为什么我的 .NET 应用程序尝试加载不相关的 DLL 文件？（调试输出中第一次出现 System.BadImageFormatException）

在调试时，我注意到这里的这个 C# 应用程序出现以下情况：

它似乎尝试加载恰好与可执行文件驻留在同一目录中的所有 DLL 文件。（即使是那些与此项目/解决方案中的任何内容完全无关的应用程序。）

该应用程序正在加载并正常工作，但是我发现调试输出很奇怪：（路径被剪断）

...
A first chance exception of type 'System.BadImageFormatException' occurred in mscorlib.dll
'my_test.exe': Loaded '....\release\mfc42u.dll', Symbols loaded (source information stripped).
'my_test.exe': Unloaded '....\release\mfc42u.dll'
A first chance exception of type 'System.BadImageFormatException' occurred in mscorlib.dll
'my_test.exe': Loaded '....\release\mpiwin32.dll', Binary was not built with debug information.
'my_test.exe': Unloaded '....\release\mpiwin32.dll'
A first chance exception of type 'System.BadImageFormatException' occurred in mscorlib.dll
...

上面的两个 DLL 与 C# 项目或它引用的任何内容。为什么可执行文件（或 VS 调试器？）尝试加载这些 DLL？

While debugging, I notice the following with this C# app I have here:

It appears to try to load all DLL files that happen to reside in the same directory as the executable. (Even ones that are completely unrelated to anything in this project/solution.)

The app is loading and working fine, however I find the debug output weird: (paths snipped)

The two DLLs above have absolutely nothing to do with the C# project or anything it references. Why is the executable (or the VS debugger?) trying to load these DLLs?

看来这个应用程序毕竟正在主动加载这些 DLL！

我在一个我不熟悉的组件中找到了这段代码：

...
foreach (FileInfo file in dirInfo.GetFiles())
{
...
  try
  {
    Assembly ass = Assembly.LoadFrom(file.FullName);
...
  catch (Exception)
  {
    // Ignore all errors caught due to the .NET framework not being able to load an assembly.
    // Not all qualifying files in the specified directories really are valid .NET assemblies.
  }
...

0xA3 关于捕获第一次机会异常的评论让我走上了正轨！

Seems this app is actively loading these DLLs after all!

This code I found in a component I was not familiar with:

...
foreach (FileInfo file in dirInfo.GetFiles())
{
...
  try
  {
    Assembly ass = Assembly.LoadFrom(file.FullName);
...
  catch (Exception)
  {
    // Ignore all errors caught due to the .NET framework not being able to load an assembly.
    // Not all qualifying files in the specified directories really are valid .NET assemblies.
  }
...

0xA3's comment about catching the 1st chance exception got me on the right track!
