解决方法
您可以拥有尽可能多的后台工作人员并同时运行.例：
var worker1 = new BackgroundWorker { WorkerReportsProgress = true };
var worker2 = new BackgroundWorker { WorkerReportsProgress = true };
DoWorkEventHandler doWork = (sender,e) =>
{
for (int i = 0; i < 10; i++)
{
var progress = (int)((i + 1) * 100.0 / 10);
var worker = (BackgroundWorker)sender;
worker.ReportProgress(progress);
Thread.Sleep(500);
}
};
worker1.DoWork += doWork;
worker2.DoWork += doWork;
worker1.ProgressChanged += (sender,e) =>
{
label1.Text = e.ProgressPercentage.ToString();
};
worker2.ProgressChanged += (sender,e) =>
{
label2.Text = e.ProgressPercentage.ToString();
};
worker1.RunWorkerAsync();
Thread.Sleep(1000);
worker2.RunWorkerAsync();
