多背景工作者+ C＃

Question

快速问题 - 是否有可能有两个后台工作人员同时运行？我似乎记得尝试过这一次，并得到一个错误，并似乎还记得阅读，你只能有一个......我找不到另一个线程，谈论有多个明确，虽然..

任何想法非常感谢！

干杯

，你喜欢和同时运行，您可以有很多的背景工人。示例：

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();
