我创建了一个程序,试图在网站上发布一个字符串,我收到此错误:

"服务器提交了协议违规.Section = ResponseStatusLine"

在这行代码之后:

gResponse = (HttpWebResponse)gRequest.GetResponse(); 

我该如何解决这个异常？

我在没有对代码进行任何更改的情况下收到此错误。以前，它运行良好。

Depth: 0<br />Exception Type:System.Net.Mail.SmtpException<br />Exception: The server committed a protocol violation The server response was: <br />Inner Source: System<br />Stack Trace:    at System.Net.Mail.SendMailAsyncResult.End(IAsyncResult result)
   at System.Net.Mail.SmtpClient.SendMailCallback(IAsyncResult result)

我的代码：

private async Task SmtpClientSendMail(MailMessage mailMessage)
{
    using (SmtpClient smtpClient = new SmtpClient("smtp.office365.com"))
    {
        try
        {
            smtpClient.UseDefaultCredentials = false;
            smtpClient.Port = 587;
            smtpClient.Credentials = new System.Net.NetworkCredential(emailUserNameCredentials, emailPasswordCredentials);
            smtpClient.EnableSsl = true;
            smtpClient.Timeout = 200000;
            await smtpClient.SendMailAsync(mailMessage);
        }
        catch (Exception ex)
        {

        }
    }
}

正如 System.Net.WebException 中所建议的：服务器违反了协议

我已将其直接添加到我的 App.config 部分中：

<system.net>
  <settings> …
