Need to retrieve the first number in a string

Hello Experts,

I need a mechanism to retrieve the first number in a string.

Ex: "This is a string 123 with numbers in it 456 ok?"

In the above example I'd need to retrieve 123 & ignore the 456.

Many Thanks,
Moe

The expression "\d+" combined with the Match method will give you this.

e.g.

using System.Text.RegularExpressions;

...

string number = Regex.Match(source, @"\d+").Value;

Open in new window


There is no error handling in the above, so if there is a chance that the target string contains no number, then the above needs some adjustment.
