中文怎么转换为bytes

例如“广东”  转化成byte[]={[-27, -71, -65, -28, -72, -100]} 

用一个现成的函数还是要稍微编个函数

回复讨论(解决方案)

var b = Encoding.UTF8.GetBytes("广东");Console.WriteLine(string.Join(",", b));

229,185,191,228,184,156

Byte 是无符号整型，如果你一定要负数的话就每项减 256

求直接的php代码，临时用，以后再仔细研究

$s = "广东";$s = iconv('gbk', 'utf-8', $s);$r = array_map('ord', str_split($s));print_r($r);

Array(    [0] => 229    [1] => 185    [2] => 191    [3] => 228    [4] => 184    [5] => 156)

或

$s = "广东";$s = iconv('gbk', 'utf-8', $s);$r = unpack('C*', $s);print_r($r);

Array(    [1] => 229    [2] => 185    [3] => 191    [4] => 228    [5] => 184    [6] => 156)

或

$s = "广东";$s = iconv('gbk', 'utf-8', $s);$r = unpack('C*', $s);print_r($r);

Array(    [1] => -27    [2] => -71    [3] => -65    [4] => -28    [5] => -72    [6] => -100)
