Simple Regex Example in C#

Sometimes you just need a quick example of something you know how to do, but you can't remember the syntax for since you only need to use it from time to time.

using System;
using System.Text.RegularExpressions;

class Program 
{
   static void Main()
   {
      Regex rx = new(@":(\d+)-");

      string text = "File:24524-abc.txt";

      Match match = rx.Match(text);

      if (match.Success)
      {
         Console.WriteLine(match.Groups[1].Value);
      }
   }
}
