如何在C#项目中使用ZK4500指纹扫描仪SDK [英] How to use ZK4500 Fingerprint Scanner SDK in C# Project

问题描述

我正在用C#开发一个项目，我想使用其指纹来登录/验证用户.

I am developing a project in C#, for which I want to login/authenticate a user using their fingerprint.

我购买了ZK4500指纹扫描仪，并从 http://www.zkteco获得了SDK. com/product/ZK4500_238.html .该SDK使用C ++.

I bought a ZK4500 Fingerprint scanner and got its SDK from http://www.zkteco.com/product/ZK4500_238.html. The SDK is in C++.

那么我如何将该SDK与C#项目集成在一起以执行所需的功能?

So How can I integrate this SDK with my C# project to perform the desired functionality?

推荐答案

您需要添加对ZKFPEngXControl的引用，该引用将出现在COM类型库下.之后，您可以使用ZKFPEngX类执行所需的任何操作.

You need to add reference to ZKFPEngXControl that will appear under COM Type Libraries. After that you can use the ZKFPEngX Class to do whatever you require.

using ZKFPEngXControl;

然后

ZKFPEngX fp = new ZKFPEngX();
fp.SensorIndex = 0;
fp.InitEngine(); // Do validation as well as it returns an integer (0 for success, else error code 1-3)
//subscribe to event for getting when user places his/her finger
fp.OnImageReceived += new IZKFPEngXEvents_OnImageReceivedEventHandler(fp_OnImageReceived);

您可以编写自己的方法fp_OnImageReceived来处理事件.例如，您可以在该方法中编写该代码；

You can write your own method fp_OnImageReceived to handle the event. for example you can write this in that method;

object imgdata = new object();
bool b = fp.GetFingerImage(ref imgdata);

其中imgdata是字节数组.您还可以在ZKFPEngX中使用其他方法来实现目标.请记住在表单关闭时关闭引擎.

Where imgdata is an array of bytes.You can also use other methods in ZKFPEngX, to achieve your goals. Remember to close the engine when form closes.

fp.EndEngine();
