dim value as string = "noemail"
Dim emailc As New RegularExpressionValidator
emailcc.ControlToValidate = value
emailcc.ValidationExpression = "^[\w-\.]+@([\w-]+\.)+[\w-]{2,3}$"
Dim x As String = emailc.IsValid

why it gives me "true"?
where is the mistake?

Hi,
The default value for IsValid is true. The actual value will be available
only after you called the Validate method on the validator control.
Also, the ControlToValidate should be the ID of the server control to be
validated. Not the string value you want to validate.

dim value as string = "noemail"
Dim emailc As New RegularExpressionValidator
emailcc.ControlToValidate = value
emailcc.ValidationExpression = "^[\w-\.]+@([\w-]+\.)+[\w-]{2,3}$"
Dim x As String = emailc.IsValid

Indeed,
To do what you want to do, look at the
System.Text.RegularExpressions.Regex.IsMatch() shared method.

thankyou guys!
ive done!
i was using a wrong class
at the end this was the correct one:

Dim regex As New
System.Text.RegularExpressions.Regex("^[\w-\.]+@([\w-]+\.)+[\w-]{2,3}$")

Dim match As System.Text.RegularExpressions.Match

match = regex.Match(ExistingEmail)

If Not match.Success Then

MsgErrore = MsgErrore & "Not correct email!<br>"

End If
