string_char把ascii数值转换成字符

string.byte(s [, i [, j]])

string.byte是用来把字符转换成ascii数字，s为目标字符串，i为索引开始位置(从1开始)，j为索引结束位置

string.char(...)

string.char是把ascii数值转换成字符

 

--默认为第1个返回a的ascii值

local r = string.byte('abcdefg') --97

 

--从索引2(b)到索引4(d)也就是分别返回bcd的ascii值

local r1,r2,r3 = string.byte('abcdefg',2,4) --98,99,100

 

--返回98所对应的字符

local r = string.char(98) --a

 

--返回98,,99,100对应的字符并连在一起返回

local r = string.char(98,99,100) --abc

 

local str=""

local tbl={}

for i=0,1000 do

if i<=255 then

local r = string.char(i)

str=str.."{"..i..","..r.."},"

else

local r= string.char((i-i%256)/256)

str=str.."{"..i..","..r..","

local r= string.char(i%256)

str=str..r.."},"

end

--table.insert(tbl,{i,r})

if i%10==0 then

str=str.."\n"

end

 

end

print(str)
