如何在 vb.net 中发送 gmail 电子邮件? [英] How do I send a gmail email in vb.net?
问题描述
我想发送一封电子邮件，但它给了我一个错误.
I want to send an email, but it gives me an error.
我有这个代码:
Sub sendMail(ByVal title As String, ByVal content As String)
Dim SmtpServer As New SmtpClient("smtp.gmail.com", 25)
SmtpServer.Credentials = New Net.NetworkCredential("name@gmail.com", "password")
Dim mail As New MailMessage("name@gmail.com", "name@gmail.com", title, content)
SmtpServer.Send(mail)
End Sub
我有一个 try catch 尝试调用此方法，但它不起作用，所以 catch 运行并且我得到了异常:System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was未认证.服务器响应是: 5.7.0 必须首先发出 STARTTLS 命令.b6sm3176487lae.0 - gsmtp 为什么会出现此错误?以及如何解决?

推荐答案
Gmail 在端口 465 上使用 SMTP over SSL.
Gmail uses SMTP over SSL on port 465.
尝试做:
Dim SmtpServer As New SmtpClient("smtp.gmail.com", 465)
...
SmtpServer.EnableSsl = True
...
