指定的字符串不是电子邮件地址所需的格式，不知道有什么问题？

Question

我知道这个问题已经存在，但我阅读了所有问题，但没有找到答案。这是我的 SendEmail 方法。

   public bool SendEmail(PostEmail postEmail)
{
  if (string.IsNullOrEmpty(postEmail.emailTo))
  {
    return false;
  }

  using (SmtpClient smtpClient = new SmtpClient())
  {
    using (MailMessage message = new MailMessage())
    {
      message.Subject = postEmail.subject == null ? "" : postEmail.subject;
      message.Body = postEmail.body == null ? "" : postEmail.body;
      message.IsBodyHtml = postEmail.isBodyHtml;
      message.To.Add(new MailAddress(postEmail.emailTo));

      try
      {
        smtpClient.Send(message);
        return true;
      }
      catch (Exception exception)
      {
        //Log the exception to DB
        throw new FaultException(exception.Message);
      }
    }
  }

我遇到了这个错误

The specified string is not in the form required for an e-mail address

我不知道哪里出了问题。请任何帮助？

Answer 1

在线打个断点

message.To.Add(new MailAddress(postEmail.emailTo));

并且当您 运行 代码时调试器命中该行 检查电子邮件地址的值 postEmail.emailTo

它的格式很可能是错误的，这就是生成的格式 错误。

Answer 2

这是定义客户端和发送电子邮件的正确方法。定义的完整结构是错误的，它不仅仅是关于 emailTo string

命名空间App.MYEmailApp.Service {

public class 电子邮件服务：IEmail服务 {

public void SendEmail(PostEmail postEmail)
{

  MailAddress from = new MailAddress(postEmail.emailFrom, postEmail.emailFromName);
  MailAddress to = new MailAddress(postEmail.emailTo, postEmail.emailToName);
  MailMessage message = new MailMessage(from, to);
  message.Subject = postEmail.subject;
  message.Body = postEmail.body;
  MailAddress bcc = new MailAddress("xxxx@gmail.com");
  message.Bcc.Add(bcc);
  SmtpClient client = new SmtpClient();
  //client.UseDefaultCredentials = false;
  //client.Credentials.GetCredential("smtp.xxxx.com", 587, "server requires authentication");
  Console.WriteLine("Sending an e-mail message to {0} and {1}.", to.DisplayName, message.Bcc.ToString());
  try
  {
    client.Send(message);
  }
  catch (Exception ex)
  {
    Console.WriteLine("Exception caught in CreateBccTestMessage(): {0}",
                ex.ToString());
  }




}

}

public class 邮箱 {

public string emailTo;
public string emailToName;
public string subject;
public string body;
public string emailFrom;
public string emailFromName;
public bool isBodyHtml;

}

}
