Sending email through Gmail SMTP server with C#

The following c# function will let you send email using Google SMTP Server. All you need to do is just replace network credentials with your Google user name and password.

//Start Send Email Function
public string SendMail(string toList, string from, string ccList, string subject, string body)
{

    MailMessage message = new MailMessage();
    SmtpClient smtpClient = new SmtpClient();
    string msg = string.Empty;
    try
    {
        MailAddress fromAddress = new MailAddress(from);
        message.From = fromAddress;
        message.To.Add(toList);
        if (ccList != null && ccList != string.Empty)
            message.CC.Add(ccList);
        message.Subject = subject;
        message.IsBodyHtml = true;
        message.Body = body;
        smtpClient.Host = "smtp.gmail.com";   // We use gmail as our smtp client
        smtpClient.Port = 587;
        smtpClient.EnableSsl = true;
        smtpClient.UseDefaultCredentials = true;
        smtpClient.Credentials = new System.Net.NetworkCredential("[email protected]", "YourGmailPassword");

        smtpClient.Send(message);
        msg = "Email sent Successfully.";
    }
    catch (Exception ex)
    {
        msg = ex.Message;
    }
    return msg;
}
//End Send Email Function

Note: Before providing credentials, you need to set UserDefaultCredentials to false. And you can make a call to the above function by using:

Response.Write(SendMail(recipient Address, "[email protected]", "ccList if any", "subject", "body"))

I have tested this code and used it to send mails. You can even attach Files to the email, will update my post soon.. Cheers
