백그라운드 작업자와 진행률 표시 줄의 구현을 찾고 있습니다. 내가 찾을 수있는 것은 Threading.Sleep()을 사용한 시뮬레이션입니다. 시뮬레이션을 실제 SQL 쿼리로 변경하면 샘플은 모두 작동하지만 작동하지 않습니다.BackgroundWorker 내의 SQL 쿼리

void m_oWorker_DoWork(object sender, DoWorkEventArgs e)
{
// The sender is the BackgroundWorker object we need it to
// report progress and check for cancellation.
//NOTE : Never play with the UI thread here...
for (int i = 0; i < 100; i++)
{
Thread.Sleep(100);
// Periodically report progress to the main thread so that it can
// update the UI. In most cases you'll just need to send an
// integer that will update a ProgressBar
m_oWorker.ReportProgress(i);
// Periodically check if a cancellation request is pending.
// If the user clicks cancel the line
// m_AsyncWorker.CancelAsync(); if ran above. This
// sets the CancellationPending to true.
// You must check this flag in here and react to it.
// We react to it by setting e.Cancel to true and leaving
if (m_oWorker.CancellationPending)
{
// Set the e.Cancel flag so that the WorkerCompleted event
// knows that the process was cancelled.
e.Cancel = true;
m_oWorker.ReportProgress(0);
return;
}
}
//Report 100% completion on operation completed
m_oWorker.ReportProgress(100);
}
