public class SmtpMail

The mail message can be delivered either through the SMTP mail service built into Microsoft Windows 2000 or through an arbitrary SMTP server. Types in the System.Web.Mail namespace can be used from ASP.NET or from any managed application.

If the SmtpServer property is not set, mail is by default queued on a Windows 2000 system, ensuring that the calling program does not block network traffic. If the SmtpMail property is set, the mail is delivered directly to the specified server.

The following example can be compiled to a console application that is used to send email from a command line. If you compile the example to a file named MailMessage.exe, use the executable file to send email as follows:

MailMessage to@contoso.com from@contoso.com test hello
using System;
using System.Web.Mail;

namespace SendMail
{
   class usage
   {
      public void DisplayUsage()
      {
         Console.WriteLine("Usage SendMail.exe <to> <from> <subject> <body>");
         Console.WriteLine("<to> the addresses of the email recipients");
         Console.WriteLine("<from> your email address");
         Console.WriteLine("<subject> subject of your email");
         Console.WriteLine("<body> the text of the email");
         Console.WriteLine("Example:");
         Console.WriteLine("SendMail.exe SomeOne@Contoso.com;SomeOther@Contoso.com Me@contoso.com Hi hello");
      }
   }


   class Start
   {
      // The main entry point for the application.
      [STAThread]
      static void Main(string[] args)
      {
         try

               MailMessage Message = new MailMessage();

               Message.From = args[1];
               Message.Subject = args[2];
               Message.Body = args[3];

               try
               {
                  SmtpMail.SmtpServer = "your mail server name goes here";
                  SmtpMail.Send(Message);
               }
               catch(System.Web.HttpException ehttp)
               {
                  Console.WriteLine("{0}", ehttp.Message);

               use.DisplayUsage();
            }
         }
         catch(System.Exception e)
         {
            Console.WriteLine("Unknown Exception occurred {0}", e.Message);
            Console.WriteLine("Here is the Full Message output");
            Console.WriteLine("{0}", e.ToString());
         }
