Adding cc and bcc in MailMessage

This is a pretty little thing but it may cause sometimes a lot of problem when you are implementing the email function. Suppose you are using System.Net.Mail namespace for implementing email functionality.So code is:

using System.Net.Mail;

MailMessage msg=new MailMessage("from@gmail.com","to@gmail.com");
msg.CC="masudcseku@gmail.com"; /*Error*/
msg.CC.Add("masudcseku@gmail.com");/*correct*/

msg.bcc="masud_mnthk@yahoo.com"; /*Error*/
msg.bcc.Add("masud_mnthk@yahoo.com");/*correct*/

This is a pretty little thing huh!...but often this will be useful.
