如何让程序暂停几秒再执行

[bejco]

for (int j = 0; j < alist.Count; j++)
            {
                Thread mythread = new Thread(new ThreadStart(mu.add));
                mythread.Start();
            }

如何实现每循环一次暂停几秒再继续执行呢？

又学了点新的东西。学习中……

[24K純帥]

Sleep()

[Quote=引用 1 楼 zhoukang0916 的回复:]
C# codeSystem.Threading.Thread.Sleep(5000);//进程休眠5秒！

就是这个了.

[bejco]

还是没解决。

引用 17 楼 wuyq11 的回复:
Thread mythread = new Thread(new ThreadStart(mu.add));
mythread.Start();
Thread.Sleep(5000);




这样触发事件之后程序就无法响应了，奇怪的很。

你这里的Sleep是休眠的主线程...不停的new 新线程。。。。。有响应就诡异了

这个对的。

       for (int j = 0; j < alist.Count; j++)
            {
                string senderStr = alist[j].ToString();
                string[] str = senderStr.Split(new char[] { ',', ',',',' });
                string stmpStr = str[1];
                string fromStr = str[2];
                string pwdStr = str[3];
                string toMail = str[0];
                mailunit mu = new mailunit(stmpStr, fromStr, pwdStr, toMail, t_subject.Text, t_body.Text, paths);
                Thread mythread = new Thread(new ThreadStart(mu.SendMail2));
             mythread.Start();
            if(j>0)mythread.Sleep(5000);
     

            }

这样既简单有快捷的解决了你点击没反映的情况 自己试验下吧
因为当你掉用则个函数的时候 他就会触发睡眠5秒，不是点了没反应 是要等待5秒
就这样加了以后第一次等待去掉 就好了

肯定是放到一个button_click里面了。一点，一sleep，窗口就停止响应了。

用appliction.DoEvent()配合一下吧。

Thread.Sleep(5*1000)

[simen_frankly]

Thread.Sleep

[showjim]

for (int j = 0; j < alist.Count; j++)
            {
                string senderStr = alist[j].ToString();
                string[] str = senderStr.Split(new char[] { ',', ',',',' });
                string stmpStr = str[1];
                string fromStr = str[2];
                string pwdStr = str[3];
                string toMail = str[0];
                mailunit mu = new mailunit(stmpStr, fromStr, pwdStr, toMail, t_subject.Text, t_body.Text, paths);
                Thread mythread = new Thread(new ThreadStart(mu.SendMail2));
                mythread.Start();

            }

可以改为:

private ArrayList _alist;
private void time(object source, System.Timers.ElapsedEventArgs e)
        {
        string senderStr = _alist[0].ToString();
        _alist.RemoveAt(0);
        if(_alist.Count == 0) ((System.Timers.Timer)source).Close();
        string[] str = senderStr.Split(new char[] { ',', ',',',' });
        string stmpStr = str[1];
        string fromStr = str[2];
        string pwdStr = str[3];
        string toMail = str[0];
        mailunit mu = new mailunit(stmpStr, fromStr, pwdStr, toMail, t_subject.Text, t_body.Text, paths);
        mu.SendMail2()
        }

_alist = alist;
System.Timers.Timer timer = new System.Timers.Timer(5 * 1000);//5秒
timer.Elapsed += new System.Timers.ElapsedEventHandler(time);
timer.Enabled = true;
timer.Start();

[bejco]

楼上您这样是不是就不用多线程了？

[BitCoffee]

 //用timer控件也可以
 //全局变量
 int i = 0;
 
 //timer的click事件里:
 for (int j = i; j < alist.Count; j++)
 {
     Thread mythread = new Thread(new ThreadStart(mu.add));
     mythread.Start();
     i++;
     break;
 }

[bryht]

for (int j = 0; j < alist.Count; j++)
{
Thread mythread = new Thread(new ThreadStart(mu.add));
mythread.Start();
Thread.Sleep(1000);
}

还是多线程,新的线程由Timer触发,只是这个new和Start由Timer代理了.

[bejco]

我再把该部分完整代码贴出来，希望大家在此基础上改：

下面是主窗体程序部分：

       /*群发*/
        private void button1_Click(object sender, EventArgs e)
        {
            if (!check())
                return;
            //初始化
            toolStripProgressBar1.Visible = true;
            toolStripStatusLabel3.Text = "";
            toolStripProgressBar1.Maximum = t_to.Items.Count;

            ArrayList alist = new ArrayList();

            for (int i = 0; i < t_to.Items.Count; i++)
            {
                string mail;
                if (i < senderLst.Items.Count)
                {
                    mail = t_to.Items[i].ToString() + "," + senderLst.Items[i].ToString();
                   
                }
                else
                {
                    mail = t_to.Items[i].ToString() + "," + senderLst.Items[i % senderLst.Items.Count].ToString();
                }
                alist.Add(mail);

            }

            for (int j = 0; j < alist.Count; j++)
            {
                string senderStr = alist[j].ToString();
                string[] str = senderStr.Split(new char[] { ',', ',',',' });
                string stmpStr = str[1];
                string fromStr = str[2];
                string pwdStr = str[3];
                string toMail = str[0];
                mailunit mu = new mailunit(stmpStr, fromStr, pwdStr, toMail, t_subject.Text, t_body.Text, paths);
                Thread mythread = new Thread(new ThreadStart(mu.SendMail2));
                mythread.Start();

            }



          while (All.runing != 0)
            {
                toolStripProgressBar1.Value = t_to.Items.Count - All.runing;
                Application.DoEvents();
                toolStripStatusLabel3.Text = "发送成功：" + All.success.ToString() + "条  发送失败：" + All.fail.ToString() + "条";
            }
            toolStripProgressBar1.Visible = false;
            toolStripStatusLabel3.Text = "【结果】发送成功："+All.success.ToString()+"条  发送失败："+All.fail.ToString()+"条";
            All.success = 0;
            All.fail = 0;
            MessageBox.Show("【结果】发送成功：" + All.success.ToString() + "条  发送失败：" + All.fail.ToString() + "条");
        }

下面是mailunit类中SendMail2方法代码：

        /*发邮件：线程中使用*/
        public void SendMail2()
        {
            All.runing++;
            //创建smtpclient对象
            System.Net.Mail.SmtpClient client = new SmtpClient();
            client.Host = smtp;
            client.UseDefaultCredentials = false;
            client.Credentials = new System.Net.NetworkCredential(from, pwd);
            client.DeliveryMethod = SmtpDeliveryMethod.Network;

            //创建mailMessage对象 
            System.Net.Mail.MailMessage message = new MailMessage(from, to);
            message.Subject = subject;
            //正文默认格式为html
            message.Body = body;
            message.IsBodyHtml = true;
            message.BodyEncoding = System.Text.Encoding.UTF8;

            //添加附件
            if (paths.Count != 0)
            {
                foreach (string path in paths)
                {
                    Attachment data = new Attachment(path, System.Net.Mime.MediaTypeNames.Application.Octet);
                    message.Attachments.Add(data);
                }
            }

            MessageBox.Show("1");
            System.Threading.Thread.Sleep(5000);
//            MessageBox.Show("2");

            try
            {
                client.Send(message);                
                All.success++;
                All.runing--;

            }
            catch (Exception ex)
            {
                All.fail++;
                All.runing--;
            }

             

        }

多谢大家，问题已经解决，其实sleep是可以的，只不过窗体假死而已，为了避免窗体假死的情况，可以使用
Application.DoEvents()。
再次感谢大家的帮助！

这个是正确的
