You may use

@"^[A-Za-z0-9\s@]*$"

See the regex demo

The pattern matches:

  • ^ - start of the string
  • [A-Za-z0-9\s@]* - zero or more (*, if you do not want to match an empty string, use +, 1 or more) occurrences of ASCII letters, digits, any whitespace and @ chars
  • $ - end of string (replace with \z if you do not want to match if the matching string ends with \n char).
