Question

In my current project I have to work alot with substring and I’m wondering if there is an easier way to get out numbers from a string.

Example:
I have a string like this:
12 text text 7 text

I want to be available to get out first number set or second number set.
So if I ask for number set 1 I will get 12 in return and if I ask for number set 2 I will get 7 in return.

Thanks!

This will create an array of integers from the string:

using System.Linq;
using System.Text.RegularExpressions;

class Program {
    static void Main() {
        string text = "12 text text 7 text";
        int[] numbers = (from Match m in Regex.Matches(text, @"\d+") select int.Parse(m.Value)).ToArray();
    }
}
