asp.net find match value WITHOUT search string for "whatever: "

I have a string that looks like this:

'ACCEPT - The transaction succeeded. Merchant Reference
Code:OrderId
Request ID: 1865550982350176174087 Authorized Amount: 10.00
Authorization Code: 123456 Authorization Time:
2007-08-09T14:18:18Z


I need to pull out that string after "Request ID:
"


which in this case should be :


1865550982350176174087


This returns the full string with the search string:


Dim regexp As Regex = New Regex("Request ID:
(w+)",
RegexOptions.IgnoreCase)
Dim TransId As String = regexp.Match(CCOut).ToString
StatusLabel.Text = TransId.ToString


and this returns nothing:


Dim pattern As String = "Request ID: (w+)" &
Regex.Escape("Request
ID: ")
Dim match As Match = Regex.Match(CCOut, pattern)
StatusLabel.Text = match.Value.ToString


Thank you for any help or information!

It's returning "Request ID: " too, I only want the
string that
follows. I have a simple workaround of removing that from
the match.
But is there a better way?

Hi jobs,

Llyod has the right expression. You may use braces to group
your
match. Try this.

Pattern:
Request ID:s*([0-9]+)

Match:
Request ID: 1865550982350176174087
$1:
1865550982350176174087

$1 is what you need. I am not sure where you are using this
but $1 or
1 would be 'group' your submatches.

Thanks!
Syd

Can't be done.
[0-9]+ would return anything containing digits.

1865550982350176174087
10
123456
2007
08
09
14
18
18
would all be matched if we used that.

The point is that "Request ID: " has to be used to
identify the
correct match.

I am not familiar with ASP.NET regex engine. But I would
recommend
looking up grouping of expressions in ASP.NET help.

Thanks!
Syd

Hi jobs,

Spoke too soon.

Here's the expression you should use:
(?<=Request ID:s*)([0-9]+)

Thanks!
Syd
