ASP.NET C #에서 이메일을 보내는 방법
저는 ASP.NET C # 영역을 처음 접했습니다 . ASP.NET C #을 통해 메일을 보낼 계획이며 이것은 ISP 의 SMTP 주소입니다 .
smtp-proxy.tm.net.my
아래는 내가 시도했지만 실패한 것입니다.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="SendMail" %>
<html>
<head id="Head1" runat="server"><title>Email Test Page</title></head>
<body>
<form id="form1" runat="server">
Message to: <asp:TextBox ID="txtTo" runat="server" /><br>
Message from: <asp:TextBox ID="txtFrom" runat="server" /><br>
Subject: <asp:TextBox ID="txtSubject" runat="server" /><br>
Message Body:<br>
<asp:TextBox ID="txtBody" runat="server" Height="171px" TextMode="MultiLine" Width="270px" /><br>

그리고 아래는 내 코드 숨김입니다 .
using System;
using System.Web.UI.WebControls;
using System.Net.Mail;
public partial class SendMail : System.Web.UI.Page
{
protected void Btn_SendMail_Click(object sender, EventArgs e)
{
MailMessage mailObj = new MailMessage(
txtFrom.Text, txtTo.Text, txtSubject.Text, txtBody.Text);
SmtpClient SMTPServer = new SmtpClient("127.0.0.1");
try
{
SMTPServer.Send(mailObj);
}
catch (Exception ex)
{
Label1.Text = ex.ToString();
}
}
}
추신 : 수신자 / 발신자 SMTP 개념을 이해하지 못해 죄송합니다. 그래서 여기서부터 전체 개념을 이해하려고합니다.
아래 코드를 살펴보십시오.
SmtpClient smtpClient = new SmtpClient("mail.MyWebsiteDomainName.com", 25);
smtpClient.Credentials = new System.Net.NetworkCredential("info@MyWebsiteDomainName.com", "myIDPassword");
smtpClient.UseDefaultCredentials = true;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.EnableSsl = true;
MailMessage mail = new MailMessage();
//Setting From , To and CC
mail.From = new MailAddress("info@MyWebsiteDomainName", "MyWeb Site");
mail.To.Add(new MailAddress("info@MyWebsiteDomainName"));
mail.CC.Add(new MailAddress("MyEmailID@gmail.com"));
smtpClient.Send(mail);
대신이 코드를 사용해보십시오. 참고 : "보낸 사람 주소"에 올바른 이메일 ID와 비밀번호를 입력하십시오.
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", "<script>alert('Successfully Send...');if(alert){ window.location='SendMail.aspx';}</script>");
}
catch (Exception ex)
{
Exception ex2 = ex;
string errorMessage = string.Empty;
while (ex2 != null)
{
errorMessage += ex2.ToString();
ex2 = ex2.InnerException;
}
Page.RegisterStartupScript("UserMsg", "<script>alert('Sending Failed...');if(alert){ window.location='SendMail.aspx';}</script>");
}
}
다음과 같이 핫메일을 사용하여 시도 할 수 있습니다.
MailMessage o = new MailMessage("From", "To","Subject", "Body");
NetworkCredential netCred= new NetworkCredential("Sender Email","Sender Password");
SmtpClient smtpobj= new SmtpClient("smtp.live.com", 587);
smtpobj.EnableSsl = true;
smtpobj.Credentials = netCred;
smtpobj.Send(o);
다음을 시도하십시오.
try
{
var fromEmailAddress = ConfigurationManager.AppSettings["FromEmailAddress"].ToString();
var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString();
var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString();
var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString();
var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString();
string body = "Your registration has been done successfully. Thank you.";
MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName), new MailAddress(ud.LoginId, ud.FullName));
message.Subject = "Thank You For Your Registration";
message.IsBodyHtml = true;
message.Body = body;
var client = new SmtpClient();
client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword);
client.Host = smtpHost;
client.EnableSsl = true;
client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0;
client.Send(message);
}
catch (Exception ex)
{
throw (new Exception("Mail send failed to loginId " + ud.LoginId + ", though registration done."));
}
그런 다음 web.config에서 다음을 추가하십시오.
<!--Email Config-->
<add key="FromEmailAddress" value="sender emailaddress"/>
<add key="FromEmailDisplayName" value="Display Name"/>
<add key="FromEmailPassword" value="sender Password"/>
<add key="SMTPHost" value="smtp-proxy.tm.net.my"/>
<add key="SMTPPort" value="smptp Port"/>
이것을 확인하십시오 .... 작동합니다

Razor 에서 이메일 본문을 생성하려면 Mailzory 를 사용할 수 있습니다 . 또한 여기 에서 nuget 패키지를 다운로드 할 수 있습니다 .
// template path
var viewPath = Path.Combine("Views/Emails", "hello.cshtml");
// read the content of template and pass it to the Email constructor
var template = File.ReadAllText(viewPath);
var email = new Email(template);
// set ViewBag properties
email.ViewBag.Name = "Johnny";
email.ViewBag.Content = "Mailzory Is Funny";
// send email
var task = email.SendAsync("mailzory@outlook.com", "subject");
task.Wait()
이것은 나를 위해 완벽하게 작동합니다.
public void sendEmail(string body)
{
if (String.IsNullOrEmpty(email))
return;
try
{
MailMessage mail = new MailMessage();
mail.To.Add(email);
mail.To.Add("test@gmail.com");
mail.From = new MailAddress("abc@gmail.com");
mail.Subject = "sub";
mail.Body = body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com"; //Or Your SMTP Server Address
smtp.Credentials = new System.Net.NetworkCredential
("yourgmail@gmail.com", "Yourpassword"); // ***use valid credentials***
smtp.Port = 587;
//Or your Smtp Email ID and Password
smtp.EnableSsl = true;
smtp.Send(mail);
}
catch (Exception ex)
{
print("Exception in sendEmail:" + ex.Message);
}
}
MailKit을 사용해 볼 수 있습니다. MailKit은 MimeKit을 기반으로하고 모바일 장치에 최적화 된 오픈 소스 크로스 플랫폼 .NET 메일 클라이언트 라이브러리입니다. 응용 프로그램에서 쉽게 사용할 수 있습니다 . 여기 에서 다운로드 할 수 있습니다 .
MimeMessage mailMessage = new MimeMessage();
mailMessage.From.Add(new MailboxAddress(fromName, from@address.com));
mailMessage.Sender = new MailboxAddress(senderName, sender@address.com);
mailMessage.To.Add(new MailboxAddress(emailid, emailid));
mailMessage.Subject = subject;
mailMessage.ReplyTo.Add(new MailboxAddress(replyToAddress));
mailMessage.Subject = subject;
var builder = new BodyBuilder();
builder.TextBody = "Hello There";
try
{
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("HostName", "Port", MailKit.Security.SecureSocketOptions.None);
smtpClient.Authenticate("user@name.com", "password");
smtpClient.Send(mailMessage);
Console.WriteLine("Success");
}
}
catch (SmtpCommandException ex)
{
Console.WriteLine(ex.ToString());
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
MailMessage mm = new MailMessage(txtEmail.Text, txtTo.Text);
mm.Subject = txtSubject.Text;
mm.Body = txtBody.Text;
if (fuAttachment.HasFile)//file upload select or not
{
string FileName = Path.GetFileName(fuAttachment.PostedFile.FileName);
mm.Attachments.Add(new Attachment(fuAttachment.PostedFile.InputStream, FileName));
}
mm.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
NetworkCredential NetworkCred = new NetworkCredential(txtEmail.Text, txtPassword.Text);
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = 587;
smtp.Send(mm);
Response.write("Send Mail");

테스트하기 가장 쉬운 스크립트입니다.
<%@ Import Namespace="System.Net" %>
<%@ Import Namespace="System.Net.Mail" %>
<script language="C#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
//create the mail message
MailMessage mail = new MailMessage();
//set the addresses
mail.From = new MailAddress("From email account");
mail.To.Add("To email account");
//set the content
mail.Subject = "This is a test email from C# script";
mail.Body = "This is a test email from C# script";
//send the message
SmtpClient smtp = new SmtpClient("mail.domainname.com");
NetworkCredential Credentials = new NetworkCredential("to email account", "Password");
smtp.Credentials = Credentials;
smtp.Send(mail);
lblMessage.Text = "Mail Sent";
}
</script>
<html>
<body>
<form runat="server">
<asp:Label id="lblMessage" runat="server"></asp:Label>
</form>
</body>
이것에 따르면 :
SmtpClient 및 해당 유형의 네트워크는 잘못 설계되었으므로 대신 https://github.com/jstedfast/MailKit 및 https://github.com/jstedfast/MimeKit 를 사용하는 것이 좋습니다 .
Reference : https://docs.microsoft.com/en-us/dotnet/api/system.net.mail.smtpclient?view=netframework-4.8
It's better to use MailKit to send emails :
var message = new MimeMessage ();
message.From.Add (new MailboxAddress ("Joey Tribbiani", "joey@friends.com"));
message.To.Add (new MailboxAddress ("Mrs. Chanandler Bong", "chandler@friends.com"));
message.Subject = "How you doin'?";
message.Body = new TextPart ("plain") {
Text = @"Hey Chandler,
I just wanted to let you know that Monica and I were going to go play some paintball, you in?
-- Joey"
};
using (var client = new SmtpClient ()) {
// For demo-purposes, accept all SSL certificates (in case the server supports STARTTLS)
client.ServerCertificateValidationCallback = (s,c,h,e) => true;
client.Connect ("smtp.friends.com", 587, false);
// Note: only needed if the SMTP server requires authentication
client.Authenticate ("joey", "password");
client.Send (message);
client.Disconnect (true);
}
