try this code
protected void btn_send_Click(object sender, EventArgs e)
{

    System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
    mail.To.Add("to gmail address");
    mail.From = new MailAddress("from gmail address", "Email head", System.Text.Encoding.UTF8);
    mail.Subject = "This mail is send from asp.net application";
    mail.SubjectEncoding = System.Text.Encoding.UTF8;
    mail.Body = "This is Email Body Text";
    mail.BodyEncoding = System.Text.Encoding.UTF8;
    mail.IsBodyHtml = true;
    mail.Priority = MailPriority.High;
    SmtpClient client = new SmtpClient();
    client.Credentials = new System.Net.NetworkCredential("from gmail address", "your gmail account password");
    client.Port = 587;
    client.Host = "smtp.gmail.com";
    client.EnableSsl = true;
    try
    {
        client.Send(mail);
        Page.RegisterStartupScript("UserMsg", "");
    }
    catch (Exception ex)
    {
        Exception ex2 = ex;
        string errorMessage = string.Empty;
        while (ex2 != null)
        {
            errorMessage += ex2.ToString();
            ex2 = ex2.InnerException;
        }
        Page.RegisterStartupScript("UserMsg", "");

Hi,

Instead of 465 Use 587 port id.
SmtpClient client = new SmtpClient("smtp.gmail.com", 587); //Gmail smtp

I try this code but still I cannot send mail.
protected void Page_Load(object sender, EventArgs e)
{
string to = "[email protected]"; //To address
string from = "[email protected]"; //From address
MailMessage message = new MailMessage(from, to);
string mailbody = "In this article you will learn how to send a email using Asp.Net & C#";
message.Subject = "Sending Email Using Asp.Net & C#";
message.Body = mailbody;
message.BodyEncoding = Encoding.UTF8;
message.IsBodyHtml = true;
SmtpClient client = new SmtpClient("smtp.gmail.com", 465); //Gmail smtp
System.Net.NetworkCredential basicCredential1 = new
System.Net.NetworkCredential("[email protected]", "12345");
client.EnableSsl = true;
client.UseDefaultCredentials = false;
client.Credentials = basicCredential1;
try
{
client.Send(message);
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}

Hi,

First of all check the given gmail smtp port id is "587" then it will work. You need to check more about sending mail using C#.
Please check my article and blog content for solving Gmail mail sending issues.

Hi,
Can you try following code ?
public string SendEmail(string SendTo, string Subject, string MessageBody)
{
try
{
MailMessage mailmsg = new MailMessage("EMAIL ID", SendTo, Subject, MessageBody);
mailmsg.IsBodyHtml = true;
mailmsg.BodyEncoding = System.Text.Encoding.ASCII;
SmtpClient client = new SmtpClient("SMTP", 25);
client.UseDefaultCredentials = false;
//client.EnableSsl = true;
client.Credentials = new NetworkCredential("EMAIL ID", "PASSWORD");
client.Send(mailmsg);
}
catch (Exception ex)
{
return ex.ToString();
}
return "1";
}
