Question

我正在尝试在我的网站上建立联系表单，我正在使用带有C＃的asp.net，当我提交邮件时它没有到达电子邮件，是因为我使用本地服务器？或者我的代码有错误？我在catch部分收到此错误消息：“您的消息无法发送，请再试一次。”

这是页面C＃

背后的代码

try
{
    //Create the msg object to be sent
    MailMessage msg = new MailMessage();
    //Add your email address to the recipients
    msg.To.Add("jasmine.afnan@gmail.com");
    //Configure the address we are sending the mail from
    MailAddress address = new MailAddress("jasmine@gmail.com");
    msg.From = address;
    //Append their name in the beginning of the subject
    msg.Subject = txtName.Text + " :  " + ddlSubject.Text;
    msg.Body = txtMessage.Text;

    //Configure an SmtpClient to send the mail.
    SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
    client.EnableSsl = true; //only enable this if your provider requires it
    //Setup credentials to login to our sender email address ("UserName", "Password")
    NetworkCredential credentials = new NetworkCredential("jasmine.afnan@gmail.com", "*");
    client.Credentials = credentials;

    //Send the msg
    client.Send(msg);

    //Display some feedback to the user to let them know it was sent
    lblResult.Text = "Your message was sent!";

    //Clear the form
    txtName.Text = "";
    txtMessage.Text = "";
}
catch
{
    //If the message failed at some point, let the user know
    lblResult.Text = "Your message failed to send, please try again.";
}

这是例外
