Sending a password via e-mail is a bad idea someone can spy on your communication and get the password.

Not everyone knows that there is a secure way to exchange secret information through absolutely open channels of communication and keep the messages in secret even from the one who was spying on the channel since before both participants were burn. So many people argues with me that this is impossible! They argued that if as soon as the two partners need to say "something special" to each other, the man in the middle can here it, too. Such considerations are based on a subtle logical flaw.

Nevertheless, such methods are widely known under the common name public-key cryptography:

Follow the action taken by Alice and Bob to make sure was right.

Such algorithms are well available in .NET. Please see:

try this,

MailAddress mailfrom = new MailAddress ( "frommail@gmail.com" );
MailAddress mailto = new MailAddress ( "tomail@gmail.com" );
MailMessage newmsg = new MailMessage ( mailfrom, mailto );

newmsg.Subject = "Subject of Email";
newmsg.Body = "Body(message) of email";

////For File Attachment, more file can also be attached

Attachment att = new Attachment ( "G:\\code.txt" );
newmsg.Attachments.Add ( att );

SmtpClient smtps = new SmtpClient ( "smtp.gmail.com", 587 );
smtps.UseDefaultCredentials = false;
smtps.Credentials = new NetworkCredential             ( "mail@gmail.com", "pwd" );
smtps.EnableSsl = true;
smtps.Send ( newmsg );
