Question

这是我尝试过的代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Web;
using System.Net.Mail;

namespace WindowsFormsApplication6
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();


        }

        private void Send_Click(object sender, EventArgs e)
        {



                MailMessage reece = new MailMessage("FromEmail", "ToEmail", "Hello", "How are you");
                SmtpClient smtp = new SmtpClient();
         smtp.Credentials = new System.Net.NetworkCredential("MyEmail", "MyPassword");
                smtp.Port = 465;

                smtp.Host = "smtp.gmail.com";
                smtp.EnableSsl = true;
                smtp.Send(reece);
                MessageBox.Show("Sent");
        }
    }
}

我一直在超时。尝试了很多不同的端口组合。

Answer 1

您尝试连接的服务器需要启用SSL。

smtp.EnableSsl = true;

同时将端口更改为995或465。
