Getting number from a string in C#

Question

I am scraping some website content which is like this - "Company Stock Rs. 7100".

Now, what i want is to extract the numeric value from this string. I tried split but something or the other goes wrong with my regular expression.

Please let me know how to get this value.

Answer 1

Use:

var result = Regex.Match(input, @"\d+").Value;

If you want to find only number which is last "entity" in the string you should use this regex:

\d+$

If you want to match last number in the string, you can use:

\d+(?!\D*\d)

Answer 2

int val = int.Parse(Regex.Match(input, @"\d+", RegexOptions.RightToLeft).Value);
