应用线程并执行两项任务 [英] Applying threading and performing two tasks

问题描述

各位大家好，



我有一个控制台应用程序，我必须发送邮件，并且必须每5分钟检索一次来自第三方的邮件统计信息。因为我必须发送更多数量的邮件，可能需要4-5个小时，我迫不及待想要完成它而不是开始获取统计数据。所以我必须每5分钟应用线程发送邮件和检索统计数据..

我已经为它制作了一个类文件



如何在此处使用计时器并将其设置为每隔5分钟触发一次

解决方案

请参阅MSDN线程教程 [ ^ ]



你应该创建两个线程，一个用于统计，一个用于统计发送电子邮件。

在你的代码中你应该有：

公共类SomeForm：表格
 {
 private Thread _sendEmailsThread; 
 private Thread _getStatisiticsThread; 
 
 
 protected void SomeUIEventMethod（...）
 {
 
 if（_sendEmailThread == null || _sendEmailThread.IsAlive == false）
 {
 _sendEmailsThread = new Thread（new ThreadStart（SendEmails））; 
 _sendEmailThread.Start（）; 
} 
 
 if（_getStatisiticsThread == null || _getStatisiticsThread.IsAlive == false）
 {
 _getStatisiticsThread = new Thread（new ThreadStart（GetStatisitics））; 
 _getStatisiticsThread.Start（）; 
} 
 
} 
 
 private void SendEmails（）
 {
 // ...您发送电子邮件的代码
 } 
 
 
 private void GetStatisitics（）
 {
 // ...获取统计数据的代码
} 
 
 protected void SomeForm_FormClosing（...）
 {
 if（_sendEmailThread！= null&& _sendEmailThread.IsAlive）
 {
 _sendEmailThread.Abort（）; 
} 
 if（_getStatisiticsThread！= null&& _getStatisiticsThread.IsAlive）
 {
 _getStatisiticsThread.Abort（）; 
 
} 
 // ... 
 
} 
 
 
} 

您可以使用.net框架提供的后台工作组件来创建线程，因此您可以创建一个在继续执行时在不同线程中发送电子邮件的类。



排序的一个例子，

< br /> 
 Public Class Email< br /> 
< br /> 
 Private EmailWorker As New ComponentModel.BackgroundWorker< br /> 
< br /> 
 Public Sub SendEmailsAsync（ ）< br /> 
 EmailWorker.WorkerReportsProgress = True< br /> 
 AddHandler EmailWorker.DoWork，AddressOf EmailWorker_DoWork< br /> 
 AddHandler EmailWorker.ProgressChanged，AddressOf EmailWorker_ProgressChanged< br /> 
 AddHandler EmailWorker.RunWorkerCompleted，AddressOf EmailWorker_Completed< br /> 
 EmailWorker.RunWorkerAsync（）< br /> 
 End Sub< br /> 
< br /> 
 Private Sub EmailWorker_Completed（发件人为对象，e为ComponentModel.RunWorkerCompletedEventArgs）< br /> 
'发送所有电子邮件后您想要做的任何事情< br /> 
 End Sub< br / > 
< br /> 
 Private Sub EmailWorker_Progress已更改（发件人为对象，e为ComponentModel.ProgressChangedEventArgs）< br /> 
'进度，即如果您希望在每封电子邮件或类似内容之后进行任何记录< br /> 
 End Sub< br /> 
< br /> 
 Private Sub EmailWorker_DoWork（ByVal sender As Object，ByVal e As EventArgs）< br /> 
'编写代码以发送电子邮件< br /> 
 EmailWorker.ReportProgress（1，string message）< br /> 
 End Sub< br /> 
< br /> 

Hello everybody,

I have a console application from where I have to send mails and have to retrieve statistics about mail from third party at every 5 minutes. As I have to send more number of mails and it may take 4-5 hours, i can not wait to get it over and than start getting statistics. So I have to apply threading for sending mail and for retrieving statistics every 5 minutes..
I have made a class file for it

How can I use timer here and set it to trigger after every 5minutes

解决方案

See MSDN Threading Tutorial[^]

You should create two threads, one for statistics and one for sending emails.
In your code you should have:

public class SomeForm : Form
{
private Thread _sendEmailsThread;
private Thread _getStatisiticsThread;


protected void SomeUIEventMethod(...)
{

if(_sendEmailThread == null || _sendEmailThread.IsAlive == false)
{
_sendEmailsThread= new Thread(new ThreadStart(SendEmails));
_sendEmailThread.Start();
}

if(_getStatisiticsThread== null || _getStatisiticsThread.IsAlive == false)
{
_getStatisiticsThread= new Thread(new ThreadStart(GetStatisitics));
_getStatisiticsThread.Start();
}

}

private void SendEmails()
{
//... your code for sending emails
}


private void GetStatisitics()
{
//... your code for getting statistics
}

protected void SomeForm_FormClosing(...)
{
if (_sendEmailThread!= null && _sendEmailThread.IsAlive)
{
        _sendEmailThread.Abort();
}
if (_getStatisiticsThread!= null && _getStatisiticsThread.IsAlive)
{
        _getStatisiticsThread.Abort();

}
//...

}


}

You can use background worker component provide by .net framework for creating threads and thus you can create a class which sends out emails in a diffrent thread while you continue with your execution.

An example of sort,

<br />
Public Class Email<br />
    <br />
    Private EmailWorker As New ComponentModel.BackgroundWorker<br />
    <br />
    Public Sub SendEmailsAsync()        <br />
        EmailWorker.WorkerReportsProgress = True<br />
        AddHandler EmailWorker.DoWork, AddressOf EmailWorker_DoWork<br />
        AddHandler EmailWorker.ProgressChanged, AddressOf EmailWorker_ProgressChanged<br />
        AddHandler EmailWorker.RunWorkerCompleted, AddressOf EmailWorker_Completed<br />
        EmailWorker.RunWorkerAsync()<br />
    End Sub<br />
<br />
 Private Sub EmailWorker_Completed(sender As Object, e As ComponentModel.RunWorkerCompletedEventArgs)<br />
        ' Anything you wish to do after all the emails are sent <br />
    End Sub<br />
<br />
    Private Sub EmailWorker_ProgressChanged(sender As Object, e As ComponentModel.ProgressChangedEventArgs)<br />
        ' Progress i.e if you wish to have any logging after each email or somthing similar <br />
    End Sub<br />
<br />
    Private Sub EmailWorker_DoWork(ByVal sender As Object, ByVal e As EventArgs)<br />
      ' Write Your Code to Send Emails <br />
              EmailWorker.ReportProgress(1,string message )<br />
    End Sub<br />
<br />
