问题描述

请任何人帮我一个在我的c＃应用程序中添加FTRAPI.dll和ftrScanAPI.dll引用文件的方法。我尝试后一直收到这个错误;



''对'C：\ Users \EME \Desktop \ WorkedEx \ FTRAPI.dll的引用'无法添加。请确保该文件是可访问的，并且它是一个vaild程序集或COM组件。''



我需要这些文件来帮助我从中捕获指纹图像futronic fs80扫描仪。

使用这些文件的任何其他替代方案也是受欢迎的。非常感谢。

Please can any one help me with a way to add FTRAPI.dll and ftrScanAPI.dll reference files in my c# application. I keep getting this ERROR once i try;

'' A reference to 'C:\Users\EME\Desktop\WorkedEx\FTRAPI.dll' could not be added. Please make sure that the file is accessible, and that it is a vaild assembly or COM component.''

I need the files to help me capture fingerprint images from a futronic fs80 scanner.
Any other alternatives to using the files would be welcome too. Thanks a lot.

这些库可能不是COM DLL，因此您无法以这种方式使用它们。你应该回到你从那里得到它们的地方或那个人。并且在那里问。

The chances are that these libraries are not COM DLLs so you cannot use them in this way. You should go back to the place or person you got them from and ask there.

FTRAPI.dll不适用于Frigerprint扫描

它用于验证< br $>




并且它不是COM组件所以你需要使用DllImport函数来导入dll函数

FTRAPI.dll is not for the Frigerprint Scanning
it's for the verification


and it's not the COM Component so you need to use "DllImport" function to import the dll function
