用多线程发送邮箱（一次给一个用户发送N封邮件）
前台不用写，后台执行方法就可以了。
1 namespace SendMail 2 { 3 public partial class SendMail_Page : System.Web.UI.Page 4 { 5 protected void Page_Load(object sender, EventArgs e) 6 { 7 if (!IsPostBack) 8 { 9 ThStart(); 10 } 11 } 12 public Thread[] threads = new Thread[5]; 13 //开启线程 14 public void ThStart() 15 { 16 ThreadStart thsrt = new ThreadStart(SendMail); 17 //循环5个线程 18 for (int i = 0; i < 5; i++) 19 { 20 threads[i] = new Thread(thsrt); 21 threads[i].IsBackground = true; 22 } 23 //循环遍历所有的5个线程 24 foreach (Thread th in threads) 25 { 26 th.Start(); 27 } 28 } 29 30 public void SendMail() 31 { 32 try 33 { 34 System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(); 35 client.Host = "smtp.qq.com";//qq郵箱用這個，網易的就用smtp.126.com,看情況而定 36 client.UseDefaultCredentials = false; 37 client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; 38 client.Credentials = new System.Net.NetworkCredential("發送郵箱", "郵箱密碼");//驗證發送郵箱和這個一樣不 39 System.Net.Mail.MailMessage Message = new System.Net.Mail.MailMessage(); 40 Message.From = new System.Net.Mail.MailAddress("發送郵箱"); 41 Message.To.Add("接收郵箱"); 42 43 Message.Subject = "用戶測試"; 44 Message.Body = "主題——測試——郵箱發送"; 45 Message.SubjectEncoding = System.Text.Encoding.UTF8; 46 Message.BodyEncoding = System.Text.Encoding.UTF8; 47 Message.Priority = System.Net.Mail.MailPriority.High; 48 Message.IsBodyHtml = true; 49 client.Send(Message); 50 Thread.Sleep(1000); 51 } 52 catch (Exception) 53 { 54 //循环遍历所有的5个线程 55 foreach (Thread th in threads) 56 { 57 //中止线程 58 th.Abort(); 59 } 60 } 61 } 62 } 63 }
