I want to count the number of a regex pattern exist in a string. The regex pattern is “#\d{8}”.
How can I do that?

@Emily_Yip try this use your regex,matches
then store the result in MatchCollection then you can use tat varible to get the count yourMatchCollection _Varible.count
Thanks @kadiravan_kalidoss
And I have a string of #111111111#22222222
and I want to extract string of 8 digit after #.
Val = 11111111, val2 = 22222222 and store into list.
Do anyone has idea how to do that?
(?<=#)\d{8}
Hello @Emily_Yip
Yes you can do that by Casting the matches value you get…
Assign This code to a List<of String>
datatype variable
System.Text.RegularExpressions.Regex.Matches(Strrr,"(?<=#)\d{8}").Cast(of match).Select(Function(r) (r).tostring ).tolist
This will give you all the values in a list of string
If you want it in an integer you just have to add Convert to method just like this
System.Text.RegularExpressions.Regex.Matches(Strrr,"(?<=#)\d{8}").Cast(of match).Select(Function(r) Convert.ToInt32(r) ).tolist
Check it out and let me know about it
