如何在c#中使用smtp发送记录的电子邮件？

using System.Net;
using System.Net.Mail;

SmtpClient client = new SmtpClient("smtp.example.com", 587);
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential("your-email@example.com", "your-password");
client.EnableSsl = true;

MailMessage message = new MailMessage();
message.From = new MailAddress("your-email@example.com");
message.To.Add("recipient@example.com");
message.Subject = "邮件主题";
message.Body = "邮件正文";

client.Send(message);

using System.Net;
using System.Net.Mail;

class Program
{
    static void Main()
    {
        SmtpClient client = new SmtpClient("smtp.example.com", 587);
        client.UseDefaultCredentials = false;
        client.Credentials = new NetworkCredential("your-email@example.com", "your-password");
        client.EnableSsl = true;

        MailMessage message = new MailMessage();
        message.From = new MailAddress("your-email@example.com");
        message.To.Add("recipient@example.com");
        message.Subject = "邮件主题";
        message.Body = "邮件正文";

        client.Send(message);
    }
}
