标签：Sendgrid System.ArgumentException：Unknown element：html

我刚刚将以下软件包更新为最新版本：

a)SendGrid.SmtpApi更新到1.3.1

b)SendGrid更新到6.0

突然之间不再有WebTransport.Deliver方法了-没问题,我已经切换到DeliverAsync方法,但是现在我遇到一个非常奇怪的错误,该错误应该在两年前修复：

System.ArgumentException: Unknown element: html

这是您可能感兴趣的堆栈跟踪的一部分：

System.ArgumentException: Unknown element: html

Stream stream)

这也是我的电子邮件发送代码的样子：

SendGridMessage emailMessage = new SendGridMessage();
emailMessage.AddTo(user.CompleteRegistrationModel.UserEmailAddress);
emailMessage.From = new MailAddress(ConfigurationHelper.EmailSenderAddress, ConfigurationHelper.EmailSenderName);
emailMessage.EnableTemplateEngine(ConfigurationHelper.ConfirmationEmailTemplateId);
emailMessage.AddSubstitution("-urlaplicatie-",
                new List<string>()
                {
                    String.Format("{2}{0}{1}", user.CompleteRegistrationModel.CompanyUrlPrefix,
                        ConfigurationHelper.DomainSuffix, ConfigurationHelper.ApplicationAccessProtocol)
                });
            emailMessage.AddSubstitution("-username-",
                new List<string>() {user.CompleteRegistrationModel.UserEmailAddress});
            emailMessage.AddSubstitution("-confirmationurl-",
                new List<string>() {user.CompleteRegistrationModel.UserEmailAddressConfirmationCompleteUrl});

            emailMessage.Subject = String.Format("{0}{1}", user.CompleteRegistrationModel.CompanyUrlPrefix,
                ConfigurationHelper.DomainSuffix);
            emailMessage.Text = " ";
            emailMessage.Html = " ";

            Web webTransport =
                new Web(new NetworkCredential(ConfigurationHelper.SendgridUsername,
                    ConfigurationHelper.SendgridPassword));

            try
            {
                await webTransport.DeliverAsync(emailMessage);
            }
            catch (InvalidApiRequestException exception)
            {
                Elmah.ErrorSignal.FromCurrentContext().Raise(exception);
            }

有人可以告诉我发生了什么事吗？

谢谢,
伊夫丁
