我最近升级C＃窗口服务作为一个64位的.NET进程中运行。通常情况下，这将是微不足道的，但该系统使用了一个32位的DLL用C ++编写的。这不是一个选项，这个DLL转换为64位，所以我包的DLL在一个单独的32位.NET程序，并通过远程露出了.NET接口。

I recently upgraded a c# windows service to run as a 64 bit .net process. Normally, this would be trivial, but the system makes use of a 32-bit DLL written in C++. It is not an option to convert this DLL to 64 bit, so I wrapped the DLL in a separate 32 bit .net process and exposed a .net interface via remoting.

这是一个相当可靠的解决方案，但我想preFER运行系统作为一个单一的过程。有什么办法，我可以载入我的32位的DLL到64位进程和（可能通过某种的thunk层）直接访问它？

This is quite a reliable solution, but I would prefer to run the system as a single process. Is there any way I can load my 32 bit DLL into a 64 bit process and access it directly (perhaps through some sort of thunking layer)?

推荐答案

没有，你不能。
