smtp - change sender address when sending mail through gmail in c#

Question

I have used the following code to send mail from my web application using a gmail account. My question is, can i change the sender address to another address other than original sender(gmail) address? My code is as follows:

System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
System.Net.NetworkCredential cred = new System.Net.NetworkCredential("sample@gmail.com", "*******");

Whatever i do is useless as i always receive mail from sample@gmail.com. Is it possible to change it?

I have changed to mail.From = new System.Net.Mail.MailAddress("sample@yahoo.com"); but i received the mail with the from address sample@gmail.com and not from the new "From" address. I think gmail smtp overwrites the from address with the original credential.

Answer 1

This is the solution:

1. use the codes above to set mail.From = new MailAddress(address, display name)
2. in Gmail, go to Mail Settings >> Accounts and Import.
3. Add the email account you will use as sender in "Send Mail As". (tick as Alias)

This works for me
