Regular expression to get last 3 characters of a string
c#, regex
Solution
Use this regular expression :
.{3}$
If you want to avoid spaces at end and can use capturing groups (you didn't precise the language or regex flavour), use
(.{3})\s*$
But note that there's no obvious reason to use a regex here instead of slicing the string.
Problem
I want to write a regular expression which will take only last 3 char of a string and append some constant string to it. I am using C#. I am trying to make regular expression as database entry. Later Read this entry in application and do the transformation based on regex in C#. Something like : ``` stringVal.Trim().Substring(0, stringVal.Trim().Length - 3) + ".ConstantValue" ```
