Email Validation Function in D365 using X++

Validation of email is one of the feature that has been most commonly used in Dynamics AX. We being a developer many times came across with the requirements that needs email validation so i have written a function that uses regex regular expression to validate emails.
Retirements:
1)We need to declare a const str in the class that will contain all characters,
public const Str MatchEmailPattern =
       @"^(([\w-]+\.)+[\w-]+|([a-zA-Z]{1}|[\w-]{2,}))@"
     + @"((([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\.([0-1]?
       [0-9]{1,2}|25[0-5]|2[0-4][0-9])\."
     + @"([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\.([0-1]?
       [0-9]{1,2}|25[0-5]|2[0-4][0-9])){1}|"
     + @"([\w-]+\.)+[a-zA-Z]{2,4})$";
2) The above, MatchEmailPattern will be called within the function "validateEmail" that will return boolean


//function "validateEmail"
 private boolean validateEmail(Email _email)
    {
        boolean   ret = true;
        Boolean   VerifEmails;
        
        System.Text.RegularExpressions.Match emailMatch;
    

        if(_email != '')
        {
            new InteropPermission(InteropKind::ClrInterop).assert();
            emailMatch =        System.Text.RegularExpressions.Regex::Match(_email,MatchEmailPattern);
            VerifEmails = emailMatch.get_Success();
            ret = VerifEmails;
            CodeAccessPermission::revertAssert();
        }
         
        return ret;
    }
