ASP.NET C# programming help - validator?

Question

Hello.. I'm doing an assignment in web developing using C#.. I'm required to make a validator, so that the value entered in a textbox is a valid SMU email. The valid SMU email is ....@sis/accountancy/socsc/business/economics.smu.edu.sg

I've placed a regular expression validator, but i'm confused how to validate, what to put (such as \w,\d, or??).

Appreciate your helps. =)

correction : the valid smu email

.....@sis/accountancy/business/socsc/economics.smu.edu.sg

Answer 1

' Validate an e-mail address
' Example:
' MessageBox.Show(IsValidEmail("[e-mail]")) ' True
' MessageBox.Show(IsValidEmail("vb2themax.com")) ' False
' MessageBox.Show(IsValidEmail("mbellinaso@vb2themax")) ' False

VB version:

Function IsValidEmail(ByVal email As String) As Boolean
Return System.Text.RegularExpressions.Regex.IsMatch(email, _
"^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$")
End Function

As C#:
bool IsValidEmail(string email)
{
return System.Text.RegularExpressions.Regex.IsMatch(email, "^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$");
}
