public string Host { get; }

Property Value

Type: System.String
A String that contains the name of the host computer that accepts e-mail for the User property.

In a typical e-mail address, the host string includes all information following the "@" sign. For example, in "tsmith@contoso.com", the host is "contoso.com".

The following code example displays the destination of an e-mail message.

		public static void CreateTestMessage3()
		{
			MailAddress to = new MailAddress("jane@contoso.com");
			MailAddress from = new MailAddress("ben@contoso.com");
			MailMessage message = new MailMessage(from, to);
			message.Subject = "Using the new SMTP client.";
			message.Body = @"Using this new feature, you can send an e-mail message from an application very easily.";
			// Use the application or machine configuration to get the  
			// host, port, and credentials.
			SmtpClient client = new SmtpClient();
			Console.WriteLine("Sending an e-mail message to {0} at {1} by using the SMTP host={2}.",
				to.User, to.Host, client.Host);
      try {
			  client.Send(message);
			}
			catch (Exception ex) {
			  Console.WriteLine("Exception caught in CreateTestMessage3(): {0}", 
                    ex.ToString() );			  
		  }
		}

        MailAddress* from = new MailAddress(S"ben@contoso.com");
        MailMessage* message = new MailMessage(from, to);
        message->Subject = S"Using the new SMTP client.";
        message->Body = S"Using this new feature, you can send an e-mail message from an application very easily.";
        // Use the application or machine configuration to get the 
        // host, port, and credentials.
        SmtpClient* client = new SmtpClient();
        Console::WriteLine(S"Sending an e-mail message to {0} at {1} by using the SMTP host {2}.", 
            to->User, to->Host, client->Host);
