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);
}

来源:在ASP发送电子邮件。净c#
下面是一个使用c#发送邮件的示例工作代码,在下面的例子中,我使用谷歌的smtp服务器。
代码是相当不言自明的,替换电子邮件和密码与您的电子邮件和密码值。
public void SendEmail(string address, string subject, string message)
{
string email = "yrshaikh.mail@gmail.com";
string password = "put-your-GMAIL-password-here";
var loginInfo = new NetworkCredential(email, password);
var msg = new MailMessage();
var smtpClient = new SmtpClient("smtp.gmail.com", 587);
msg.From = new MailAddress(email);
msg.To.Add(new MailAddress(address));
msg.Subject = subject;
msg.Body = message;
msg.IsBodyHtml = true;
smtpClient.EnableSsl = true;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = loginInfo;
smtpClient.Send(msg);
}
编辑2022 从2022年5月30日起,谷歌将不再支持仅使用用户名和密码登录谷歌账户的第三方应用程序或设备。 但是你仍然可以通过你的gmail账户发送电子邮件。
访问https://myaccount.google.com/security,打开两步验证。如有需要,请电话确认。 点击“应用程序密码”,就在“2步验证”勾的下方。 请求邮件应用程序的新密码。
现在只需使用这个密码,而不是原来的一个为您的帐户!
public static void SendMail2Step(string SMTPServer, int SMTP_Port, string From, string Password, string To, string Subject, string Body, string[] FileNames) {
var smtpClient = new SmtpClient(SMTPServer, SMTP_Port) {
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
EnableSsl = true
};
smtpClient.Credentials = new NetworkCredential(From, Password); //Use the new password, generated from google!
var message = new System.Net.Mail.MailMessage(new System.Net.Mail.MailAddress(From, "SendMail2Step"), new System.Net.Mail.MailAddress(To, To));
smtpClient.Send(message);
}
像这样使用:
SendMail2Step("smtp.gmail.com", 587, "youraccount@gmail.com",
"yjkjcipfdfkytgqv",//This will be generated by google, copy it here.
"recipient@barcodes.bg", "test message subject", "Test message body ...", null);
对于其他答案工作“从服务器”首先打开访问gmail帐户不太安全的应用程序。这将在2022年5月30日被弃用
看来最近谷歌改变了安全策略。评分最高的答案不再有效,直到您更改您的帐户设置如下所述:https://support.google.com/accounts/answer/6010255?hl=en-GB 2016年3月,谷歌再次更改设置地点!
我也遇到了同样的问题,但通过gmail的安全设置和允许不太安全的应用程序解决了。 Domenic & Donny的代码有效,但前提是你启用了该设置
如果您已登录(到谷歌),您可以按照此链接并切换“打开”以“访问不太安全的应用程序”
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>
