Question

I’m trying to figure out how to write a pattern that can match to both “3Z10Z” and “3Z 10Z”, and then return “3Z”. (Later I will write the pattern to return the 10Z part…).

I tried using something like @"\d+Z\s*\B" to try and grab the first part, but no dice. One thought I have, if its possible, is for it to read left to right and return the first @”\d+Z” it finds. To later get the “10Z” part I would need it to read from right to left though…

Any help is much appreciated!

Have you tried @"(\d[A-Z])\s*(.*)" ?

If you run the program below you can capture both the prefix and suffix in one shot

Basically a digit followed by upper case letter.

        static void Main(string[] args)
        {
            string text1 = "3Z10Z";
            string text2 = "3Z 10Z";
            string pattern = @"(\d[A-Z])\s*(.*)";

            Match match = Regex.Match(text1, pattern);
            if (match.Success)
            {
                Console.WriteLine("prefix {0} suffix {1}.", 
                  match.Groups[1].Value, match.Groups[2].Value);
            }

            match = Regex.Match(text2, pattern);
            if (match.Success)
            {
                Console.WriteLine("prefix {0} suffix {1}.", 
              match.Groups[1].Value, match.Groups[2].Value);
            }

            Console.ReadLine();
        }
