我试图通过C#代码捕获指纹。我已经引用了Windows版本2.3.3.0的secugen FDx Pro SDK,并安装了驱动程序。虽然我看不到其他dll文件中的sgfplib.dll。
当我运行尝试初始化使用sgfplib.dll的SGFingerPrintManager的代码时,它抱怨“找不到sgfplib.dll”,我已经在该平台上阅读了先前的建议,但没有解决问题。
请先感谢您提出任何解决此问题的建议。
谢谢。
a)我已经下载了用于Windows的FDx Pro SDK和secugen驱动程序版本6.7(64)。 b)另外,我尝试将sgfplid.dll复制到项目的bin文件夹中,但问题仍然存在。

实际结果:预期结果是能够捕捉指尖
错误度量:标题[FDx SDK Pro.NET]。正文[找不到sgfplib.dll]
答案 0 :(得分:0)
我已经通过获取用于Windows的FDx SDK Pro的可执行文件并进行安装来解决了该问题。
问题是由FDx SDK Pro引起的。对于Windows无法看到sgfplib.dll文件,该文件在安装过程中自动安装在Windows / System32和Windows / sysWOW64目录中。
感谢所有人。
