我在我的代码中使用线程,线程是使用函数创建的:
private void InitializeBackgoundWorkers()
{
for (int f = 0; f < maxThreads; f++)
{
listBox1.Items.Insert(0, "Starting Thread : " + (f + 1));
threadArray[f] = new BackgroundWorker();
threadArray[f].DoWork +=
new DoWorkEventHandler(backgroundWorkerFiles_DoWork);
threadArray[f].RunWorkerCompleted +=
new RunWorkerCompletedEventHandler(backgroundWorkerFiles_RunWorkerCompleted);
threadArray[f].ProgressChanged +=
new ProgressChangedEventHandler(backgroundWorkerFiles_ProgressChanged);
threadArray[f].WorkerReportsProgress = true;
threadArray[f].WorkerSupportsCancellation = true;
}
}
doevent 是这样的:
private void backgroundWorkerFiles_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
int flag = 0;
while (rowCounter < allPostingRows.Tables[0].Rows.Count && flag == 0)
{
for (int i = 0; i < maxThreads; i++)
{
if (threadArray[i].CancellationPending == true)
{
flag = 1;
threadArray[i].CancelAsync();
worker.ReportProgress(0, "Thread Paused:");
}
}
if (flag == 0)
{
//perform work here
}
}
}
在按钮上,我尝试使用以下方法取消线程:
for (int i = 0; i < maxThreads; i++)
{
threadArray[i].CancelAsync();
}
我是否正确取消了线程?当他们被取消时,我看到列表框中的行说线程已取消,所以它确实进入了取消代码,但一段时间后它重新启动
谢谢
