Try the following:

using (var client = new SmtpClient("smtp.gmail.com", 587))
{
    client.EnableSsl = true;
    client.UseDefaultCredentials = false;
    client.Credentials = new NetworkCredential("username", "password");
    var message = new MailMessage(
        "sender@gmail.com", 
        "recipient@domain.com", 
        "some subject", 
        "mail body"
    );
    client.Send(message);
}

Also make sure that you are not behind a proxy and that the computer you are running this program on has access to smtp.gmail.com and that port 587 is not blocked by a firewall.

He does not recognize the using – Israel Aug 07 '11 at 16:46
the using:using (var client = new SmtpClient("smtp.gmail.com", 587)) – Israel Aug 07 '11 at 16:49
@Israel, that's because starting from .NET 4.0 the `SmtpClient` class implements `IDisposable`. If you are getting this error it means that you are targeting an older version. If this is the case, you will indeed have to remove the `using` clause. – Darin Dimitrov Aug 07 '11 at 16:50
so what do i do with the old virsion ? – Israel Aug 07 '11 at 17:13
@Israel, you remove the `using` clause. – Darin Dimitrov Aug 07 '11 at 17:13
I do not know what to remove you could write code that will work for me please? – Israel Aug 07 '11 at 20:29
Can someone please write me what I should write – Israel Aug 08 '11 at 12:36
