EmailValidating event

This event is fired when an email is being validated. By handling this event, you can The following steps illustrate how to handle this event.

Handling EmailValidating event

1. Add using directives to your code to create aliases for existing namespaces and avoid having to type the fully qualified type names. The code looks similar to the following:

   C#	Copy Code
   using ComponentSoft.Net;

   VB.NET	Copy Code
   Imports ComponentSoft.Net

2. Create a new instance of the EmailValidator class.

   C#	Copy Code
   // Create a new instance of the EmailValidator class. EmailValidator client = new EmailValidator();

   VB.NET	Copy Code
   ‘ Create a new instance of the EmailValidator class. Dim client As New EmailValidator()

3. Now pass the e-mail list file you want to validate to the ValidateTextFile method. The code looks similar to the following:

   C#	Copy Code
   em.EmailValidating += em_EmailValidating; try { em.ValidateTextFile(“c:\\EmailList.txt”); } catch (EmailValidatorException exc2) { Console.WriteLine(“EmailValidatorException: “ + exc2.Message); }

   VB.NET	Copy Code
   AddHandler em.EmailValidating, AddressOf em_EmailValidating Try em.ValidateTextFile(“c:\EmailList.txt”) Catch exc2 As EmailValidatorException Console.WriteLine(“EmailValidatorException: “ & exc2.Message) End Try

Final example code

C#

Copy Code

static void Main() { EmailValidator em = new EmailValidator(); // Register an event handler. em.EmailValidating += em_EmailValidating; try { em.ValidateTextFile(“c:\\EmailList.txt”); } catch (EmailValidatorException exc2) { Console.WriteLine(“EmailValidatorException: “ + exc2.Message); } } static void em_EmailValidating(object sender, EmailValidatingEventArgs e) { // Skip validating email with domain name ‘mydomain.com’. if (e.EmailAddress.IndexOf(“@mydomain.com”) != -1) e.Skipped = true; }

VB.NET

Copy Code

Sub Main() Dim em As New EmailValidator() ‘ Register an event handler. AddHandler em.EmailValidating, AddressOf em_EmailValidating Try em.ValidateTextFile(“c:\EmailList.txt”) Catch exc2 As EmailValidatorException Console.WriteLine(“EmailValidatorException: “ & exc2.Message) End Try End Sub Private Sub em_EmailValidating(ByVal sender As Object, ByVal e As EmailValidatingEventArgs) ‘ Skip validating email with domain name ‘mydomain.com’. If e.EmailAddress.IndexOf(“@mydomain.com”) <> -1 Then e.Skipped = True End If End Sub
