Send Email in .NET Core 2.0

在.NET Core 1.0 中，SMTP Client代码并没有被移植，直到.NET Core 2.0的发布。使用下面的代码：

static void Main(string[] args)
{
    SmtpClient client = new SmtpClient("smtp.163.com");
    client.UseDefaultCredentials = false;
    client.Credentials = new NetworkCredential("bidianqing123", "your password");

    MailMessage mailMessage = new MailMessage();
    mailMessage.From = new MailAddress("bidianqing123@163.com");
    mailMessage.To.Add("bidianqing@qq.com");
    mailMessage.Body = "body";
    mailMessage.Subject = "subject";
    client.Send(mailMessage);
    Console.WriteLine("发送成功");
    Console.ReadKey();
}

一定要确保框架是.NET Core 2.0，否则你将无法使用它。
