我在给定的特定时间运行backgroundworker时遇到问题.
private void button1_Click(object sender,EventArgs e)
{
backgroundWorker1.RunWorkerAsync();
}
然后在backgroundWorker1_DoWork中：
private void backgroundWorker1_DoWork(object sender,DoWorkEventArgs e)
{
backgroundWorker1.CancelAsync();
}
最后在backgroundWorker1_RunWorkCompleted中：
private void backgroundWorker1_RunWorkerCompleted(object sender,RunWorkerCompletedEventArgs e)
{
backgroundWorker1.RunWorkerAsync();
}
我想连续运行背景,但每5秒或超过5秒.
如果有人能帮助我,我将非常感激,
提前致谢.
解决方法
运行
Timer类表示Timer控件,用于在运行时创建Timer.以下代码段在运行时创建Timer,设置其属性和事件处理程序.
Timer t = new Timer(); t.Interval = 2000; timer1.Enabled = true; timer1.Tick += new System.EventHandler(OnTimerEvent);
事件处理程序代码如下所示.
private void OnTimerEvent(object sender,EventArgs e)
{
backgroundWorker1.RunWorkerAsync();
}
