用C＃发送电子邮件？

我正在尝试发送邮件，但此代码引发错误“发送失败”

MailMessage MailMesaji = new MailMessage(); MailMesaji.Subject = "subject"; MailMesaji.Body = "mail body"; //MailMesaji.BodyEncoding = Encoding.GetEncoding("Windows-1254"); // Turkish Character Encoding MailAddress mdrom = new MailAddress("[e-mail]"); MailMesaji.From = mdrom; MailMesaji.To.Add(new MailAddress("[e-mail]")); System.Net.Mail.SmtpClient Smtp = new SmtpClient(); Smtp.Host = "mail.verydindai.com"; // for example gmail smtp server Smtp.EnableSsl = true; Smtp.Port = 465; Smtp.Credentials = new System.Net.NetworkCredential("amit.pandey", "1234567"); Smtp.Send(MailMesaji); 

请告诉我解决方案？ 如果你有其他解决方案告诉我？

Answer 1

我写下了一个控制台应用程序，请尝试使用此示例。 使用您的凭据要发送地址，来自地址，密码，正文

 using System; using System.Text; using System.Net.Mail; using System.Net; namespace TestingConsole { class Program { static void Main(string[] args) { try { string to = "[e-mail]"; string from = "[e-mail]"; string from_pwd = "mypassword"; string subject = "Sample Mail testing"; string body = "Wow this is testing body"; MailMessage mM = new MailMessage(); mM.From = new MailAddress(from); mM.To.Add(to); mM.Subject = subject; mM.Body = body; mM.IsBodyHtml = false; mM.Priority = MailPriority.High; SmtpClient sC = new SmtpClient("smtp.gmail.com"); sC.Port = 587; sC.Credentials = new NetworkCredential(from, from_pwd); sC.EnableSsl = true; sC.Send(mM); } catch (Exception e) { Console.WriteLine(e.Message + " " + e.StackTrace); } } } }

不是gmail使用不同的端口为smtp然后默认25？

Answer 3

  string to = ""; string from = ""; string from_pwd = ""; MailMessage mM = new MailMessage(); mM.From = new MailAddress(from); mM.To.Add(to); mM.Subject = subject; mM.Body = body; mM.IsBodyHtml = true; mM.Priority = MailPriority.High; SmtpClient sC = new SmtpClient("smtp.gmail.com"); sC.Port = 587; sC.Credentials = new NetworkCredential(from, from_pwd ); sC.EnableSsl = true; sC.Send(mM); 

Answer 4

您可能需要更改您要连接的端口，我认为如果启用SSL，谷歌应该是465或587。

还要检查是否有一些可能干扰的AntiVirus软件。 AV软件停止自定义软件发送电子邮件是很常见的。 可能还有一些防火墙无法通过所需的端口。
