推荐答案

切勿在 Windows 系统目录中放置任何内容(除非您有非常、非常、非常好的理由在那里编写).

Never put anything in the Windows system directories (unless you have a very, very, very good reason to write there).

这是一个非常糟糕的做法(追溯到 Windows 3.x 时代和糟糕的开发人员技能，因为这些目录总是在搜索路径中)只会导致麻烦(即，如果另一个应用程序用它自己的没有检查).将 DLL 放在应用程序文件夹中.它将确保您的应用程序使用正确版本的 DLL.或者，如果您出于非常、非常、非常好的理由必须在其他地方编写它，请使用其中一种技术将目录添加到搜索路径或重定向 DLL 加载.

It's a very bad practice (dating back to Windows 3.x times and poor developers skills, because those dirs are always in the search path) just leading to troubles (i.e. if another application chnages your DLL with its own with little or no checks). Put the DLL in the application folder. It will ensure your application uses the correct version of the DLL. Or if you have to write it elsewhere for a very, very, very good reason use one of the techniques to add a directory to the search path or redirect DLL loading.

Windows 系统目录必须被视为操作系统私有目录.这类 Windows 还不够禁止的做法往往会使 Windows 成为一个缓慢且不稳定的系统.

Windows system directories must be regarded as operating system private ones. This kind of practices which Windows doesn't forbids enough are those that often makes Windows a slow and unstable system.

如果您的应用程序是 32 位的，则无论操作系统如何，您都需要 32 位的 DLL.

If you're application is 32 bit, you need the 32 bit DLL regarless of the operating system.
