        DialogResult rlst = MessageBox.Show("Do you want to send this email without a subject", "Forward Applicant", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
        if (rlst == DialogResult.No)
        {
            tbSubject.Focus();
            return;
        }

    if (rtbMsg.Text == "")
    {
        DialogResult rlst = MessageBox.Show("Do you want to send an empty email", "Forward Applicant", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
        if (rlst == DialogResult.No)
        {
            rtbMsg.Focus();
            return;
        }
    }

    validator.IsAlphaNumeric(rtbMsg.Text);

    Mail.To = cbTo.Text;
    Mail.CC = cbCopy.Text;
    Mail.Subject = tbSubject.Text;
    Mail.Body = rtbMsg.Text;

    if (tbAttchmnt.Text != "")
    {
        Mail.Attachments.Add(tbAttchmnt.Text, (int)OutLook.OlAttachmentType.olByValue, (int)Mail.Body.Length + 1, "Attached File");
    }

    Mail.Send();
    MessageBox.Show("Applicant has been forwarded", "Forward Applicant", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch (ArgumentException)
{
    DialogResult rslt = MessageBox.Show("Please a valid email address", "Email Problem", MessageBoxButtons.OK, MessageBoxIcon.Error);
    if (rslt == DialogResult.OK)
    {
        //cbTo.Text = "";
        cbTo.Focus();
    }
}


catch (FormatException)
{
    DialogResult rslt = MessageBox.Show("Please enter only alphanumeric characters in subject and message body", "Email Problem", MessageBoxButtons.OK, MessageBoxIcon.Error);
    if (rslt == DialogResult.OK)
    {
        tbSubject.Focus();
    }
}
catch (Exception ex)
{
    MessageBox.Show(ex.ToString());
}

推荐答案

如果您正在使用Outlook(通过互操作)，则Outlook实例必须正在运行(或由互操作启动).

如果要发送不带Outlook的电子邮件，则可以使用基于SMTP的发送.请参阅: http://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.aspx [ ^ ]

Hi,

If you''re utilizing Outlook (via Interop) an instance of outlook must be running (or started by interop).

If you want to send an email without outlook, you could use SMTP based sending. See: http://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.aspx[^]

我面临的问题是，我需要先打开Outlook才能发送邮件.无论ms Outlook是否正在运行，有没有一种我可以发送邮件的方式
AFAIK，答案是否定的.要运行Outlook，必须先运行它.如果不是这样，将自动发生的第一步是打开Outlook，然后使用它的功能.

The problem I am facing is that, i need to have outlook open before the mails can be sent. Is there a way i can send the mails regardless of whether ms outlook is running or not
AFAIK, the answer is No. Outlook has to be running in order to do it. In case it is not, first step would that would happen automatically is to open the Outlook and then use it''s functionality.
