                StringBuilder strCatalog = new StringBuilder();
                strCatalog.Append('\0', 64);
           }
}

調(diào)用dll文件：

 public static extern int RDR_LoadReaderDrivers(string drvpath);

        [DllImport("rfidlib_reader.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall)

備注：C:\\Drivers這個文件夾存在，卻提示找不到模塊，原因是bin目錄下缺少這個dll文件，把文件rfidlib_reader.dll拷貝到bin目錄下搞定。
