Question

c# regex replace

Answer 1

+1 A:

type="xxx\.yyy\.zzz, xxx\.yyy, Version=\d+\.\d+\.\d+\.\d+, Culture=neutral, PublicKeyToken=null"

\d stands for a digit; \d+ matches one or more digits.
. is a special character and needs to be escaped as \.

As a c# regex string, it'd look like:

pattern = "type=\"xxx\\.yyy\\.zzz, xxx\\.yyy, Version=\\d+\\.\\d+\\.\\d+\\.\\d+, Culture=neutral, PublicKeyToken=null\"";

Hhm, what if there is a extra space or if version is only specified to x.x.x or if culture is not neutral. I know it is not your Regex there is faulty, but rather the question which lacks some information.

@lasseespeholt OP said _rest of the string does not change_ and I relied on that.

Amarghosh 2010-07-09 13:47:18

Yes, I know :) Again, I know your regex is not faulty. But will a extra space qualify for "a change"? <- question for Bala R

lasseespeholt 2010-07-09 13:50:15

@lasseespeholt there won't be an extra space.

Bala R 2010-07-09 13:58:49

@Bala and does this regex work for you?

Amarghosh 2010-07-09 14:02:02

I'm now struggling with the Unrecognized escape sequence error. Will update once I get it to work.

Bala R 2010-07-09 14:08:55

oops - make all those \ to \\ - one for java, one for regex. See my update @Bala

Amarghosh 2010-07-09 14:11:14

I don't understand. why do I need the java regex string ?in c# i tried replaciont \ with \\; that compiles but does not work.

Bala R 2010-07-09 14:16:00

@Bala C# or java, you need to escape backslashes in a string.

Amarghosh 2010-07-09 14:19:31

ok that worked. Thanks.
