发送电子邮件 - 我哪里出错了

Question

我正在尝试发送电子邮件，每次调用此方法并尝试发送它时，都会抛出"发送邮件失败"的错误。它不是很具有描述性，我不确定这甚至失败了哪一点，因为它遍历了所有代码并且似乎还可以。

代码：

public void SendEmail()
{
    private string localhost = System.Net.Dns.GetHostName();
    System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();
    msg.To.Add(strUserEmail);
    //determine if the email sent was successful
    if (blnFlag == true)
    {
        msg.Subject = "File Move was successful";
    }
    else
    {
        msg.Subject = "File Move";
    }
    msg.From = new System.Net.Mail.MailAddress(GlobalVars.strFromEmail);
    msg.Body = strMessage;
    SmtpClient client = new SmtpClient(localhost);
    client.Send(msg);
}

Answer 1

 client.EnableSsl = true;
 NetworkCredential crend = new NetworkCredential("SenderMailAddress","SenderPassword" );
 client.Credentials = crend;

并尝试捕获发送方法 - 这只是常见的选择）
