使用带有 C# 的 SDK 从 ZKTEco 设备获取考勤日志

Question

我正在尝试将 ZKTEco U650-C 与我公司的系统集成以自动获取出勤日志，但我无法使用 C# 连接到设备。

我设法从他们的网站下载了 SDK，其中包括 ZKHID、ZKCamera DLL 文件和 SDK 包装器，因此我可以导入和使用它们的功能。

在 Visual Studio 中，我无法引用 ZKHID 和 ZKCamera DLL 文件，因为它们是非托管的。虽然，我能够引用 ZKBioModuleSDKWrapper，因为它使用 PInvoke。

使用TcpClient类连接设备、初始化、终止设备等操作成功。但是，使用其他操作如打开设备，获取设备配置等无法进行，因为我不知道如何获取设备句柄。

我是用错了一套SDK还是别的原因？任何帮助将不胜感激。

Answer 1

原来我用错了一套SDK。 ZKTEco 从他们的官方网站上删除了 SDK 下载链接，所以我不得不从私人服务器下载正确的 SDK。

我在 Visual Studio 中正常添加了 zkemkeeper.dll 引用，对代码进行了一些更改，并且我设法接收了考勤日志。

using zkemkeeper;

            PORT = 4370,
        }

        {
            Console.WriteLine("Connecting...");
            CZKEM objCZKEM = new CZKEM();
            if (objCZKEM.Connect_Net("192.168.1.11", (int)CONSTANTS.PORT))
            {
                objCZKEM.SetDeviceTime2(objCZKEM.MachineNumber, DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second);
                Console.WriteLine("Connection Successful!");
                Console.WriteLine("Obtaining attendance data...");
            }
            else
