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?

这是发送邮件的附件。简单而简短。

using System.Net;
using System.Net.Mail;
public void email_send()
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("your mail@gmail.com");
mail.To.Add("to_mail@gmail.com");
mail.Subject = "Test Mail - 1";
mail.Body = "mail with attachment";
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment("c:/textfile.txt");
mail.Attachments.Add(attachment);
SmtpServer.Port = 587;
SmtpServer.Credentials = new System.Net.NetworkCredential("your mail@gmail.com", "your password");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
}

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);
}
为了避免Gmail的安全问题,你应该先从Gmail的设置中生成一个应用程序密码,即使你使用两步验证,你也可以使用这个密码而不是真实密码来发送电子邮件。
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
从另一个答案复制,上述方法工作,但gmail总是替换“从”和“回复”电子邮件与实际发送gmail帐户。然而,显然有一种方法:
http://karmic-development.blogspot.in/2013/10/send-email-from-aspnet-using-gmail-as.html
“3。在帐户选项卡,点击链接“添加另一个电子邮件地址你自己的”,然后验证它
或者可能是这个
更新3:读者德里克·贝内特说:“解决办法是进入你的gmail设置:账户,并“默认”一个gmail账户以外的账户。这将导致gmail用默认帐户的电子邮件地址重写From字段。”
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>
