如何在C＃中发送HTML内容以发送网格电子邮件

如何解决如何在C＃中发送HTML内容以发送网格电子邮件

我尝试使用c＃库通过发送网格发送电子邮件。以下是我的代码

var apiKey ="xxxxxxxxx";//dumy
var client = new SendGridClient(apiKey);
var from = new EmailAddress("asdasd@gmail.com","Example User");
var subject = "Sending with SendGrid is Fun";
var to = new EmailAddress("asdasd2@gmail.com","Example User");
var plainTextContent = "and easy to do anywhere,even with C#";
var ww = "www.google.com";
var email = "asdasd2@gmail.com"

var htmlContent = string.Format(@"<strong>Hi{0}</strong>
<p>You are invited to  signup in  portal.You can signup using below signup button</p>
<p><a href={1}>Visit W3Schools.com!</a></p>",email,ww);
var msg = MailHelper.CreateSingleEmail(from,to,subject,plainTextContent,htmlContent);     
var response =  client.SendEmailAsync(msg).GetAwaiter().GetResult();

我将html内容转换为字符串并执行代码。但是没有收到电子邮件。我的代码有什么问题吗？。当我收到htmlContent时收到电子邮件
