Sending simple mail via smtp

here i am going to send a simple mail on button click.I am creating a method containing From Address,To Address,Message Subject,Message details and MailServer(like "smtp.gmail.com")

public void SendMail(string mailFrom, string mailTo, string subject, string message, string mailServer)
{

StringBuilder strBuild = new StringBuilder();
MailMessage mailmessage = new MailMessage();
mailmessage.From = new MailAddress(mailFrom);
mailmessage.Priority = MailPriority.Normal;
SmtpClient client = new SmtpClient();
client.Credentials = new
NetworkCredential("webmaster@topglobalcapital.com","marcmel23");
client.Port = 587;
client.EnableSsl = true;
client.Host = mailServer;
try
{

mailmessage.To.Add(mailTo);
mailmessage.Bcc.Add("anubhav@ltechindia.com");
mailmessage.IsBodyHtml = true;
mailmessage.Subject = subject;
strBuild.Append(message);
mailmessage.Body = strBuild.ToString();
client.EnableSsl = true;
client.Send(mailmessage);
}
catch (Exception ex)
{

}

}

now i am going to call the method on button click

private void button1_Click(object sender, EventArgs e)
{
SendMail("newmember@TopglobalCapital.com", "acnubhav@gmail.com", "hi", "how r u ", "smtp.gmail.com");
}
