重新发送确认电子邮件（如果未发送给客户）

Question

我有用于向新帐户注册发送确认电子邮件的代码。我想要页面上的按钮，以便客户在以前未收到他们的电子邮件时，可以使用该按钮将电子邮件确认链接重新发送到他们的电子邮件

还没有尝试过，我是.NET MVC的新手，它基于NopCommerce。

public class EmailService : IIdentityMessageService
{
    public Task SendAsync(IdentityMessage message)
    {

        // Plug in your email service here to send an email.
        string text = message.Body;
        string html = message.Body;
        //do whatever you want to the message        
        MailMessage msg = new MailMessage();
        msg.From = new MailAddress("support@easypostagelabels.com");
        msg.To.Add(new MailAddress(message.Destination));
        msg.Subject = message.Subject;
        msg.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(text, null, MediaTypeNames.Text.Plain));
        msg.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(html, null, MediaTypeNames.Text.Html));

        SmtpClient smtpClient = new SmtpClient("easypostagelabels.com", 25);// Convert.ToInt32(25));//587
        smtpClient.EnableSsl = false;
        System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("support@easypostagelabels.com", "Admin@1234");
        smtpClient.Credentials = credentials;
        try
        {

            smtpClient.Send(msg);
            string texterr = "success";
            // WriteAllText creates a file, writes the specified string to the file,
            // and then closes the file.    You do NOT need to call Flush() or Close().
            System.IO.File.WriteAllText(HttpContext.Current.Server.MapPath("/Content/error.txt"), texterr);
        }
        catch (System.Net.Mail.SmtpException E)
        {
            string texterr = E.Message;
            // WriteAllText creates a file, writes the specified string to the file,
            // and then closes the file.    You do NOT need to call Flush() or Close().
            System.IO.File.WriteAllText(HttpContext.Current.Server.MapPath("/Content/error.txt"), texterr);
        }
        return Task.FromResult(0);
    }
}
