I am new to regex and recently faced this problem

Appending and Prepending ‘#’ in an string using only Regex

In this suppose we have string such as Hello my name is #First Name# @EducationDetail@

Now I have to append and prepend # in this using only regular expression so it will become

#Hello my name is #First Name# @EducationDetail@#

Thanks
