Tutorial :regular expression: extract last 2 characters


what is the best way to extract last 2 characters of a string using regular expression.

For example, I want to extract state code from the following


I want to extract IL as string..

please provide me C# code on how to get it..

string fullexpression = "A_IL";  string StateCode = some regular expression code....  



Use the regex:


This will return provide the two characters next to the end anchor.

Since you're using C#, this would be simpler and probably faster:

string fullexpression = "A_IL";  string StateCode = fullexpression.Substring(fullexpression.Length - 2);  


Use /(..)$/, then pull group 1 (.groups(1), $1, \1, etc.).
