推荐答案

FKAttend.dll不是系统DLL，它是指纹识别系统的一部分（并且可能是系统制造商专有的）。

因此，它不太可能处于显而易见的地方系统将搜索：首先找到它，将其复制到您的项目文件夹并将其添加到您的项目，以便它最终在您的BIN文件夹中。



那个方式，系统有更好的机会找到它！ DLL搜索的规则如下：动态链接库搜索顺序（Windows） [ ^ ]

<如果这不起作用，请检查您的应用程序设置：如果DLL是32位文件而您的应用程序是64（反之亦然），则可能会导致类似问题。

FKAttend.dll is not a system DLL, it is part of a fingerprint recognition system (and is presumably proprietary to the manufacturer of the system).
As a result, it isn't likely to be in an "obvious place" that the system will search: Start by locating it, copying it to your project folder and adding it to your project so it ends up in your BIN folders.

That way, the system has a better chance of finding it! The rules for DLL searching are here: Dynamic-Link Library Search Order (Windows)[^]

If that doesn't work, check your app settings: if the DLL is a 32 bit file and your app is 64 (or vice versa) it could cause a similar problem.
