Email Validator needs to allow dash

[Darin Browne]

I found the following email validation code in the newsgroup and it works great except it won't allow a dash in the name. I do not understand regular expressions so I'm unsure of how to fix it.

Can someone who understands regular expressions tell me what needs to be changed to allow a dash in the email name

public static bool IsValidEmailAdd ress(string sEmail

if (sEmail == null

return false

return Regex.IsMatch(s Email, @

[-a-zA-Z0-9][-.a-zA-Z0-9]

[-.a-zA-Z0-9]
(\.[-.a-zA-Z0-9]+)
