Byte data type is a simple data type to store a single, 8-bit character as a value in the range 0 to 255 in Microsoft Dynamics NAV.
//String hexString = "48656c6c6f"; // 示例十六进制字符串 "Hello" byte[] byteArray = DatatypeConverter.parseHexBinary(hexString); return byteArray; } **//** * 十六进制字符串转字节数组 | 方法2 * @note 局限性 : byte 的取值范围 : [-128, 127] ...

Strings contain Unicode characters. Their literals are written in single or double quotes : 'python', "data". Bytes and bytearray objects contain single bytes – the former is immutable while the latter is a mutable sequence. Bytes objects can be constructed the constructor, bytes(), and from...

create two sockets on the client side, also known as the sender side, to send OOB data and normal data. On the server side, also known as the receiver side, you use two sockets to process the data in two threads. One thread is for OOB data. The other...
