Removing invalid characters from price

Question

I have a scenario where I have to remove certain characters from a price string using C#.

I\'m looking for a regular expression to remove these characters or somethi

Answer 1

Regular expressions are always tricky to get right, since the input can vary so greatly, but I think this one covers your needs:

string pattern = @"([\d]+[,.]{0,1})+";
string cleanedPrice = Regex.Match(price, pattern).Value;

Explained:

(         - start matching group
[\d]+     - match any decimal digit, at least once
[,.]{0,1} - ...followed by 0 or 1 comma or dot
)         - end of group
+         - repeat at least once
