问题是：我想在电子邮件发送成功时显示成功消息框。请帮忙

Answer 1

你试过MessageBox.Show ??

Answer 2

根据您的代码以及您在公共论坛上发布实际凭据的事实，我假设您只需要一个同步解决方案，并希望在（阻止）调用MyServer.Send(); <后显示一个消息框/ p>

将您的发送封装在try/catch块中：

// The program will attempt to send a message
try
{
    MySever.Send(MyMsg);
    MessageBox.Show("Message sent successfully");
}
catch (Exception ex)
{
    // Whoops there was an error sending the message, better tell the user what happened.
    MessageBox.Show(String.Format("Message Failed To send because: {0}", ex.message);
}

如果这不起作用，那么您需要在问题中添加一些上下文，例如您看到的任何错误或异常。

执行此操作的“正确”方法是执行MyServer.SendAsync(MyMsg)，然后让回调听取SendCompleted类提供给您的SMTPClient事件：
