How to hide email address

I am making an algorithm that sends emails, I am able to send the emails normally, but I would like to be able to hide the email address of the one who is sending to the recipient.

Note: when I talk about hiding the email address, I mean the email Header, in which the sender's name appears and the email address enters ''. I would like to hide the address who comes within the signs of minor and major.

Code C# :

    public HttpResponseMessage SendMail()
    {
        try
        {
            MailMessage _mailMessage = new MailMessage();

            _mailMessage.From = new MailAddress("emailRemetente", "nomeRemetente");

            _mailMessage.CC.Add(emailDestinatario);
            _mailMessage.Subject = "Título do email";
            _mailMessage.IsBodyHtml = true;
            _mailMessage.Body = "Corpo do email HTML";


            SmtpClient _smtpClient = new SmtpClient("smtpclient", Convert.ToInt32(porta));

            _smtpClient.UseDefaultCredentials = false;
            _smtpClient.Credentials = new NetworkCredential("emailRemetente", "senhaRemetente");

            _smtpClient.EnableSsl = true;

            _smtpClient.Send(_mailMessage);

            return Request.CreateResponse(HttpStatusCode.OK, true);
        }
        catch (Exception ex)
        {
            return Request.CreateResponse(HttpStatusCode.BadRequest, ex.Message);
        }
    }
}

I gave a read on this link : https://docs.microsoft.com/pt-br/dotnet/api/system.net.mail.mailmessage.bcc?view=netframework-4.8 but I didn't quite understand.
