解决方案

您必须添加以下代码才能尽可能简单地发送邮件...



[给出了gmail帐户的示例。

这意味着您必须拥有一个Gmail帐户才能将邮件发送到任何地址。]

  string  pweda =   FromMailPassword;  //  （ConfigurationManager.AppSettings [password]）;  
  string   from  =   [e-mail];  //  将其替换为您自己的正确Gmail地址 
  string  to =   [e-mail];  //  将其替换为您要向其发送邮件的电子邮件地址 
系统。 Net.Mail.MailMessage mail =  new  System.Net.Mail.MailMessage（）; 
 mail.To.Add（to）; 
 mail.From =  new  MailAddress（ from ）; 
 mail.Subject =  这是一个测试邮件; 
 mail.SubjectEncoding = System.Text.Encoding.UTF8; 
 mail.Body =  测试邮件。; 
 
 mail.Priority = MailPriority.High; 
 SmtpClient client =  new  SmtpClient（）; 
 
  //  添加Creddentials-使用您自己的电子邮件ID和密码 
 client.UseDefaultCredentials =  false ; 
 client.Credentials =  new  System.Net.NetworkCredential（ from ，pweda）; 
 client.Port =  587 ;  //   Gmail适用于此端口 
 client.Host =   smtp.gmail.com; 
 client.EnableSsl =  true ;  //   Gmail适用于服务器安全层 
 
 尝试 
 {
 client.Send（mail）; 
 Response.Write（  Message Sent ...）; 
} 
  catch （例外情况）
 {
 Exception ex2 = ex; 
  string  errorMessage =  string  .Empty; 
  while （ex2！=  null ）
 {
 errorMessage + = ex2.ToString（）; 
 ex2 = ex2.InnerException; 
} 
 HttpContext.Current.Response.Write（errorMessage）; 
}  //  结束尝试 

如果您有任何其他信息，您可以从任何邮件地址发送...

只需更换您可以轻松获得的凭据，端口和主机名称谷歌。



您可以通过为'mail.Body'赋值来发送任何内容。



添加此项代码，你想要发送邮件...



快乐编码........

解决方案

You have to add the following codes to send a mail as simple as possible...

[Example is given for gmail account.
That means you have to have one gmail account to send a mail to any address.]

string pweda = "FromMailPassword"; //(ConfigurationManager.AppSettings["password"]);
        string from = "[e-mail]"; //Replace this with your own correct Gmail Address
        string to = "[e-mail]"; //Replace this with the Email Address to whom you want to send the mail
        System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
        mail.To.Add(to);
        mail.From = new MailAddress(from);
        mail.Subject = "This is a test mail";
        mail.SubjectEncoding = System.Text.Encoding.UTF8;
        mail.Body = "Test Mail.";
 
        mail.Priority = MailPriority.High;
        SmtpClient client = new SmtpClient();
 
        //Add the Creddentials- use your own email id and password
        client.UseDefaultCredentials = false;
        client.Credentials = new System.Net.NetworkCredential(from, pweda);
        client.Port = 587; // Gmail works on this port
        client.Host = "smtp.gmail.com";
        client.EnableSsl = true; //Gmail works on Server Secured Layer

        try
        {
            client.Send(mail);
            Response.Write("Message Sent...");
        }
        catch (Exception ex)
        {
            Exception ex2 = ex;
            string errorMessage = string.Empty;
            while (ex2 != null)
            {
                errorMessage += ex2.ToString();
                ex2 = ex2.InnerException;
            }
            HttpContext.Current.Response.Write(errorMessage);
        } // end try

You can send from any mail address if you have any other...
Just replace with the credentials and port and host names which you can get easily get from google.

You can send anything by assigning value to 'mail.Body'.

Add this code where ever you want send the mail...

Happy coding........
