My code is:

C#

MailMessage msg = new MailMessage();
           msg.From = new MailAddress("abc@xyz.com");
           msg.To.Add(new MailAddress(To));
           string body = "Body of Message.";

           msg.Subject = "Subject";
           msg.Body = body;
           msg.IsBodyHtml = true;
           NetworkCredential Login = new NetworkCredential("EmailID", "Password");
           SmtpClient client = new SmtpClient("smtp.gmail.com");
           client.EnableSsl = Convert.ToBoolean(true);
           client.UseDefaultCredentials = false;
           client.Credentials = Login;
           client.Send(msg);

Use this code

SmtpClient client = new SmtpClient("your smtpAddress", YourSmtpPort);
MailMessage msg = new MailMessage();

MailAddress from = new MailAddress(TextBoxFrom.Text);
MailAddress to = new MailAddress(TextBoxTo.Text);

string subjectText = subject;
string bodyText = body;

msg.To.Add(to);
msg.From = from;
msg.Subject = subjectText;
msg.Body = bodyText;
msg.IsBodyHtml = true;
msg.Priority = MailPriority.Normal;

if ((TextBoxCc.Text != null) && (TextBoxCc.Text != ""))
{
MailAddress cc = new MailAddress(TextBoxCc.Text);
msg.CC.Add(cc);
}
if ((TextBoxBcc.Text != null) && (TextBoxBcc.Text != ""))
{
MailAddress bcc = new MailAddress(TextBoxBcc.Text);
msg.Bcc.Add(bcc);
}

client.Send(msg);

You did not declare the port. It is required. Default port 21 will not be going to work in gmail.

Here is the typical code for sending mail using gmail smtp

using System.Net;
using System.Net.Mail;

var fromAddress = new MailAddress("youremail@gmail.com", "Your Name");
var toAddress = new MailAddress("test@test.com", "To Name");
const string fromPassword = "password";
const string subject = "Subject";
const string body = "Body";

var smtp = new SmtpClient
           {
               Host = "smtp.gmail.com",
               Port = 587,
               EnableSsl = true,
               DeliveryMethod = SmtpDeliveryMethod.Network,
               UseDefaultCredentials = false,
               Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
           };
using (var message = new MailMessage(fromAddress, toAddress)
           {
                Subject = subject,
                Body = body
           })
{
    smtp.Send(message);
}

cheers
