Question

can i make this loop continue in such a way that after last item in listbox to go to the first one and so on…

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    BackgroundWorker worker = sender as BackgroundWorker;
    for (int i = listBox1.Items.Count - 1; i >= 0; i--)
    {
        {
            if (worker.CancellationPending == true)
            {
                e.Cancel = true;
                break;
            }
            else
            {
                string queryhere = listBox1.Items[i].ToString();
                this.SetTextappend("" + queryhere + "\n");
                System.Threading.Thread.Sleep(500);
                worker.ReportProgress(i * 1);
            }
        }
    }
}

Any help would be greatly appreciated!

Thank you for all the answers

it seems that my list was going backwads so i must replace

 for (int i = listBox1.Items.Count - 1; i >= 0; i--)

with

 for (int i=0;i<ListBox1.Items.Count;i++)

Something like this ?

BackgroundWorker worker = sender as BackgroundWorker;
bool go = true;
while(go)
{
    for (int i = listBox1.Items.Count - 1; i >= 0; i--)
    {
        {
            if (worker.CancellationPending == true)
            {
                e.Cancel = true;
                go = false;
                break;
            }
            else
            {
                string queryhere = listBox1.Items[i].ToString();
                this.SetTextappend("" + queryhere + "\n");
                System.Threading.Thread.Sleep(500);
                worker.ReportProgress(i * 1);
            }
        }
    }
}
