推荐答案

您不太可能在此地址上启动并运行SMTP服务器，这是本地的。你需要使用一些外部服务器;并且您很可能需要在该服务器上注册并使用身份验证。

This is very unlikely that you have an SMTP server up and running on this address, which is local. You need to use some external server; and it also very likely that you will need to be registered with that server and use authentication.

Dim mail As New MailMessage()
        Dim SmtpServer As New SmtpClient("smtp.gmail.com")
        mail.From = New MailAddress(txtid.Text)
        mail.[To].Add("Email Id to [e-mail]")
        mail.Subject = txtsub.Text
        mail.Body = txtmess.Text
        mail.Attachments.Add(New Attachment(OpenFileDialog1.FileName))
        SmtpServer.Port = 587
        SmtpServer.Credentials = New System.Net.NetworkCredential(txtid.Text, txtpass.Text)
        SmtpServer.EnableSsl = True
        SmtpServer.Send(mail)
        mail.From = New MailAddress(txtid.Text)
        MsgBox("E-mail Has Been Send Successfully !")

在vb.net中发送电子邮件非常简单，请查看此代码或直接使用。

如果你是发送附件，那么使用openfiledialogbox控件。

Its very simple to send email in vb.net please check this code or use directly.
If you are send attachment then use the openfiledialogbox control.

看看使用或不使用附件在C＃中发送电子邮件：通用例程。 [ ^ ]
