问题描述
我需要从一个字节数组得到具体的字节。我知道我要的第一个字节的内容,我需要X字节后。
例如,我有
字节[] readbuffer {0,1,2,将0x55,3,4,5,6};
字节[] =结果新的字节[30];
和我需要将0x55
后出现的3个字节 字节结果== {ox55aa,3,4,5}
我使用的是:
Array.copy(readbuffer,将0x55需要的指数,结果,0,3);
我需要找到的将0x55指数
PS:将0x55
是数组中的一个偶然的位置。
PS2:我忘了提及此之前,我在.NET微架构正在工作。
(对不起了非code说明,我是一个非常新手编程...英文)
感谢您提前
X2
字节[] =结果新的字节[16];
INT指数= Array.IndexOf(readBuffer,(字节)将0x55);
Array.Copy(readBuffer,索引,结果,0,16);
感谢大家。
这是我的code现在。它的工作如我所料:)
I need to get specific bytes from a byte array. I know the content of the first byte I want and I need x bytes after that.
For example, I have
byte [] readbuffer { 0, 1, 2, 0x55, 3, 4, 5, 6};
byte [] results = new byte[30];
and I need the 3 bytes that appear after "0x55"
byte results == {ox55aa, 3, 4, 5}
I'm using:
Array.copy(readbuffer, "need the index of 0x55" ,results, 0, 3);
I need to find the index of 0x55
PS: 0x55
is in an aleatory position in the array.PS2: I forgot to mention before that I'm working in .Net Micro Framework.
(I'm sorry for the non code description, I'm a very newbie to programming... and english)
thank you in advance
[edited]x2
byte[] results = new byte[16];
int index = Array.IndexOf(readBuffer, (byte)0x55);
Array.Copy(readBuffer, index, results, 0, 16);
Thank you all.
This is my code now. it's working as I expect :)
