c# - Reading numbers from a text file to an array -
i want read numbers text file array. numbers in 1 line.
if use
x.read()
ascii code of first character,if use
x.readline()
, row, not numbers 1 one.
i want use cycle numbers 1 one.
it's simple, when ascii code can convert digit want, suppose read character (char
) file '0', '1', '2', ... or '9' , want int
value, simple convert char
int
, subtract integer value of '0' 48. this:
char ch = x.read(); int chintvalue = ((int)ch) - 48;
but modern programming languages have readint
, getinteger
method or in io
libraries provide.
