如何在发送邮件时将gridview值作为附件包含

Question

我想添加第2列[DRAFT PATH]中的文件名，并在发送邮件时作为附件包含。我如何将这些详细信息作为附件添加，并且我需要在正文中包含文本信息。

Ex-在给定的链接中https://imageshack.com/i/f0YGXzlvj您可以看到Draft path中只有一个文件。所以我需要从文件夹中附加那个文件。。作为附件。。此外，我需要包括

[邮件正文]

     Total number of files :    Draft path files
     File1:- file name of `draft path` file

正如你所看到的，其余单元格都是空的。。所以没必要在正文中提及。。

如果有更多的文件，那么我需要根据它来做

代码片段：-

 private void button2_Click(object sender, EventArgs e)
    {
        MessageBox.Show("Sending Mail. Click Ok!!!", "Mail!!!.");
        string smtpserver = ini.ReadValue("bmail", "smtpserver");
        string email_From = ini.ReadValue("bmail", "email_From");
        string email_Recipient = ini.ReadValue("bmail", "email_Recipient");
        string email_Subject = ini.ReadValue("bmail", "email_Subject");
        string email_Body = ini.ReadValue("bmail", "email_Body");

            try
            {
                new SmtpClient(smtpserver, 25).Send(email_From,
                                      email_Recipient,
                                      email_Subject,
                                      email_Body);
                MessageBox.Show("Email Successfully Sent!!!", "Mail!!!.");
                Environment.Exit(0);
            }
            catch (System.Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

我该怎么做。。请帮帮我。

您可以通过附件发送这样的邮件。

SmtpClient smtp = new SmtpClient();
MailMessage msg = new MailMessage();
msg.From = new MailAddress("[e-mail]", "Stacy Kebler");
smtp.Host = "smtp.gmail.com";
smtp.Port = 465;  //set the default smtp port of email provider. you can avoid it if you don't know
smtp.Credentials = new System.Net.NetworkCredential("[e-mail]", "stacy123");
smtp.EnableSsl = true; //Set this to true if the email provider is using SSL encryption 
smtp.Timeout = 10000; //Set the timeout to 10 second
msg.To.Add(new MailAddress("[e-mail]","Mr. ABC"));
msg.IsBodyHtml = true; //if the content of body is in HTML format then set it to true.

msg.Subject = "This is a sample message";
StringBuilder sbBody = new StringBuilder();
sbBody.Append("This is the Sample Email <br><br>");
for (int i = 0; i < dataGridView.Rows.Count; i++)
{
    if (dataGridView.Rows[i].Cells["DRAFT_PATH"].Value != null && 
        System.IO.File.Exists(dataGridView.Rows[i].Cells["DRAFT_PATH"].Value.ToString()))
    {
        string path = dataGridView.Rows[i].Cells["DRAFT_PATH"].Value.ToString();
        sbBody.AppendFormat("File {0}:{1}<br>", i + 1, Path.GetFileNameWithoutExtension(path))
        msg.Attachments.Add(new Attachment(path));
    }
}
msg.Body = sbBody.ToString();

smtp.Send(msg);

如果您不想在发送电子邮件时阻止当前线程。然后可以使用异步方法发送邮件。这不会阻止电子邮件发送过程。您只需要使用SendAsync()方法而不是Send()

smtp.SendAsync(msg, "Test Message");

其中第二个参数用于该进程的令牌。如果你想在发送电子邮件后做任何进一步的处理，并且你也发送了多封电子邮件，那么token将帮助你确定具体的邮件处理。

例如：如果你同时发送两封邮件

smtp1.SendAsync(msg1, "Test Message 1");
smtp1.SendCompleted += new SendCompletedEventHandler(this.SendCompletedCallback);

smtp2.SendAsync(msg2, "Test Message 2");
smtp2.SendCompleted += new SendCompletedEventHandler(this.SendCompletedCallback);

private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e)
{
    // Get the unique identifier for this asynchronous operation.
    String token = (string) e.UserState;
    if (token == "Test Message 1")
        //This is the First email status
    else if (token == "Test Message 2")
        //This is the second email status
}

如果你想在不分配凭据的情况下发送电子邮件，那么你必须有一个电子邮件服务器的电子邮件网关。

SmtpClient msg = new SmtpClient("username.gateway.com");
