If  you're wanting to capture the full code from the given string, this might work for you:
\d\d([A-Z\d]*-)+[A-Z\d]*

I've assumed "anychars" includes numbers and capital letters at this stage.

Don't know about the "Page 1 of 27" part.

For the rest, you can use
@"\d{2}([a-zA-Z0-9]*?-)+[a-zA-Z0-9]*$"

LE: 40 seconds late :)

HTH,

@"\d{2}([a-zA-Z0-9]*?-)+[a-zA-Z0-9]*$"

this is not capturing the page part. I want the whole thing to be capture starting from page
it can be
 Page * of *  280DABC2BB-5ECDC9A0-144B9203297-17F85

It can be refined:
"Page [1-9][0-9]* of [1-9][0-9]* [1-9][0-9]([A-Za-z0-9]*-)+[A-Za-z0-9]*"

Open in new window

The page number (or number of pages) should not start with 0. Same for the serial number.
You can remove the "a-z" if you only have capital letters.

The code is matching both strings thats wrong, it should match the first value only

 string fieldValue="280DABC2BB-5ECDC9A0-144B9203297-17F85";
 string fieldValue = "102-33-3639";

I want the whole 3 hyphen to be recognized by the pattern or it will match something else

That was not in the constraints :) This will match only if there are 4 groups of characters, separated by "-"

"Page [1-9][0-9]* of [1-9][0-9]* [1-9][0-9]([A-Za-z0-9]*-){3}[A-Za-z0-9]*"
