Hi!

I want integrate fingerprint zkteco8500R with C# and save result in database. How possible the demo code write like this very simple?

The demo version I want use is below:

using System;
using System.Drawing;
using System.IO;
using System.Runtime.InteropServices;
using System.Threading;
using System.Windows.Forms;
using libzkfpcsharp;
using Sample;
using System.Drawing.Imaging;
