Regular expression extraction

I have an data which may vary in each other place like Qty-35 or 35 Cpy or 35, I need to extract the only numbers from this data please help me in providing the appropriate Syntax or Regular Expression in extracting only the number.

string v1 = "Qty-35 or 35 Cpy or 35"

assign v1 = System.Text.RegularExpressions.Regex.Match(v1,"\d+").value

you can get result 35

Actually these data whichever mentioned is in the body of the mail and it may be like
Norton Callen’s Ultrasonography in Obstetrics and Gynecology:
First South Asia Edition
Qty - 34
in one mail body and
Basic Immunology : Functions and Disorders of the Immune
System (First South Asia Edition PB—Abbas— 1 copy
In another mail body.
Please help me in extracting only the number

This Regex pattern will give you numbers only : \d+

Regex.Match(your_Mail_body_String, “\d+”).Value

\d with + quantifire Matches between one and unlimited times, as many times as possible, giving back as needed by following greedy approach :slight_smile:

This regex will select every number after SPACE DASH SPACE " - " on the same line:
(?<= - )\d+

This regex will select every character:
(?<= - ).+
(in case you need to match after a comma or dot)
