obfuscation engine solved the issue.
<小时>
.NET 依赖项:也许略过这个旧答案:如何确定 .NET 应用程序的依赖项? - 并检查任何清单文件?
.NET Dependencies: Maybe skim this old answer: How do I determine the dependencies of a .NET application? - and go through any manifest files?
调试:Microsoft 程序集绑定日志查看器 可以显示运行时发生的情况.通过 Visual Studio 的开发人员命令提示符 启动它(只需搜索开发人员命令"，输入 FUSLOGVW.exe" 并按 Enter).也可以略读一下:如何运行时定位程序集.
Debugging: The Microsoft Assembly Binding Log Viewer can show you what's going on at runtime. Launch it via a Developer Command Prompt for Visual Studio (just search for "developer command", type in "FUSLOGVW.exe" and press Enter). Also maybe have a skim: How the Runtime Locates Assemblies.
我不太熟悉它们的用法，但还有一些其他工具(大多数还有依赖项之外的其他用途):
I am not familiar with their use that much, but there are some further tools (most have further uses beyond dependencies):
- ILSpy - I believe it is open source.
- AsmSpy - never tried it.
- NDepend - commercial.
应用启动清单:
运行时:如果问题发生在另一台计算机上，则首先出现在清单上的明显运行时:.Net、.Net Core、Java、Silverlight、Direct X、VC++ Runtime、MS-XML (legacy)、Crystal Reports、Microsoft Report Viewer、SQL Server/Database Runtimes 等...加上任何涉及 COM 注册的内容，以及您所指的任何第三方框架组件(COM、COM 互操作、GAC、程序集等).
Runtimes: If the issue happens on another computer, the obvious runtimes that are first on the check-list: .Net, .Net Core, Java, Silverlight, Direct X, VC++ Runtime, MS-XML (legacy), Crystal Reports, Microsoft Report Viewer, SQL Server / Database Runtimes, etc... Plus anything involving COM-registration and obviously any third party framework components that you refer to (COM, COM Interop, GAC, Assemblies, etc...).
