在同一进程中加载​​dll的多个副本 [英] Load multiple copies of dll in same process

问题描述

我有一个由第三方生成的dll，它有某种内部数据结构，将其大小限制为X个元素。

基本上，它有一个Queue X为限制。

现在从我已知的DLL的每个进程，但是可以不止一次加载DLL？也许每个线程？在C＃中？或在C ++ / CLI？

我正在尝试加载本机c ++ dll。

解决方案

不幸的是，NT核心 DLL加载程序不会公开公共接口来跳过已经加载的DLL的池。因此，您只剩下几个选择：

• 复制，硬链接，符号链接和/


• 使用多个进程，并且每个进程加载一个DLL。


• 编写一个新的DLL加载器




• 确认DLL的供应商修复它（可能比编写DLL加载器更难）
  

  I have a dll produced by a third party that has some sort of internal datastructure that limits it's size to X elements.

  So basically, it has a Queue with X as the limit.

  Now from what I've known DLL's are per process, but is it possible to load a DLL more than once? Maybe per thread? In C#? or in C++/CLI?

  I'm trying to load a native c++ dll.

  解决方案

  Unfortunately, the NT core DLL loader routines don't expose a public interface to skip the pool of already-loaded DLLs. As such, you're left with just a few choices:

  • Copy, hardlink, symlink, and/or use reparse points to fool the loader into thinking you have multiple distinct DLLs.
  • Use multiple processes, and load one DLL per process.
  • Write a new DLL loader (very much not for the faint of heart!)
  • Convince the DLL's vendor to fix it (likely to be harder than writing a DLL loader :)
