I am trying to write a regex to get a full name in c# something like /("full_name_ac": ")\\w +, but not able to write.Please help me to write the regex that will always find the value under double quotes for full_name_ac

Answer 1

Your RegEx to extract a full_name_ac value out of this string should look like

(?<="full_name_ac": ")[\w\ ]+(?=\")

Explaination:

(?<="full_name_ac": ") - starts with "full_name_ac": " but it's not a part of the value

[\\w\\ ]+ the name including space with at lease one character

(?=\\") and the string has to end with a " which isn't a part of the value
