从错误信息思考一个问题：.NET Framework 与 COM/COM+ 到底有多深入的关联呢？
今天 针对2个程序文件， 用csc压了一个multi-file Assembly，发现了一个问题：
(1) SumNumber.cs，编译为 SumNumber.netmodule
| csc /target:module /out:bin\Debug\SumNumber.netmodule SumNumber.cs |
(2) Program.cs，编译为 MyConsole.exe，作为程序执行文件
| csc /target:exe /addmodule:bin\Debug\SumNumber.netmodule /out:bin\Debug\MyConsole.exe Progarm.cs |
这样执行是没有问题的！
然后我把SumNumber.netmodule删除掉，再次执行MyConsole.exe，出现了下面的错误：
| 未处理的异常: System.IO.FileNotFoundException: 未能加载文件或程序集“SumNumberM odule.netmodule”或它的某一个依赖项。系统找不到指定的文件。 文件名:“SumNumberModule.netmodule” ---> System.IO.FileNotFoundException: 系统 找不到指定的文件。 (异常来自 HRESULT:0x80070002) 在 MySolution.Program.Main(String[] args) |
眼瞅见 FileNotFoundException 倒没有什么，可是看到HRESULT就有点让我迷惑了：难道这里引发异常的根源是一个COM对象产生的？
问题来了：.NET Framework 与 COM/COM+ 到底有多深入的关联呢？
先做个标记，这几天研究一下...
