Question

我正在尝试运行此代码，但出现以下异常：发送邮件失败。

我的代码如下：

try
        {
            MailMessage mail = new MailMessage("from@gmail.com", "to@gmail.com");
            SmtpClient client = new SmtpClient
            {
                Port = 465,
                UseDefaultCredentials = false,
                Host = "smtp.gmail.com",
                EnableSsl = true,
                Credentials = new NetworkCredential("from@gmail.com", "xxxxxxx")
            };
            mail.Subject = "Hello";
            mail.Body = "This is test Message";
            client.Send(mail);
        }
        catch (Exception _ex)
        {
            Debug.Write(_ex.Message);
        }

即使我打开了“安全性较低的应用程序”

假设您的凭据是正确的，则初始化可能有误。

这是我的摘录

            SmtpClient client = new SmtpClient();
            MailMessage mailMessage = new MailMessage();

            client = new SmtpClient("smtp.xxx.com", port_number);
            client.Credentials = new NetworkCredential("xxx@xxx.xx", "xxx");
            client.EnableSsl = true;
            mailMessage.From = new MailAddress("from@xxx.co", "xx xx", Encoding.UTF8);
            mailMessage.Subject = $"mail subject";

            mailMessage.Body = emailHtml;
            mailMessage.IsBodyHtml = true;

            mailMessage.To.Add("to@xx.com");
            mailMessage.Bcc.Add("bcc@xx.com");
            await client.SendMailAsync(mailMessage);

邮件发送失败。在Asp.net
