Answer 1

您的问题是您根本没有使用 SendGrid ，而是使用了SmtpClient

如果要使用 SendGrid ，则将需要下载nuget并编写 SendGrid 代码，而您所需要的都不是。

请仔细阅读以下示例和nuget包

Answer 2

您应该使用SendGridClient类通过SendGrid发送邮件，然后将apiKey作为参数传递给它

        static async Task Execute()
        {
            var apiKey = // your key
            var client = new SendGridClient(apiKey);
            var msg = new SendGridMessage()
            {
                From = new EmailAddress("test@example.com", "DX Team"),
                Subject = "Hello World from the SendGrid CSharp SDK!",
                PlainTextContent = "Hello, Email!",
                HtmlContent = "<strong>Hello, Email!</strong>"
            };
            msg.AddTo(new EmailAddress("test@example.com", "Test User"));
            var response = await client.SendEmailAsync(msg);
        }
