我正在做所有事情，如 sendgrid 的文档中所示

    var client = new SendGridClient(apiKey);
    var from = new EmailAddress("[e-mail]", "Example User");
    var subject = "Sending with SendGrid is Fun";
    var to = new EmailAddress("[e-mail]", "Example User");
    var plainTextContent = "and easy to do anywhere, even with C#";
    var htmlContent = "<strong>and easy to do anywhere, even with C#</strong>";
    var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
    var response = await client.SendEmailAsync(msg);
    Console.WriteLine(response.StatusCode);
