winform 在backgroudwork的Dowork事件里如何调用控件

Answer 1

private void Button1_Click(object sender, EventArgs e)
{
this.backgroundWorker1.RunWorkerAsync();//调用Dowork事件
}

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{

BackgroundWorker worker = (BackgroundWorker)sender;
}

private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
//进程序处理
}

private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
//进程序完成响应事件
}

Answer 2

你是想跨线程调用控件吧？建议用委托比较简单，backgroudwork麻烦
