推荐答案

对于SMTP，声明消息的以下格式对我来说运行正常：

For SMTP, the following format to declare the message works fine for me:

MailMessage mail = new MailMessage();
// add message 'from' field
mail.From = new MailAddress("[e-mail]");
// add recipient 'to' field
mail.To.Add("[e-mail]");
// append the message subject
mail.Subject = "my mail subject";
// append the message body
mail.Body = "my message body";

smtp.Send(mail);

您好，首先您在asp.net页面中使用过代码，但无论何时您参考，它都使用控件而不是asp.net页面



您的参考代码工作正常..我看看它..



谢谢



快乐编码......
