Download Messages' Headers into a DataTable

The following example demonstrates downloading messages 3 - 5 as a DataTable.  It then binds the DataTable to a DataGrid to be displayed in an ASP.NET Web Page.

The DataTable contains the following columns:

1. Int32 MessageNumber -- The message number as found at the POP3 server.

2. String Headers -- All of the headers

3. String FromName -- The 'Name' part of the FROM header

4. String FromAddress -- the 'Address' part of the FROM header

5. String To -- The 'To' address header

6. String CC -- The 'CC' address header

7. String Subject -- The 'Subject' address header

8. String Date -- The 'Date' address header

9. String ContentType -- The 'type/subtype' of the Content-Type header

            //create a new pop3 object
            POP3 pop = new POP3("127.0.0.1","dave@blah.com", "mypassword" );
            
            //connect to the POP3 server
            pop.Connect();
                        
            //download the headers for messages 3 - 5 (inclusive)
            DataTable dt = pop.HeaderTable(3, 5);
            
            
            //Close the POP3 Connection
            pop.Disconnect();
            
            
            //html encode the cells
            for( int r=0;r<dt.Rows.Count;r++)
            {
            	//skip the first col because it's an Int32
            	for( int c=1;c<dt.Columns.Count;c++)
            	{
            		string cellValue = dt.Rows[r][c].ToString();
