DoWork of BackgroundWorker is called twice when RunWorkerAsync is called once?
- by Power-Mosfet
I have create a backgroundworker in an class it works, but if i call and wait until the end run, call it for the second time it will do the same process twice
i thinks there is somthing wrong with bw.DoWork +=
private void button1_Click(object sender, EventArgs e)
{
nptest.test.start("null", "null");
}
namespace nptest
{
class test
{
public static void start(string str, string strb)
{
if (bw.IsBusy != true)
{
bw.WorkerSupportsCancellation = true;
bw.DoWork += (obj, e) => bw_DoWork(str, strb);
bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted);
bw.RunWorkerAsync();
}
}
private static BackgroundWorker bw = new BackgroundWorker();
private static void bw_DoWork(string str, string strb)
{
System.Windows.Forms.MessageBox.Show("initializing BackgroundWorker");
}
private static void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
if ((e.Cancelled == true))
{
Console.WriteLine("Canceled");
}
else if (!(e.Error == null))
{
Console.WriteLine("Error: " + e.Error.Message);
}
bw.Dispose();
}
}
}
