Hi,
Is there a class that can handle splitting of a string on a comma such
that the commas in quotes are ignored?
I know we can use Text::ParseWord s directive in perl to do this, but I
am new to C#.Net and couldn't find anything similar.
For example
string str = "one field, two field, \"field val one, field val two,
field val three\", three field" ;
Then I should get the following in a str_arr
str_arr[0] = "one field"
str_arr[1] = "two filed"
str_arr[2] = "field val one, field val two, field val three"
str_arr[3] = "three field"
Thanks in advance,
Ashoo. 19 1729
string[] str_arr = str.Split(",");
string [] str_arr = str.Split(',');
does not work. I had tried it. It gives me
str_arr[0] = "one field"
str_arr[1] = "two filed"
str_arr[2] = "\"field val one"
str_arr[3] = "field val two"
str_arr[4] = "field val three\""
str_arr[5] = "three field"
Instead of
str_arr[0] = "one field"
str_arr[1] = "two filed"
str_arr[2] = "field val one, field val two, field val three"
str_arr[3] = "three field"
look at the str_arr[2] value.
Thanks,
Ashoo

hi,
you can use Regular Expression which can give u such results. here is
one regular expression which will fetch you your desired result. i
assumed that you are using VS2003.
(?:(?<Vals>.*?) ,)+"(?<Vals>.*? )"(?:,(?<Vals>. *?))+$
the ouput of your given example will be like this :
SubMatch: [Vals]
1:one field
2:two field
3:field val one, field val two,field val three
4:three field
try it out
At this time using split more than once seems to be the only option. I
cant recollect any other function that can help you do this quicker.
how do you use that function in perl? put some code and may be that can
ring the bell for some csharpers.
thanks

This is how you cld do it in perl
#!/usr/bin/perl
use Text::ParseWord s;
$line = "one field, two field, \"field val one, field val two,field val
three\", three field" ;
my @line = &parse_line('\, ', 0, $line);
for (int i=0; i<$#line; i++)
print $line[i];
Thanks,
Ashoo

Have you tried using regular expressions, instead of the Split()?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
