[Solved] Check string format consist of specific words then number then specific words in c# [closed]

It’s really easy to make a regular expression to get matches:

        string[] input = new string[6]
        {
            "[email protected]", // match
            "[email protected]", // match
            "[email protected]", // match
            "[email protected]", // not a match
            "[email protected]", // not a match
            "[email protected]" // not a match
        };

        string pattern = @"Auto_gen_\d{4}@mail.com";  //\d{4} means 4 digits
        foreach (string s in input)
        {
            if (Regex.IsMatch(s, pattern))
            {
                Console.WriteLine(string.Format("Input {0} is valid",s));
            }
            else {
                Console.WriteLine (string.Format("Input {0} is  not valid",s));
            }
        }
        Console.ReadKey();
