我想用我的Gmail帐户发送电子邮件,而不是依靠我的主机发送电子邮件。这些邮件是发给我在节目中演出的乐队的个性化邮件。
有可能做到吗?

上面的答案不管用。必须设置DeliveryMethod = SmtpDeliveryMethod。网络,否则将返回“客户端未经过身份验证”错误。此外,暂停总是一个好主意。
修改后的代码:
using System.Net.Mail;
using System.Net;
var fromAddress = new MailAddress("from@gmail.com", "From Name");
var toAddress = new MailAddress("to@yahoo.com", "To Name");
const string fromPassword = "password";
const string subject = "test";
const string body = "Hey now!!";
var smtp = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
Timeout = 20000
};
using (var message = new MailMessage(fromAddress, toAddress)
{
Subject = subject,
Body = body
})
{
smtp.Send(message);
}

下面是一个从web.config发送邮件和获取凭证的方法:
public static string SendEmail(string To, string Subject, string Msg, bool bodyHtml = false, bool test = false, Stream AttachmentStream = null, string AttachmentType = null, string AttachmentFileName = null)
{
try
{
System.Net.Mail.MailMessage newMsg = new System.Net.Mail.MailMessage(System.Configuration.ConfigurationManager.AppSettings["mailCfg"], To, Subject, Msg);
newMsg.BodyEncoding = System.Text.Encoding.UTF8;
newMsg.HeadersEncoding = System.Text.Encoding.UTF8;
newMsg.SubjectEncoding = System.Text.Encoding.UTF8;
System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient();
if (AttachmentStream != null && AttachmentType != null && AttachmentFileName != null)
{
System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment(AttachmentStream, AttachmentFileName);
System.Net.Mime.ContentDisposition disposition = attachment.ContentDisposition;
disposition.FileName = AttachmentFileName;
disposition.DispositionType = System.Net.Mime.DispositionTypeNames.Attachment;
newMsg.Attachments.Add(attachment);
}
if (test)
{
smtpClient.PickupDirectoryLocation = "C:\\TestEmail";
smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.SpecifiedPickupDirectory;
}
else
{
//smtpClient.EnableSsl = true;
}
newMsg.IsBodyHtml = bodyHtml;
smtpClient.Send(newMsg);
return SENT_OK;
}
catch (Exception ex)
{
return "Error: " + ex.Message
+ "<br/><br/>Inner Exception: "
+ ex.InnerException;
}
}
以及web.config中相应的部分:
<appSettings>
<add key="mailCfg" value="yourmail@example.com"/>
</appSettings>
<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="yourmail@example.com">
<network defaultCredentials="false" host="mail.exapmple.com" userName="yourmail@example.com" password="your_password" port="25"/>
</smtp>
</mailSettings>
</system.net>
在谷歌更新后,这是使用c#或。net发送电子邮件的有效方法。
using System;
using System.Net;
using System.Net.Mail;
namespace EmailApp
{
internal class Program
{
public static void Main(string[] args)
{
String SendMailFrom = "Sender Email";
String SendMailTo = "Reciever Email";
String SendMailSubject = "Email Subject";
String SendMailBody = "Email Body";
try
{
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com",587);
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
MailMessage email = new MailMessage();
// START
email.From = new MailAddress(SendMailFrom);
email.To.Add(SendMailTo);
email.CC.Add(SendMailFrom);
email.Subject = SendMailSubject;
email.Body = SendMailBody;
//END
SmtpServer.Timeout = 5000;
SmtpServer.EnableSsl = true;
SmtpServer.UseDefaultCredentials = false;
SmtpServer.Credentials = new NetworkCredential(SendMailFrom, "Google App Password");
SmtpServer.Send(email);
Console.WriteLine("Email Successfully Sent");
Console.ReadKey();
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
Console.ReadKey();
}
}
}
}
要创建应用程序密码,您可以按照这篇文章: https://www.techaeblogs.live/2022/06/how-to-send-email-using-gmail.html
谷歌已经从我们的谷歌帐户中删除了不太安全的应用程序设置,这意味着我们不能再使用我们实际的谷歌密码从SMTP服务器发送电子邮件。我们需要使用Xoauth2并授权用户,或者在启用了2fa的帐户上创建一个应用程序密码。
一旦创建了应用程序密码,就可以用来代替你的标准gmail密码。
class Program
{
private const string To = "test@test.com";
private const string From = "test@test.com";
private const string GoogleAppPassword = "XXXXXXXX";
private const string Subject = "Test email";
private const string Body = "<h1>Hello</h1>";
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
var smtpClient = new SmtpClient("smtp.gmail.com")
{
Port = 587,
Credentials = new NetworkCredential(From , GoogleAppPassword),
EnableSsl = true,
};
var mailMessage = new MailMessage
{
From = new MailAddress(From),
Subject = Subject,
Body = Body,
IsBodyHtml = true,
};
mailMessage.To.Add(To);
smtpClient.Send(mailMessage);
}
}
快速修复SMTP用户名和密码不接受错误
using System;
using System.Net;
using System.Net.Mail;
namespace SendMailViaGmail
{
class Program
{
static void Main(string[] args)
{
//Specify senders gmail address
string SendersAddress = "Sendersaddress@gmail.com";
//Specify The Address You want to sent Email To(can be any valid email address)
string ReceiversAddress = "ReceiversAddress@yahoo.com";
//Specify The password of gmial account u are using to sent mail(pw of sender@gmail.com)
const string SendersPassword = "Password";
//Write the subject of ur mail
const string subject = "Testing";
//Write the contents of your mail
const string body = "Hi This Is my Mail From Gmail";
try
{
//we will use Smtp client which allows us to send email using SMTP Protocol
//i have specified the properties of SmtpClient smtp within{}
//gmails smtp server name is smtp.gmail.com and port number is 587
SmtpClient smtp = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
Credentials = new NetworkCredential(SendersAddress, SendersPassword),
Timeout = 3000
};
//MailMessage represents a mail message
//it is 4 parameters(From,TO,subject,body)
MailMessage message = new MailMessage(SendersAddress, ReceiversAddress, subject, body);
/*WE use smtp sever we specified above to send the message(MailMessage message)*/
smtp.Send(message);
Console.WriteLine("Message Sent Successfully");
Console.ReadKey();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
Console.ReadKey();
}
}
}
}
一定要使用System.Net。邮件,而不是已弃用的System.Web.Mail。使用System.Web.Mail进行SSL是一堆拙劣的扩展。
using System.Net;
using System.Net.Mail;
var fromAddress = new MailAddress("from@gmail.com", "From Name");
var toAddress = new MailAddress("to@example.com", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";
var smtp = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
};
using (var message = new MailMessage(fromAddress, toAddress)
{
Subject = subject,
Body = body
})
{
smtp.Send(message);
}
此外,转到谷歌帐户>安全页面,并查看登录谷歌> 2步验证设置。
如果启用了,那么您必须生成一个密码,允许. net绕过2步验证。点击“Signing in To谷歌> App passwords”,选择App = Mail, device = Windows Computer,最后生成密码。在fromPassword常量中使用生成的密码,而不是标准的Gmail密码。 如果它被禁用,那么你必须打开Less secure app access,这是不推荐的!所以最好启用两步验证。
