示例

下面的代码示例显示电子邮件的目标。

static void CreateTestMessage4( String^ server )
{
   MailAddress^ from = gcnew MailAddress( L"ben@contoso.com" );
   MailAddress^ to = gcnew MailAddress( L"Jane@contoso.com" );
   MailMessage^ message = gcnew MailMessage( from,to );
   message->Subject = L"Using the SmtpClient class.";
   message->Body = L"Using this feature, you can send an email message from an application very easily.";
   SmtpClient^ client = gcnew SmtpClient( server );
   Console::WriteLine( L"Sending an email message to {0} by using SMTP host {1} port {2}.", to, client->Host, client->Port );
   client->Send( message );
   client->~SmtpClient();
}

public static void CreateTestMessage4(string server)
{
    MailAddress from = new MailAddress("ben@contoso.com");
    MailAddress to = new MailAddress("Jane@contoso.com");
    MailMessage message = new MailMessage(from, to);
    message.Subject = "Using the SmtpClient class.";
    message.Body = @"Using this feature, you can send an email message from an application very easily.";
    SmtpClient client = new SmtpClient(server);
    Console.WriteLine("Sending an email message to {0} by using SMTP host {1} port {2}.",
         to.ToString(), client.Host, client.Port);

    try
    {
        client.Send(message);
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception caught in CreateTestMessage4(): {0}",
            ex.ToString());
    }
}

注解

此方法返回的字符串不一定与创建实例时指定的字符串相同。 如果 属性 DisplayName 不 null 等于 String.Empty (“”) ， ToString 则返回使用以下语法组成的字符串：

DisplayName <User@Host>

如果 DisplayName 为 null 或 等于 String.Empty， ToString 则返回 属性的值 Address 。
