背景:byte.length只能获取到初始化的byte数组长度,而不是实际使用的长度,因此想要获取到实际的使用长度只能靠其他方法实现. 方法一: public class ByteActualLength { public static int returnActualLength(byte[] data) { int i = 0; for (; i < data.length; i++) { if (data[i] == '\0')
public byte[] getBytes(Charset charset) Encodes this String into a sequence of bytes using the given charset, storing the result into a new byte array. This method always replaces malformed-input and unmappable-character sequences with this charset'

一个工作任务涉及到c#与c++系统间的udp通信,处理了蛮长时间没有完成任务,但是期间接触到不少小知识点.本人是初接触c#,c++语言没有接触过.可能写的东西都很小儿科,暂且记录下来当工作日记把. 先解决本文的主题:c#中结构体与byte[]间相互转换,以便帮助查阅到的人解决一下问题.在工作任务过程中,学习到了c#中结构体与byte[]间相互转换.做的代码实验如下: using System; using System.Collections.Generic; using System.Linq
byte数组和short数组转换 public short bytesToShort(byte[] bytes) { return ByteBuffer.wrap(bytes).order(ByteOrder.LITTLE_ENDIAN).getShort(); } public byte[] shortToBytes(short value) { ).order(ByteOrder.LITTLE_ENDIAN).putShort(value).array(); } public short[]
