我正在一个页面上工作，我必须用C#发送电子邮件。我按照http://blogs.msdn.com/b/mariya/archive/2006/06/15/633007.aspx上的代码，遇到了这两个异常

在System.dll中发生类型为“System.Net.Mail.SmtpException”的首次机会异常。在mscorlib.dll中发生类型为“System.Threading.ThreadAbortException”的首次机会异常

这是我实现的代码。我似乎不知道哪里出了问题。

//Send email notification - removed actual email for this question

SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
client.EnableSsl = true;

MailAddress from = new MailAddress("myemail@gmail.com", "My name is here");
MailAddress to = new MailAddress("anotherpersonsemail@gmail.com", "Subject here");

MailMessage message = new MailMessage(from, to);
message.Body = "Thank you";
message.Subject = "Successful submission";

NetworkCredential myCreds = new NetworkCredential("myemail@gmail.com",         
"mypassword", "");

client.Credentials = myCreds;
try
{
  client.Send(message);
  Console.Write(ex.Message.ToString());

}

catch (Exception ex)
{
  Console.Write(ex.Message.ToString());
}

出于共享的目的，我设法解决了我的问题，通过启用访问Gmail中不太安全的应用程序。它现在的工作就像一个魅力！https://www.google.com/settings/security/lesssecureapps
要在Outlook中验证SMTP，下面的文章也非常有用。http://www.tradebooster.com/web-hosting-articles/how-to-enable-smtp-authentication-in-outlook-2010/

在Google在Google帐户中引入了两步验证系统后，要将Gmail用于个人用途并不容易，因此为了解决这个问题，我想出了一种方法，使用Gmail作为电子邮件媒介，使用C#发送电子邮件。
电子邮件服务的C#程式码包含在这里：******
