I want to Extract only the Mail in a given string using RegExp

Question

the Given string :

/CN=RECIPIENTS/[email protected]

/CN=RECIPIENTS/[email protected]

OUTPUT :

 [email protected]

[email protected]

I m using this pattern but it is not working

^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$

Please [see here](https://stackoverflow.com/questions/46155/how-to-validate-an-email-address-in-javascript). The topic of writing a regex to cover an email address has already been well covered on this site. — Tim Biegeleisen, Mar 15 '19 at 06:04
`@` is present only in `[email protected]` ? means no any occurence of `@` except email? — er-sho, Mar 15 '19 at 06:26

Try this . I try this according to the above sample. I you add some other sample string so it would be great to write strong regex.

Regex:

[a-zA-Z]+@[a-zA-Z]+[.][a-zA-Z]+

One possible solution to retrieve email from your input string is,

1) Split your string by hyphen(-).

2) Take the 3 splitted string with index [2].

3) And remove digits from splitted string.

string input = "/CN=RECIPIENTS/[email protected]";

string output = new string(input.Split('-')[2].Where(x => !char.IsDigit(x)).ToArray());

Output:

Note: The above code only works for OP's provided input.
