How send mail with contact information in asp.net...

This code is for gmail server.

using system;
using system.net.mail; 

protected void btnSend_Click(object sender, EventArgs e)
    {
        MailMessage msg = new MailMessage();
        MailAddress mailfrom = new MailAddress("from@gmail.com");
        msg.To.Add( "to@example.com");
        msg.From = mailfrom;
        msg.CC.Add("some@example.com");
        msg.Bcc .Add("some@gmail.com");
        msg.Body = "name:"+txtname.Text+"\n"+"Address:"+txtAddress.Text+"\n"+"phoneno:"+txtPhone.Text+"\n";
        msg.Subject = "sending code for email sending";
        SmtpClient smtp = new SmtpClient("localhost");
        smtp.Host = "smtp.gmail.com";
        smtp.Credentials = new System.Net.NetworkCredential("username@gmail.com", "mypassword");
        smtp.Send(msg);
        

    }

If your having smtp in your system then you can use this code
smtp.Host="localhost";Instead of (smtp.Host = "smtp.gmail.com";)
no need of using credentials here.

sendEmail("Test Subject", "me@mail.com", "user1@mail.com,user2@mail.com,user3@mail.com", "Body of email", "", "",null);
 
public static bool sendEmail(string strSubject, string strFrom, string strTo, string strBody, string strCc, string strBcc,string displayName)
{
System.Net.Mail.SmtpClient Mail = new System.Net.Mail.SmtpClient();
Mail.Host = clsCommon.value("SMTPServer").ToString();
 
 
string username = null;
string Password = null;
 
Mail.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
username = "MailUserName";
Password = "MailPassword";
System.Net.NetworkCredential basicAuthenticationInfo = new System.Net.NetworkCredential(username, Password);
 
Mail.UseDefaultCredentials = false;
Mail.Credentials = basicAuthenticationInfo;
 

 
System.Net.Mail.MailMessage myMail = new System.Net.Mail.MailMessage();
myMail.Subject = strSubject;
 
myMail.From = new System.Net.Mail.MailAddress(strFrom,displayName);
myMail.To.Add(new System.Net.Mail.MailAddress(strTo));
if (!string.IsNullOrEmpty(strCc))
{
myMail.CC.Add(new System.Net.Mail.MailAddress(strCc));
}
if (!string.IsNullOrEmpty(strBcc))
{
myMail.Bcc.Add(new System.Net.Mail.MailAddress(strBcc));
}
 
myMail.IsBodyHtml = true;
myMail.Body = strBody;
try
{
 
Mail.Send(myMail);
 
 
return true;
}
catch (Exception ex)
{
ex.Message.ToString();
return false;
}
}
