SendGrid在发送电子邮件时抛出InvalidApiRequestException.

SendGrid is throwing an InvalidApiRequestException when sending an email.

我正在使用以下代码:

public Task SendEmailAsync(string email, string subject, string message) { // Plug in your email service here to send an email. var myMessage = new SendGrid.SendGridMessage(); myMessage.AddTo(email); myMessage.From = new MailAddress("varshney@shobhit", "Shobhit", System.Text.Encoding.Default); myMessage.Subject = subject; myMessage.Text = message; myMessage.Html = message; var credentials = new NetworkCredential( Options.SendGridUser, Options.SendGridKey); // Create a Web transport for sending email. var transportWeb = new SendGrid.Web(credentials); // Send the email. if (transportWeb != null) { return transportWeb.DeliverAsync(myMessage); } else { return Task.FromResult(0); } }

推荐答案

确保使用的是SendGrid C#库6.3.x或更高版本.以前的库版本中有一个错误.

Make sure you are using SendGrid C# Library version 6.3.x or later. There was a bug in the previous library version.
