Validating email address

[phreaky]

Anyone has a code for validating email address (offline), I mean, to validate that the user type a good format (user@host.ext) in email txtbox? VB talking of course.

Straight from MSDN:

Regex.IsMatch(address, @"^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$")

Well...thanks Ingis, but I dont know how to use what you gave me, because "Regex" is not a native function of VB, could you please teach me a little more about it? Sorry to bother, Im kinda newbie with VB .NET, Im using a txtbox, so, could you give me a piece of code using my txt_cariable.text, so I can use it? Thanks anyway for you concerning.

At the top of your source file add the line

Imports System.Text.RegularExpressions

and things should be okay.
