.Net2.0最简单的邮件发送程序

注意现在的邮件服务器一般都要求验证。求证了一阵才知道怎么设置验证信息。一般都很简单啦，下面是最简单的代码：
namespace mailTest
{
    class Program
    {
        static void Main(string[] args)
        {
            string strFromAddr = //put the from address
            MailAddress from = new MailAddress(strFromAddr);
            MailAddress to = new MailAddress("xiaoyi__xy@163.com");
            MailMessage message = new MailMessage(from, to);
            message.Subject = "Using the SmtpClient class.";
            message.Body = @"Using this feature, you can send an e-mail message from an application very easily.";
            string server = "smtp.163.com";
            SmtpClient client = new SmtpClient(server);
            client.UseDefaultCredentials = false;
            client.Credentials = new System.Net.NetworkCredential(strUserName, strUserPassword);//Note here, credential validation is required.
            Console.WriteLine("Sending an e-mail message to {0} by using SMTP host {1} port {2}.",
                 to.ToString(), client.Host, client.Port);
            client.Send(message);
            Console.ReadKey();
        }
    }
}
