Regex pattern not matching input string
c#, regex
Solution
You need to use `\d` for digits:
Regex.IsMatch("SX25536101", @"^[S][STWXV]\d{6}[A-Z0-9]{2}$"); // true
NOTE: Here is nice Regular Expressions Cheat Sheet which can help you in future.
Problem
I need to find a pattern that restricts the input of data. What I need it to restrict input to: First character must be "S" Second character must be "S", "T", "W", "X" or "V" The next 6 must be numbers for 0 - 9 The last 2 can be any capital letter or any number 0 - 9 So my research led me to put this together..... `^[S][STWXV]/d{6}[A-Z0-9]{2}$` From what I read: `[S]` mean the capital letter S only `[STWXV]` means any one letter from this list `/d{6}` means 6 digits `[A-Z0-9]{2}` means any 2 characters A - Z or 0 - 9 I am not looking for a match anywhere in a string, i need the whole string to match this pattern. So why does `Regex.IsMatch("SX25536101", "^[S][STWXV]/d{6}[A-Z0-9]{2}$")` return false? Ive obviously gone wrong somewhere but this is my first attempt at Regular Expressions and this makes no sense :(
