Referencing Headers Part II

This example builds on Part I. Except, because of the static (shared) method, Header.EmptyHeader() on the header class, null headers can translated to empty strings. Thus negating the need for checking for nulls.  Compare this example to Referencing Headers Part I.

[C#]

using System;
using aspNetPOP3;
using aspNetMime;
namespace cstest
{
	class Class1
	{
		[STAThread]
		static void Main(string[] args)
		{
			//create a new pop3 object
			POP3 pop = new POP3("127.0.0.1","dave@blah.com", "mypassword" );
            
			//connect to the POP3 server
			pop.Connect();
                       
			//retrieve the first message
			MimeMessage msg = pop.GetMessage(1);

			//Close the POP3 Connection
			pop.Disconnect();

			//write out some of the headers, if they are null, Header.EmptyHeader() 
			returns an empty header, resulting in string.empty for values.
			Console.WriteLine( Header.EmptyHeader(msg.Subject).Value );
			Console.WriteLine( Header.EmptyHeader( msg.ContentType).Value );

			//reference an X-Header
			Console.WriteLine( Header.EmptyHeader( msg.Headers[ "X-Mailer" ]).Value );
            
			//done
			Console.WriteLine( "done.");
			Console.ReadLine( );
            
		}
	}
}
