推迟电子邮件的发送，而无需使用了Thread.Sleep C＃

问题描述

我有一个for循环循环通过和发送电子邮件的每个循环。现在即时通讯使用Thread.sleep（）方法，但我希望用户仍然能够使用该程序进行交互，只是德拉普一个循环。是否有可能做到这一点，而无需使用了Thread.Sleep？

I have a for loop which loops through and sends an email each loop. Right now im using thread.sleep() but I want the user to still be able to interact with the program, just delap that one loop. Is it possible to do this without using thread.sleep?

推荐答案

您运行UI线程的循环？如果是这样，只需使用Task.Factory.StartNew在不同的线程中运行你的循环。如果你需要延时的电子邮件在那个时候发送，放了Thread.Sleep真正开始之前的循环

Are you running the loop on the UI thread? If so, just use Task.Factory.StartNew to run your loop in a different thread. If you need to delay the email sending at that time, put a Thread.Sleep before you actually begin looping.

这将是这个样子：

private void OnButtonClick(object sender, EventArgs e)
{
    //This code happens on the UI thread
    Task.Factory.StartNew(SendEmails);
}

private void SendEmails()
{
    Thread.Sleep(500);

    foreach(var email in emailAddresses) {
        SendEmail(email);
    }
}
