推荐答案

这是初学者在尝试发送电子邮件时必须面对的最基本错误。最常见的问题是：



1.主机名或协议不正确 - 这在您的代码中似乎不是问题。

2.用户名密码错误。必须检查哪一方。



重新检查这些并再试一次。基本上，您应该尝试使用已经过多次测试的工作代码示例。例如，尝试我编写的以下代码，

This the most basic error that beginners have to face while trying to send the email. The most common issues are:

1. Hostname or protocol not correct — which doesn't seem to be an issue over there in your code.
2. Username password error. Which must be checked on your side.

Re-check these and try again. Basically, you should try using a working code sample, that has been tested multiple times. For example, try the following code that I wrote,

// You should use a using statement
using (SmtpClient client = new SmtpClient("<smtp-server-address>", 25))
{
   // Configure the client
   client.EnableSsl = true;
   client.Credentials = new NetworkCredential("<username>", "<password>");
   // client.UseDefaultCredentials = true;

   // A client has been created, now you need to create a MailMessage object
   MailMessage message = new MailMessage(
                            "[e-mail]", // From field
                            "[e-mail]", // Recipient field
                            "Hello", // Subject of the email message
                            "World!" // Email message body
                         );

   // Send the message
   client.Send(message);

   /* 
    * Since I was using Console app, that is why I am able to use the Console
    * object, your framework would have different ones. 
    * There is actually no need for these following lines, you can ignore them
    * if you want to. SMTP protocol would still send the email of yours. */
    
   // Print a notification message
   Console.WriteLine("Email has been sent.");
   // Just for the sake of pausing the application
   Console.Read();
}
