C# 使用c从hotmail发送邮件有时会失败#
我有c#代码发送邮件。该代码在gmail、yahoo配置中运行良好。但对于hotmail，有时会发送邮件，有时不会发送邮件。我观察到雅虎邮件的响应时间比gmail要好。但与雅虎、gmail相比，hotmail的响应非常差 原因是什么？如何配置hotmail以获得良好的响应 这是我发送邮件的代码：C# 使用c从hotmail发送邮件有时会失败#,c#,email,C#,Email,我有c#代码发送邮件。该代码在gmail、yahoo配置中运行良好。但对于hotmail，有时会发送邮件，有时不会发送邮件。我观察到雅虎邮件的响应时间比gmail要好。但与雅虎、gmail相比，hotmail的响应非常差 原因是什么？如何配置hotmail以获得良好的响应 这是我发送邮件的代码： private void button2_Click(object sender, EventArgs e) { SmtpClient client = new SmtpC

如果您尝试使用上述代码发送电子邮件，它显然无法发送，我不知道您使用
Ping SmtpClient client = new SmtpClient();
MailMessage message = new MailMessage();
message.To.Add("user_name");
message.From = new MailAddress("user_name");
message.Subject = "Email Confirmation";
message.BodyEncoding = Encoding.UTF8;
message.SubjectEncoding = Encoding.UTF8;
client.Port = 587;
client.Host = "smtp.live.com";
NetworkCredential nc = new NetworkCredential("user_name", "password");
string mail_server = "smtp.live.com";
if (mail_server == "smtp.gmail.com" || mail_server == "smtp.live.com")
{
client.EnableSsl = true;
}
client.UseDefaultCredentials = false;
client.Credentials = nc;
try
{
client.Send(message);
}
catch (SmtpException exception)
{
Console.WriteLine(exception.Message);
}
很可笑，不是吗？两种微软技术不能很好地合作！当它失败时，您会遇到什么错误？@Raghvenra-您能解释为什么使用Ping而不是
客户端。发送（消息）
