How to get Attendance log from ZKteco Biometric Machine using ZKteco SDK

ZKteco Attendance Device is widely used machine for bio-metric attendance and facial recognition attendance,

Here is the function how to get the device log from Machine using ZKteco SDK.

public DataTable LogTable()

            DT.Columns.Add("TTYPE");

            DT.Columns.Add("Description");

            return DT;

}
