Hello, I have an file that I am reading and it has some goffy characters in
it and I want to use a regular expression to clean up those characters. I am
not sure how to construct a regular expression which find these characters
and replace them with spaces. I am guessing that a regular expression which
would find the "good" values would look something like this..
Regex expr = new Regex (@"\w()\.,!@#$%<>" - but I am looking for anything
which is the oposite of that, as if I find something which is not in this
list, I want to replace it with spaces. (i.e expr.Replace("MyText|", " ");
)
I was thinking of using the following, but how to I tell it all the other
characters it should exclude from the match? Is there a "NOT" instruction?
Regex regexpr = new Regex (@"\W");
Hopefully this make sense...
Thanks in advance for your assistance!!! 2 2409

[abc] matches a or b or c
[^abc] anything but a, b or c

Yes!
Just as [abcd] matches a single character which is one of a b c or d,
[^abcd] matches a single character which is NOT one of a b c or d. So
given that
\w()\.,!@#$%<>
are your 'good' characters,
[^\w()\.,!@#$%<>]
will match any 'bad' character.
