MailMessage.To Property

Gets the address collection that contains the recipients of this e-mail message.

Namespace:  System.Net.Mail
Assembly:  System (in System.dll)

public MailAddressCollection To { get; }

Property Value

Type: System.Net.Mail.MailAddressCollection
A writable MailAddressCollection object.

The To property is used to designate the addresses on the To line of an e-mail message. To add a recipient to an e-mail message, create a MailAddress for the recipient's address, and then add that object to the collection returned by this property.

The following code example demonstrates setting the To property.

		public static void CreateTestMessage4(string server)
		{
			MailAddress from = new MailAddress("ben@contoso.com");
			MailAddress to = new MailAddress("Jane@contoso.com");
			MailMessage message = new MailMessage(from, to);
			message.Subject = "Using the SmtpClient class.";
			message.Body = @"Using this feature, you can send an e-mail message from an application very easily.";
			SmtpClient client = new SmtpClient(server);
			Console.WriteLine("Sending an e-mail message to {0} by using SMTP host {1} port {2}.",
				 to.ToString(), client.Host, client.Port);

      try {
			  client.Send(message);
			}
			catch (Exception ex) {
			  Console.WriteLine("Exception caught in CreateTestMessage4(): {0}", 
                    ex.ToString() );			  
		  }
		}
