How woul

Answer 1

Here is one Non-Regex way :P

string str = "MD00494";
string digits = new string(str.Where(char.IsDigit).ToArray());
string letters = new string(str.Where(char.IsLetter).ToArray());

int number;
if (!int.TryParse(digits, out number)) //int.Parse would do the job since only digits are selected
{
    Console.WriteLine("Something weired happened");
}

string newStr = letters + (++number).ToString("D5");

output would be:

newStr = "MD00495"
