推荐答案
您需要提供SMTP服务器名称，希望这段代码可以帮助您理解
You need to provide the SMTP server name, I hope this piece of code might help you in understanding
using System;
using System.Windows.Forms;
using System.Net.Mail;
namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
try
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("your_email_address@gmail.com");
mail.To.Add("to_address@mfc.ae");
mail.Subject = "Test Mail";
mail.Body = "This is for testing SMTP mail from GMAIL";
SmtpServer.Port = 587;
SmtpServer.Credentials = new System.Net.NetworkCredential("username", "password");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
MessageBox.Show("mail Send");
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
}
}
尝试一下，
Try this,
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Mail;
using System.ComponentModel;
using System.Windows.Forms;
namespace DataSimulator
{
class EmailFunctions
{
//ayarlar
public SmtpClient client = new SmtpClient();
public MailMessage msg = new MailMessage();
public System.Net.NetworkCredential smtpCreds = new System.Net.NetworkCredential("frommailaddress@gmail.com", "frommailpassword");
public void SendMail(String sendTo, String sendFrom, String subject, String body)
{
try
{
//smtp client configurations
client.Host = "smtp.gmail.com";
client.Port = 587; //gmail smtp port number "587"
client.UseDefaultCredentials = false;
client.Credentials = smtpCreds;
client.EnableSsl = true;
MailAddress to = new MailAddress(sendTo);
MailAddress from = new MailAddress(sendFrom);
//mail mesajı ayarları
msg.Subject = subject;
msg.Body = body;
msg.From = from;
msg.To.Add(to);
//gönderme işlemi
client.Send(msg);
MessageBox.Show("successfull", "success");
}
catch(Exception ex)
{
MessageBox.Show(ex.Message,"unsuccessfull!");
}
}
}
}
使用此代码为您的邮件内容和类创建html以发送邮件
Use this code create html for your mail content and class to send mail
namespace MailerService
{
public class MailerController
{
public static void SendUserConfirmationMail(User _user)
{
Mailer mailers = new Mailer();
mailers.RecipientsEmailId = "abc@abc.com";
mailers.RecipientsName = _"Test";
mailers.Subject = "Testing Mail";
mailers.MessageSendingTime = DateTime.Now;
mailers.UserName = "Abc";
MailHelper mailHelper = new MailHelper();
mailHelper.SendMail(mailers, "Test.htm");
}
}
}

public void SendMail(Mailer mailers, string filePath)
{
StringBuilder sb = new StringBuilder();
