一、代码

 public class CyberWin_hoteldoor_prousbv10_2024
    {
        [DllImport("024.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall, EntryPoint = "GetDLLVersion")]
        public static extern int GetDLLVersion(StringBuilder sDllVer);


        [DllImport("24.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall, EntryPoint = "initializeUSB")]
        public static extern int initializeUSB(int d12);


        [DllImport(".dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall, EntryPoint = "CloseUSB")]
        public static extern void CloseUSB();

	[DllImport(".dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall, EntryPoint = "CardErase")]
        public static extern int CardErase(int d12, int dlsCoID, StringBuilder CardNo);
   }
