从 C# 中的不同线程启动计时器 [英] start a timer from different thread in c#

问题描述

我遇到了一些与计时器相关的问题.希望有人能帮忙..

Hi i have stepped into some problem related to timer. hope somebody can help..

1. 我有一个包含按钮的 Windows 窗体
2. 当我点击那个按钮时，我会启动一个参数化线程

Thread thread1 = new Thread(new ParameterizedThreadStart( execute2));
thread1.Start(externalFileParams);

1. 线程内部的代码执行得很好
2. 在这个线程的最后一行，我启动了一个计时器

.

public void execute2(Object ob)
{
    if (ob is ExternalFileParams)
    {
        if (boolean_variable== true)
          executeMyMethod();//this also executes very well if condition is true
        else
        {
            timer1.enabled = true;
            timer1.start();
            }
        }
    }
}

5 但定时器的滴答事件没有被触发

5 but the tick event of the timer is not fired

我正在研究 VS2008 3.5 框架.我已从工具箱中拖出计时器并将其 Interval 设置为 300 还尝试将 Enabled 设置为 true/false方法是 timer1_Tick(Object sender , EventArgs e) 但它没有被触发

I am working on VS2008 3.5 framework. I have dragged the timer from toolbox and set its Interval to 300 also tried to set Enabled true/false method is timer1_Tick(Object sender , EventArgs e) but its not fired

有人可以建议我做错了什么吗?

can anybody suggest what I am doing wrong?

推荐答案

您可以尝试以这种方式启动计时器:

You could try to start the timer this way:

在表单构造函数中添加:

Add in form constructor this:

System.Timers.Timer aTimer = new System.Timers.Timer();
 aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
 // Set the Interval to 1 second.
 aTimer.Interval = 1000;

将此方法添加到Form1:

Add this method to Form1:

 private static void OnTimedEvent(object source, ElapsedEventArgs e)
 {
   //do something with the timer
 }

在按钮点击事件上添加:

On button click event add this:

aTimer.Enabled = true;

这个计时器已经被线程化了，所以不需要开始一个新的线程.

This timer is already threaded so no need to start a new thread.
